Advanced Energy Management (AEM): System Description

A key element of the AEM system is the variable spot pricing concept, which varies the price of electric energy during the day and seasons in relation to the cost of producing energy (e.g., Gulf Power’s RSVP Rate). Although the equipment may provide the capability for direct load control or other functionality, primary emphasis is placed on the AEM system’s ability to automatically respond to price signals as the means for effecting load shape changes. Thus, there must be a high degree of integration between the pricing and control components of the AEM system.

The AEM system will connect the utility and the customer through communications links to the customer’s home. As a result, the customer’s system is able to communicate with the utility and, as price levels change, the customer’s pre-programmed instructions regarding their desired comfort levels will adjust electricity use for heating, cooling, water heating and another selected appliance automatically. Therefore, the customer’s control of the electric xxxx is accomplished by allowing him to choose different comfort levels at different price levels in accordance with his individual lifestyles.

The AEM systems shall be customer-programmable and shall have the ability to automatically respond to a fixed schedule of seasonally differentiated time of use prices and also receive and respond to critical price signals communicated to participating households on a real-time basis.

A basic AEM system would allow the customer to control more precisely the amount of electricity purchased for heating, cooling, water heating, and another selected load through customer-programmed automated responses by their HVAC systems, water heaters, and all other major electricity consuming device or appliance. These systems, devices, ;and appliances are programmed by the customer to automatically respond to changes in electricity prices and to changes in day-type, time-of-day, and season.

The various components of the AEM system installed in the customer’s home, as well as the components installed at Gulf Power and, in between, provide communication capability between the customer and the utility. The combination of the AEM system and Gulf’s innovative variable rate concept, will provide consumers with the opportunity to modify their usage of electricity in order to purchase energy at prices that are somewhat lower to significantly lower than standard rates, most of the time. Further, the communication capabilities of the AEM system will allow Gulf Power to send a critical price signal to the customer’s premises during extreme peak load conditions. The result is a demand reduction attributable to pre-determined thermostat and relay settings, chosen by the participating customer, which are automatically activated upon receipt of the critical price signal.

A - 1

Scientific-Atlanta

Proprietary Information

A basic AEM system will also enable Gulf Power Company to automate certain manual functions (e.g., meter reading, outage notification, load research, and tamper detection) thus improving operational efficiencies and further increasing customer satisfaction.

The basis AEM system will be available and marketed to all residential customers within Gulf Power’s service area. This program will provide participating customers with the information needed to program their AEM systems to respond to pricing signals embodied in Gulf’s RSVP rate and those generated by the utility during peak load conditions on a near real-time basis. Gulf’s full scale implementation of this program will begin as soon as possible.

An upgraded version of the basis AEM system described above will be offered to customers as an added-cost option. This upgraded version will require a more elaborate user interface and controller within the residence and will offer customers added functionality. These value-added features include:

multiple HVAC zone programmable control

capability to display:

electricity consumption by tier and total since last xxxx

the electricity cost to date since last xxxx

estimated electric xxxx for current month

electric xxxx comparison (current month vs. same month last

year)

electric xxxx comparison (RSVP vs. RS)

messaging of various kinds

capability to support an optional home security system and other

home automation products and services

Gulf Power intends to offer its residential customers choices of home automation, home security and home energy management options. These options will be offered as they become marketable and cost-beneficial to Gulf Power, its stockholders and its customers.

B.1.4.2 Customer-Controlled Load Management (CCLM)

Scientific-Atlanta will supply software that supports two-way CCLM, TOU and CTP applications. End-use devices, defined as two-way load control relays (LCRs) and/or home user interface (SuperStat and/or other such devices), will be located at the customer site and will respond to commands generated by the two-way load management and CTP applications. The application software will enable:

• two-way communication of the configuration between the in-home devices and the Head-End;

• CTP by automatically transmitting critical pricing signals through the Gateway to the SuperStat;

• TOU pricing based on clocks and calendars that incorporate weekends and holidays;

• provisioning TOU devices (HVAC, LCRs, etc.) for price tiers;

• time and date synchronization of the Gateway via periodic real-time WAN communication;

• the CTP application to allow utility controlled water heater override during critical price tier.

• the accounting for the number of hours in the critical tier for each customer and the disallowance of critical tier implementation above a designated number of critical tier hours;

• a minimum of *** (variable) warning before critical tier initiation;

• the disallowance of critical tier implementation if the minimum *** (variable) warning is not received at the Gateway; and

• • the uploading of the number of times a critical tier was implemented since last communication.

B1.4.3 Outage Notification (optional)

The Gateway paging/telephony WAN card allows for power outage monitoring. When voltage drops below a pre-defined level, the Gateway will report the drop using the WAN return path, similar to Scientific-Atlanta’s LOCATE device. The Media Access

Proprietary Information

Controller (MAC) will flag outages when the Gateway reports to the Head-End. This failure may be caused by power or equipment failures. Upon an outage or upon a restoration, a message will be sent to the network diagnostics platform. The network diagnostics platform displays the message and logs the transaction.

