Common use of CONTROL WORK Clause in Contracts

CONTROL WORK. Control work shall include building standard Alerton BACnet pressure-independent digital zone controllers with heating coil discharge air temperature sensors, MicroSet wall thermostats with display and buttons, UL Listed 24 VAC, 40 VA transformer, Belimo damper actuators, Belimo PICCV control valves with actuators, installation, programming and graphics/alarm/trend updating at operator workstation. i) Tie zone controllers into the existing floor MS/TP BACnet data network at the main ducts. Insert the tenant zones into the network by pulling network cable back to the adjacent zone and running new wire to the new zone, then picking up the existing wire again to form a daisy chain with no intermediate splices. (1) Program zone terminals identically to the base building terminals including feedback for static pressure reset, discharge air temperature reset with heating minimum air flow reset, purge-out, warm-up/cool-down, demand controlled ventilation and other building standard control features. (2) Program the perimeter zones and gathering areas for a minimum air flow of 20% of design flow and interior open areas to zero minimum flow. All zones shall accept proportional reset from demand controlled ventilation algorithms. ii) Provide Telaire Model 8003 CO2 sensors in tenant spaces for sensing the average CO2 levels. Provide additional sensors in lunch rooms, conference rooms and other closed areas where more than four people can gather. (1) Program each zone to accept digital reset of the minimum air flow setting from the CO2 sensors in the related spaces. Where a CO2 sensor encompasses several related zones, link these zones to the demand controlled ventilation reset. Reset the minimums proportionally up to 40% of design flow