B.1.4.4 Tamper Detection (Optional)

Tampering with the meter or the Gateway can be sensed by a removal or disconnection of the electric meter or Gateway. This will set a flag in the Gateway memory that the event occurred and send the message to the network diagnostics platform for display and logging. The network diagnostics application will also be responsible for notifying Gulf Power Company that a breach has occurred and it will store the date/time of the event.

B.1.4.5 Remote Service Reconnect i Disconnect (SRD) (Optional)

The Scientific-Atlanta SRO whole-house disconnect device can be incorporates into the Gateway as an option. A *** amp load relay with a hardwired link to the Gateway will facilitate power reconnect/disconnect. Upon receiving a signal from the SRD application, a contactor will reconnect or disconnect power to the customer. A confirmation message that the operation was successful will be returned to the Head-End. IIf the meter is equipped with an AMR module, the meter will be read after power has been disconnected and the reading reported to the AMR application. At power restoration, the meter will be read before the contactor allows power to flow to the customer.

B,1.4.6 Surge Suppression Monitoring (Optional)

Scientific-Atlanta will offer an optional Gateway surge suppressing Metal Oxide Varistor (MOV) device with failure sensory circuits. This surge suppression can provide whole-house transient resistance for electric motors. The Gateway will notify the Head-End network diagnostics program if the surge suppression has been expended so that the Gateway surge suppressor can be repaired.

8.1.4.7 Network Diagnostics Program

B.2 MEDIA ACCESS CONTROLLER

The Media Access Controller (MAC) will provide the main communication link between the Utility Host and the Customer Premise Equipment (CPE). The MAC is implemented on Microsoft Windows NT running on an Intel Pentium-class workstation. For Gulf Power Company, the main communication media will be outbound VHF paging through a paging service provider and an inbound, twenty-four (24) channel, telephony link through a T1 circuit from the telephone services provider.

The Pagina/Telephony (PT) MAC is connected directly to the Network Controller via TCP/IP on:

• 10Base-T Ethernet;

• 100Base-T Ethernet;

• Point-to-Point Protocol (PPP) over dial-up telephone;

• PPP over ISDN, or

• PPP over T1.

The PT MAC connects to the paging service provider via modern over a dedicated leased or dial-up telephone line. The paging protocol is SA-206 using global, group and individual address methodology in a variable length message. The SA-206 protocol will also support other customer services such as direct load control, local/wide spread storm warning notification, etc.

Messages returned from the CPE will be via telephony link using a Scientific-Atlanta UNM type communications protocol. A T1 circuit will provide twenty-four (24) inbound channels from the telephone service provider. The FT MAC can handle all 2-A. channels contiguously.

Additional MACS can be used locally and remotely to provide additional paging and/or telephone throughput or to communicate through other media such as broadband, LLEO, and two-way radio frequency (RF).

B.3 GATEWAY AND LOCAL AREA NETWORK INTERFACE

The MainGate Gateway consists of one WAN and up to three LAN cards (along with their associated firmware) contained in a secure, weather-proof enclosure designed for mounting between the electrical meter and the meter base. Power to the Gateway is supplied by the line side of the meter base. Communications from the Head-End is via paging signals to an antenna built into the Gateway. Communications from the Gateway to the Head-End is done via the customer’s telephone line (normally during low-use, night-time hours). Communications between the Gateway and the SuperStat is via two-way RE transport using CEBus protocol. Communication between the Gateway and the load control relays is via CEBus PLC. The Gulf Power Company meter interface is a CEBus PLC or a sophisticated dial encoding device. The Gateway will meet or exceed the IEEE C3790a-1974 specification on transient protection at the power supply and modem interfaces.

Gateway WAN options will also include, among others, broadband, low earth orbit (LLECO), and RS-232 two-way RF (as defined in Exhibit K).

The various functions of the MainGate Gateway will be listed and defined individually.

B.3.1 Gateway WAN Communications

B.3.1.1 Commands Received by the Gateway VHF Paging Interface

Commands received by the VHF paging interface are;

1) Global responses

2) Group responses

3) Individual responses

All Include:

a) Initiate CTP tier 1

b) Initiate CTP tier 2

c) Initiate CTP tier 3

d) Call home immediately

e) Call home random

f) Cancel CTP

g) Initiate Direct Load Control @ 100%

1) Cancel All Pending Calls

The VHF paging interface will deliver control commands to the hardwire application using the standard Gateway bus protocol. The hardwired interface will then interpret the commands and execute the proper controls. The VHF paging interface wili follow all rules for outdoor equipment and will have sensitivity at least equal to 20 uVm,

B-8

Scientific-Atlanta

Proprietary Information

B.3.1.2 Commands Transmitted by the Gateway Telephony Interface

The telephony interface will provide telephony WAN services to the Gateway. A Scientific-Atlanta UNM-type communications protocol, with 16-bit CRC error detection, will be used. This-protocol will provide the main communications between the Head- End and the Gateway.

The following commands will be supported by the telephony interface, and will be communicated to the hardwired interface via the standard bus protocol:

• AMR reading of 12 accumulators;

• Clearing of intermediate accumulators (after data is verified

• Set Clock;

• Set Calendar,

• Download TOU schedules (Time / Day / Accumulator #) to the Gateway;

• Download meter reading (call in) time to application; and

• Perform all CEBus functions via the powerline carrier (PLC) and RF interfaces.

The telephony interface must have a serial number for unique identification of the Gateway. It is required that the telephony and paging interfaces share the same ID (serial) number. This will readily identify the device in both media.

The telephony interface will be an outgoing call only device in that it will not detect ringing voltage nor will it answer the phone. When a call is queued, the telephony Interface will check for off-hook via a voltage measurement. When the line is determined to be available, the device will place the call using dial tone detection or pulse dialing. In home off-hook detection (line in-use) will be required. If the customer picks-up the telephone during data transmission, the customer will hear a data tone and the data session will end. The customer must then hang-up and pick-up the telephone again to get a dial tone. A dynamic circuit to detect the difference between single and double termination.

The telephony interface will be parallel and will not be polarity sensitive. Hardwired telephony inputs telephony will be in the form of screw terminations. It is understood that the transient suppression circuitry operates in a hostile environment and very high transients may be generated in a fault condition. Transient suppression will be incorporated into the telephony WAN card in such a way as to isolate the power system from the telephony system, will meet or exceed the IEEE 03790-1989 standard for transient protection and will adhere to FCC Part 68 regulations.

8.3.2 Meter Dial Encoder interface

The meter dial encoder interface will read pulses from standard watt hour meters (or VAR meters), and will store the pulses in a set of accumulators. There will be 12 accumulators available, and each will be responsive to TOU and/or critical tier price signaling. Each accumulator will be a constant type in that it will never be reset but will be allowed to roll over in normal operation. The following are specifications for the dial encoder interface:

• Accumulator value will be 16 bits.

B-9

Scientific-Atlanta

Proprietary Information

• Compatible with hard contacts or optical interface.

• Accumulators will be held in non-volatile memory, protected so as to preserve data integrity even during power loss.

• Accumulators are responsive to a schedule table which is downloaded to the Gateway.

The dial encoder interface will provide a full function time and date calendar. The calendar can allow weekends and holidays to be processed differently or excluded from TOU control altogether. It will also allow weekends and holidays to be moved to a weekend or holiday schedule while allowing CTP to commence at.any time. CTP can be initiated by the Head-End at any time, and will direct the pulses to CTP accumulators (included in the 12 total accumulators). The purpose of the calendar function is to allow at least six TOU rates to be downloaded into the calendar along with pointers to accumulators. The calendar will also allow rates to be switched automatically among four schedules at predetermined times and dates. For example, Summer and Winter TOU prices could be different and the schedules could change at pre-determined times and dates. The following information applies to the way accumulators in the dial encoder interface work:

• Schedule tables direct the accumulators in the Gateway;

• A single accumulator can respond to more than one time;

• An accumulator is the equivalent of a price;

• Time is kept in 24 hour increments;

• A maximum of 24 holidays can be programmed; and

• Days are recorded in such a way that permit weekends and holidays to be distinguished from work days. The weekend exemptions can be waived making weekends just another schedule.

An illustration of the time/date function is shown for the purpose of clarity.

This, or a similar arrangement, will allow Gulf Power Company to use TOU rates and allow seasonal changes without the need for real-time communications.

CTP will coordinate with the Head-End CCLM application to direct the accumulator pointers to unused accumulators so that CTP will override any current or pending schedule. Changes in schedule will not override or cancel the CTP signaling. CTP signals will include the start time and the end time. A cancel command will be available so that CTP can be canceled. If CTP is canceled, the regular TOU schedule will apply.

Open time periods (that is, not specified periods in the schedule) will result in data being directed to a default accumulator. In the above example accumulator #1 was left vacant for that purpose. A default accumulator will be defined so that there is never any ambiguity about where data are to be stored. The following information defines accumulator parameters:

***.

CTP is a critical feature that is of high value to the utility. A record will be kept of CTP activity and communicated when a scheduled (or unscheduled) meter read takes place. There will be sufficient memory to store *** occurrences of CTP per ***. ***.

Scientific-Atlanta

Proprietary Information

CCLM (Customer Controlled Load Management) is a function that Gulf Power Company desires to use at the customer site. This requires the addition of a two-way SuperStat and provides for the addition of multiple load control devices. In an CTP event, the Gateway will send signals to the thermostat and load control modules for the purpose of reducing the power consumption and thus the cost to the customer. if communication to the thermostat is not available, CTP may be disallowed. A table of necessary communications will be provided to a local application to determine if CTP is to be invoked or aborted.

A table will be provided with the following functions:

CTP Table

Device Number		Communications Required to the SuperStat?
AAAAAAAAAA		Yes
BBBBBBBBBBB		Yes
CCCCCCCCCCC		No
DDDDDDDDDD		No

For TOU, a table will also be provided. This table may allow TOU to occur regardless of the availability of communications.

TOU Table

Device Number		Communications Required to the SuperStat?
AAAAAAAAAA		Yes
BBBBBBBBBBB		No
CCCCCCCCCCC		No
DDDDDDDDDD		No

If CTP is exempted for lack of communications, the event will be recorded as a failed CTP event with a code for the reason for failure and the specific device number (or numbers) that failed.

If the TOU option requires communications, a similar log will be kept for TOU failures.

The application will make several attempts to communicate the CTP or TOU event to the load devices and the SuperStat. These attempts will be in concert with the CEBus methodology and may be invoked more than one time. What is meant is that the CEBus transport will automatically make N attempts to communicate but if communications fail, the application may restart the process M times,

In the event that either TOU or CTP is exempted due to failed communications, the Gateway will control any available devices as if TOU was in effect, and will maintain the error log.

B.3.3 The TOU / CTP Application

The following is an overall summary of the TOU/CTP application operation:

• Clock and Calendar functions will be non-volatile and operable in a power outage condition;

• Time will be broadcast upon restoration of power following an outage and on a periodic basis,

• 12 accumulators will be provided, each corresponding to a price/time;

• Time, day, and Weekend or Holiday exemptions will drive the accumulator pointers;

• Time is in 24 hour quantities to eliminate AM / PM issues;

• Daylight savings time is handled by schedule changes (A to B to A);

• Weekends are identified for differentiation;

• Holidays are listed for differentiation (Up to 24);

• CTP will override TOU in one hour increments;

• CTP is cancelable;

• CTP can be exempted by device failures;

• Communications tables define CTP exemptions;

• Error logs are maintained for exemptions;

• Next read date is set for the telephony to call in at a predetermined time;

• The Gateway will control devices per CTP or TOU;

• The Gateway will transmit load control data on a periodic basis;

• Ability to read and write programs in the SuperStat.

The TOU/CTP application will be capable of checking for the errors defined in the preceding tables and will queue error report calls. The calls can be scheduled to be immediate (random over an N minute period) or they can be delayed to the next available call window, or they may be logged until the next meter read. The data will be presented to the host application at communication and will not be cleared as a result of the communication. The error log will be at least *** entries deep and will recirculate showing the last *** errors in the buffer regardless of the interval in which they occurred.

The TOU/CTP application will interact closely with the SuperStat in the execution of TOU. The referenced time-of-use does not refer to different billing prices lout to time of customer preference only.

B.3.4 The Meter Reading Application

As previously discussed, the Gateway will check for communication with the SuperStat and make decisions as to whether to implement CTP or TOU per schedules, or per command. All schedule information is to be downloaded to the Gateway by telephony during the initialization session. The clock and calendar will be refreshed (synchronized) during subsequent communication sessions, such as scheduled meter reads.

Meter reads will be made at intervals determined by Gulf Power Company. For example, Gulf Power Company may wish a population of meters to be read on certain days. The Head-End will download to the Gateway the time and date of the next meter read. At that time, the Gateway will begin a process to make a call to the Head-End for the purpose of data transfer. The line will be monitored for “in-use” condition. If the line is in use, the call will be delayed until it is clear. If the line is available, the call will be placed immediately and communications will commence. The application will make a request to the telephony WAN interface for a session and the telephony WAN will deal with the request until such time as the communication is established. The Gateway will continue to request a session until such time as the condition is satisfied by a successful communication to the Head-End. The telephony WAN application may have some rules that limit the number or tries or the time period when communications are allowed.

When telephone communications are established, the accumulator data will be sent to the Head-End and the Head-End will acknowledge receipt of the data and send the following data to the Gateway: set the clock, calendar, and the call back time. The new meter read data will be stored in non-volatile memory.

A local PC, as an option, can have access to the Gateway via PLC communications and will have software for the purpose of reading the meter. A method of supplying meaningful data would be for the application to store accumulators with kWh since last “Billing Read”. This set of accumulators is for reference only and is reset by the Head-End after it performs a “Billing Read”.

When a successful “Billing Read” is accomplished, the resetable accumulators will be reset signifying the beginning of a new billing period. Intermediate meter reads for reference may be made at any time and do not affect the working accumulators or other fields. During any accumulator read, the clock, calendar, TOU schedules, or other parameters may be redefined or set by the Head-End.

The local PC will have access to data on a read only basis. It may inquire about any piece of data but may not reset or reconfigure any parameters. All accumulators are available as are the schedules and read dates. Very specific commands will be issued by the PC to acquire data via PLC. Care must be taken to limit access to read only so that data security is preserved. Similarly, data security must be provided on the telephony interface so that hackers cannot gain access to the data or schedules. Please note that the working accumulators are not resetable under any type of software control.

It is important to note that this interface is being designed specifically for the purpose of providing TOU in low bandwidth networks. As a result, the clock will normally be set

during meter reads and will be fully backed up and operational during power outage conditions. A period of three days is supplied for standby operation. Other services in the Gateway LAN will not be operational under this power outage condition.

B.3.5 RF and PLC Applications

The LAN capabilities include a Hardwire interface for AMR, two-way CEBus PLC communications to appliances/load control relays and two-way CEBus protocol through a RF transport to the SuperStat. The Hardwired AMR is to collect data and to maintain schedules for a variety of events. The PLC is provided to allow communications to devices for the purpose of Customer Controlled Load Management either from the Gateway or the SuperStat. It is necessary for the telephony or other WAN to have access to the SuperStat programs under centralized control. This will allow the reading and writing of the program by the Head-End application.

The SuperStat and Gateway support the full range of CEBus communications. All messages will be sent via RF transport. Unsolicited data may be present in the form of alarms and will be accommodated. The Gateway must recognize critical data such as alarms. This will require an alarm list or other means to identify the message as one that needs to be immediately forwarded over the telephony interface.

B.3.6 Outage Monitoring Application

The Outage Monitoring Application will be an option. The following terms and definitions will apply:

• Outage is defined as a power loss greater than XX seconds;

• Power restore is defined as power restoration of greater than XX seconds;

• Momentary outage detection is not part of this offering;

• Power Quality Measurement is not part of this offering;

• Status will be communicated via ANI (automatic number identifier) in the same fashion as the Scientific-Atlanta Locate device;

• Dial tone detection is required with a *** second time out;

• Off hook detection is required for call delay purposes;

• ACK (acknowledge) tone detection is required to acknowledge completed call;

• The Gateway telephony WAN card will make up to Q random attempts to reach the Head-End;

• Standby power of at least *** minutes will be provided.

B.3.7 Gateway Surge Suppression

The surge suppression function suppresses transients in both the ‘differential’ and ‘common’ modes. Typical clamping voltages will be approximately 600 volts at several hundred amperes. After a finite number of transients, the suppressors will reduce their blocking voltage until at some point the devices will support follow-on current from the normal circuit voltage. When this happens, the devices will thermally fail. A fuse will be provided so that a failed suppressor will cause the fuse to open before going into a total self destruct mode. (Total self destruct is defined as burning the leads off to create an open condition.) The optics will detect the open fuse link and cause a call to the Head-End requesting service.

B.4 IN-HOME INTERFACE AND LOAD CONTROL RELAYS

The SuperStatTM system will be the base offering for a customer interface device and in-home controller. SuperStat is a multi-function programmable thermostat that combines the capabilities of a high grade programmable thermostat with a TOU/CTP scheme. Two versions of the SuperStat are available, one for controlling conventional (gas/electric/oil) HVAC systems and the other for controlling heat pumps. Communications between the SuperStat and the Gateway will use CEBus protocol with a two-way RF transport.

B.4.1 Summary of SuperStat Functionality

B.4.1.1 SuperStat Display

1. Red LED flush on front of unit.

2. Indication of device being programmed (i.e. HVAC, water heater, other appliance).

3. Day of week.

e. Override operation during a critical tier will be no different than during any other tier (i.e., a customer will have full temporary and permanent override capability after the onset of a critical price tier).

8. SuperStat will use heat pump intelligent recovery in order to minimize the use of auxiliary heat.

9. The user will not be able to change date, day, or time on the SuperStat.. This information will be kept in the Gateway and updated periodically from the Head-End.

10. SuperStat will display total HVAC runtime since last cleared and HVAC runtime by price tier since last cleared.

11. SuperStat will have battery backup that will retain all programming information in the event of power loss. Maintenance of this battery is the responsibility of the end-use customer.

12. SuperStat will delay *** minutes before restarting a compressor after shutting it off or after a power outage.

13. SuperStat will have a default set of programmed values permanently stored in memory.

On a change in state resulting from either a price tier change or a time period change, SuperStat will signal, via the Gateway, the water heater and appliance load control relays to turn on or off based on the customer’s programmed instructions. SuperStat will also command the HVAC on or off, via existing thermostat wiring, to change measured temperature according to the customer’s programmed instructions. All programs and settings can be entered either by the customer at the SuperStat touchpad or by remote commands from Gulf Power Company’s System Manager through the Gateway.

Price tiers, the correct time, and day of the week will be communicated to the SuperStat from the Gateway.

In the event communications with the Gateway are lost and SuperStat loses its settings, SuperStat will revert to internally stored default settings and will prompt the customer to call for service by displaying Gulf Power Company’s Customer Service Center telephone number.

At all times during which the SuperStat is not being programmed from the touchpad, it will display the current price tier in effect, price bar graph, day, time, program period, temperature, system mode (heat/cool), fan mode (on/auto), and any “holds” currently in effect.

Upon command from the Gateway, the SuperStat will warn the customer of an impending Critical price tier by flashing the display and the red LED until the critical tier takes effect. When the Critical tier becomes effective, the display and red LED will be on without flashing until the Critical tier has ended. When the Critical tier ends the red LED will turn off.

Dear Xx. Xxxxxxxxx and Xx. Xxxxxxx:

This letter is to confirm our conversation about the Gulf Power proposal. Honeywell is prepared to develop an EMS 1000 based user interface/thermostat that we feel meets Gulf’s desires (see attached for features list) and to have production units to stock available in May 1997. As I explained, this only works if Gulf is willing to fund a portion of the R&D in order to move this product forward on our product development roadmaps.

The user interface requirements for this device are complex and work will have to be done to insure that, when all the functionality is available, the device will be easy to use. We will be happy to work with Gulf to determine final approaches to segments, buttons, etc. within the constraints of the device. The constraints are as follows:

· 69 segments 16 keys, 1 LED, glass size: 61mm × 20.6mm, field for segments in glass: 52.8mm × 12.7mm.

In return for the up-front funding, Gulf will receive the following:

1. product designed specifically to meet their requirements,

2. earlier availability of product, and

3. exclusivity as follows: Honeywell will not sell a device in the EMS 1000 product family to other than Scientific-Atlanta or Southern Co. that allows the homeowner to program appliances ( i.e. a water heater and one other device) to respond to time based schedules or changes in rates. Honeywell agrees not to sell this feature or incorporate this feature in any cost - reduced EMS1000 or cost-reduced variations of the EMS1000.

Let me know what additional information I can provide.

Feature Descriptions

Refer to: “LCMs shall be normally closed:

Specification for a time-out feature to be added to the CEBus Load Control Module

A time-out feature will be added to the CEBus Load Control Module (LCM) such that the LCM will reconnect its shed loads automatically after a time-out period has elapsed, when the load has been shed with a CEBus context 57 “off” command. Specifically the following functions will be implemented in the CEBus Load Control Module.

(1) Two new instance variables(one for each relay-drive function), called time-outs, each containing configured values in the range of no less than *** to no more than ***. There should be no value for which the relay would never time out. Gulf Power’s, preference is a *** timeout.

(2) A means of configuring these instance variables over the CEBus network.

(3) Operation should be as follows:

(a) When a relay is commanded to shed load via CEBus context 57, the relay is activated and the time-out variable associated with that load is placed into a down-timer associated with that relay. When that down-timer expires that load is reconnected, even in the absence of a command to reconnect.

(b) If a load is already shed when another shed-command for that load is received, the load remains shed and the time-out instance variable is reloaded into the down-timer, allowing another full time-out period until the load is automatically restored.

(c) If a context 57 “restore” command is received for a load, that load is restored irrespective of the contents of its down-timer. Its down-timer is then cleared.

The thermostat currently Set commands to the LCM, followed by Get commands. The thermostat will now be required to send “Set CEBus context 57 on’ (shed) and ‘Set CEBus context 57 off’ (restore) commands to the LCM. These commands will be sent continuously and will reflect the required state (shed or restore) of the LCM at any given time.

The Set commands from the thermostat to the CEBus Load Shed Relays will need to be routed via the ‘virtual’ LCM’s in the Gateway LAN Card.

Scientific-Atlanta Confidential

Reference to: Thermostat operating in the program mode:

With the current implementation, if the user changes the temperature and raises it above the setpoint, then lowers it below the setpoint, and again raises it over the setpoint, the heal pump will run when the setpoint is raised, it will shut off when it is towered, but it will not run again when the setpoint is raised again or when leaving the programming mode. This occurs because there is a five minute period after turning on the heat pump, during which it will not turn back on. This is to protect the heat pump from damage.

It has been suggested that instead of immediately controlling to the new user settings while in the programming mode, the control algorithm should instead use the old setpoint settings until the user leaves programming mode. This could be achieved in a couple of ways:

• The thermostat could wait for a fixed time-out after the last keypress.

• The user could be required to press “Present Settings” key (or time-out) before the new settings would take effect.

• Or, when the use leaves one programming period to go to another programming screen, could trigger the new setpoints to take effect.

Gulf Power would prefer the functionality provided in the first two bullets. Therefore, user settings would take effect either when immediately when the ‘Present Settings’ key is pressed or *** after the last keypress in the Program mode.

S-A Response:

The thermostat function will be changed to comply with the following:

Any changes made when in the programming mode, will not take effect until the thermostat exits the programming mode.

Scientific-Atlanta Confidential

Reference to: Bar-coding the communications module:

S-A will print a block of labels (as per example label received from Gulf Power) with incrementing numbers.

To minimize handling costs, and serial number tracking in S-A manufacturing:

Units shipped may not be in sequential serial number order.

Serial numbers affixed to non-useable units e.g ‘fall-out’ units due to production yield will not be tracked or reused.

Headend Software:

An additional field is required in the SQL Database table for the new serial number.

An additional field is required in the Application GUI screen for the new serial number.

Gulf Power would prefer the SOCO meter numbering to be sequential if possible. When this is not possible, an Exception Report should be included with the shipment showing which SOCO meter numbers have been omitted.

Refer to: IR Port:

Field Service Utility Application

System Requirements

• Field Computer: Windows 95 based computer (Laptop or Handheld), 000 XXx + Pentium, 32M memory, 100mb disk space for application and work files (one computer required per installation team).

• S-A Infra-red adapter module for Gateway interface port (via Serial port on Field Computer)

• Optional bar-code scanner for device ID entry (interface TBD)

• MFC 4.2 DLL’s installed (S-A to provide per Xxxxx Xxxxxx)

The Field Service Application consists of two major functional modules:

• Basic Installation/Commissioning Functions

• Maintenance and Diagnostics Functions

Basic Installation/Commissioning Functions

Overview

Basic implementation would allow the installer to perform the first-time install of in-home devices, provide device ID’s and customer ID’s for storage at the head-end, and place devices in their initial configuration. The goal is to handle installation of the in-home CEBus devices and Gateway (including multiple thermostats) and verify that all these devices communicate with each other. The installation and verification can be performed without requiring any additional personnel at the head-end during the installation. Customer information such as customer name, address and customer ID will still need to be entered at the Headend via the User Interface or import/export facility. It should also be possible to complete the installation process without requiring the field computer to connect to the head-end in any way.

It is presumed the installer has a work-sheet that indicates customer address, customer ID, and what devices are to be installed. To reduce the likelihood of confusion between devices, it might be necessary to assign device names such as: “Upstairs Thermostat”, “Pool Pump LCM” etc., particularly in the case where multiple thermostats or control devices are being installed. The installer should be able to select from his on-hand inventory, the appropriate devices. Any first-time data, such as initial dial reading, can be entered for forwarding to the head-end. When the in-home installation is complete, the installer then initiates a call-in from the Gateway to the Headend. The Headend Application uploads the data captured at the Gateway, processes this data and updates the database. The results of this processing are then downloaded to the Gateway. After hang-up, the Headend initiates a Gateway summons via the Pager system. The Gateway will subsequently call-in and the Headend will download the TOU schedule, thermostat schedule, offsets etc. The installer can access the PASS/FAIL results data, via the IR interface using the Field Application, prior to departing the installation site. (Gulf Power would like a detailed description and flow chart of this process as soon as available.)

4

Scientific-Atlanta Confidential

The basic installation has limited troubleshooting functions, and does not accommodate the additional processes required for in-home device or Gateway replacement, removal, or addition (these processes are included as part of the Maintenance and Diagnostic Functions module, described later).

MainGate Access (the following functions are part of the In-Field Application software).

• Replace NoAccess layer with the IrAccess interface.

• Implementation of IrAccess interface and porting of the IR protocol from GwCom.

• MainGate Access configuration options and setup utility to select com port and settings.

• New MGA functions to retrieve the serial port status (for showing IR activity)

• New MGA and LAN PT functions to access store-and-forward buffer (SFB) in Gateway

• Use event flag to signal information available in the store-and-forward buffer.

• Modify commissioning process to implement authentication key assignments

• New functions implemented in DevProbe for unit testing

Head-End Software

• Call Handler: Detect flag indicating SFB data available, invoke BgInstall process

• BgInstall: Read SFB data for processing

• Commission gateway to customer for first-time install and update database for actual device ID’s (device records already in database)

• Set initial dial reading, initial pulse count

• BgInstall: Write results back to SFB for future reference.

• Disconnect from gateway, initiate summons. (Will be flagged as no-show if fails to respond to page)

• Subsequent call-in, completes the installation transferring head-end data to the gateway (Thermostat schedule, offsets, load actions, TOU schedule, event rules, WAN broadcast addresses, LCM CLP assignment)

• Additional event log transactions indicate field-service activity.

In-Field Software - First-Time Installation

• Uses MGA in IrAccess mode

• Indicates IR port activity to verify connection status

• Accepts First-time install device parameters: Customer ID, WAN ID (read), LAN ID (read), Tstats ID (entered), LCMs ID (entered). Optional bar-code entry device can be used (Interface TBD)

• Accepts telephony parameters, dial prefix, tone/pulse dialing

• Accepts customer time zone selection

• Accepts initial meter dial reading value.

5

Scientific-Atlanta Confidential

• Accepts name for device (“such as Upstairs” or “pool Pump”)

• Initiates first-time device install: Commission all devices, commission LCM’s to thermostats, commission LAN to thermostats, set configured state of devices, assign authentication keys, set LAN with resulting device addresses and authentication keys, set default thermostat profile (Schedule, load action, offsets), set default WAN profile (dial parameters, dial-in numbers, cap code, group-address (non-configured group or commissioning group since the operational groups have not yet been assigned in the installation process of the gateway)), set default LAN profile (Clock, initial TOU, initial call-in schedule, initial configuration & rules)

• Clears tamper latches, clears com-error flags, clears event log.

• Should get display of the configuration process progress, and information about any failure (which device, failure cause).

• Stores device & customer data in SFB, sets the SFB available flag.

• Initiates a phone-line recalibrate, and sets the call-in flag

• Read SFB state to receive confirmation from head-end (can be done on a return visit).

• Store (or print) audit log of activities performed, results, and errors.

In-Field Software - Troubleshooting

• Retrieve and display current LAN card device configuration (how many, which addresses, current state)

• Retrieve and display current LAN card event flags (tamper, com-error, time)

• Retrieve and display current WAN card flags (tamper, pager reception stats, modern connect state)

• Echo test to CEBus devices and display results (good, bad, no response)

• Query & display LCM relay state.

Maintenance and Diagnostics Functions

Overview

In a complete implementation, additional service functions would be included to accommodate device replacement, removal, or addition. This module would provide an additional notification service by sending a result message, via ‘human’ digital pager, to the Field Service Engineer when the Headend software has completed the installation. The field Service Engineer need not be on-site when the Headend completes the installation.

Also included in the design is a Network Diagnostics head-end UI that queries the database for all gateways (or customers) pending installation, completed installation, or are in some installation failure state.

Additional troubleshooting features include the ability to initiate a live connection with the head end to verify telephony operation, or imitate head-end pages and test sequences. There would also be a more detailed system report, and additional test functions to assist in testing and diagnosing problems.

6

Scientific-Atlanta Confidential

Additional Head-end Software Implementation

• Add/Delete/Modify database records to reflect device changes unknown meter table - to store the dial reading and meter id belonging to the meter being removed

• Resynchronize pulse counter data in database on LAN card reinstall

• Device re-install updates serial number data, clears “valid” flags to insure device is resynchronized with DB.

• Device removal deletes associated device records

• Device addition adds & initializes associated device records

• Reset YTD-CTP accumulator in LAN card from database info when LAN card must be reinstalled.

• Success/Failure message sent to field-service engineers DTMF based pager (BgMonitor function).

• Installation status monitor - reports on the status of pending, failed, or complete installations in the database.

• Live-connect head-end proxy to field computer (for generating pager messages, human alerts, selected DB queries).

In-Field Software - Device replacement / Removal / Addition

• Accept entry of which device is being replaced, and new device ID

• Thermostat/LCM replacement invokes subset of commissioning and authentication assignments for that device, recommissions to LAN card, loads default profile, flags new data in SFB, sets SFB-available flag, initiates call-in.

• LAN card replacement (or pulse encoder type change) requires re-commissioning all devices, and head-end awareness of change in pulse counters and carry-over of YTD-CTP. Very similar to first-time install process.

• WAN card replacement requires in-field reassignment of dial-prefix, tone/pulse, capcode, dial-in number, line recalibration, (perhaps setting GW-ID in EEPROM to previous value?)

Additional In-Field Troubleshooting Functions

• Detailed report of LAN, WAN, and Tstate/LCM device status (essentially all data that can be read) including firmware version, device model information, configuration data, etc.

• Live connect to head-end for testing telephony link, generating pager messages, alerting humans, query customer data, invoking summons sequence, or head-end initiated test process.

• Ability to mute thermostat control of LCMs and provide manual on/off switch operation for testing.

• Ability to load test TOU schedules for thermostat testing (tier changes, CP indication, while LAN uses accumulator zero).

• Ability to query serial number of unknown CEBus devices (presuming ‘promiscuous’ (all-message pass-through) mode available on IR)

• WAN card EEProm access for modifying the Gateway ID

7

Scientific-Atlanta Confidential

Refer to: Gateway must communicate and interface with a minimum of two thermostats:

Constraints:

1) Each thermostat will control one, and only one, dedicated HVAC system. HVAC assignment is made during the CPE commissioning and cannot dynamically change or failover between thermostats.

2) Each thermostat can control up to two CEBus devices designated as ‘Water’ and Appl’. CEBus device assignment is made during the CPE commissioning and cannot dynamically change between thermostats. CEBus devices are individually addressable and cannot be controlled by more than one thermostat.

3) There are no master/slave or peer-to-peer associations or communications between the thermostats. All thermostats work independently and autonomously. The thermostats work as equal but separate CEBus devices relative to the gateway.

4) The thermostats should be individually addressable and should not require common configuration information except for the house code. There should be no dependencies between thermostats for programmed times, temperatures or tier offsets.

Additional for clarification (per home):

Only one TOU schedule

Only one set of accumulators

Both thermostats cannot control the same LCM/Appliance.

Changes required to Support Multiple Thermostats:

Headend Software:

MainGateAccess

• Modify commissioning process to be aware of the second thermostat and LCM’s for node address assignment.

• Extra commissioning steps to commission second thermostat to LAN card and it’s slaved LCMs.

• Additional CEBus addresses and authentication information programmed in LAN card.

• Management of second protocol translator to provide original PT to be compatible with old firmware and a new PT to support the extended functions.

• Above changes cause modifications to the LAN PT, and to DevProve for unit testing.

8

Scientific-Atlanta Confidential

Load Control Application

• Additional target node ID’s for head-end initiated DLC function (extra broadcast for second thermostats)

BgInstall Process

• BgInstall/BgDiagnostic manage the upload and download of thermostat schedules. When the customer changes a schedule in the thermostat (not including temporary or permanent holds), it is uploaded to the database during the next call-in. (This call-in is selectable and can be instantaneous, first available night or during the monthly meter read). If head-end activity modifies a schedule (or re-assigns the default) the schedule is downloaded to the thermostat on the next call-in. This process has to be aware of two thermostats, and two database entries.

• BgInstall also needs to be aware of multiple LCM’s when it comes to configuring the CLP and address values.

• BgDiagnostic also has to recognize the presence of additional devices when reporting errors such as com-failure.

Database and UI

It will be important to include a device description field (such as “upstairs” or “downstairs”) to identify the devices. These values can be assigned by the field-installation application when the device is actually installed.

LAN Firmware

The LAN firmware will need to maintain communications with each thermostat individually. It will need to manage configuration parameters for all thermostats associated with a given Gateway. Similarly, event logging, error logging, communication required rules etc. will need to be maintained for each thermostat.
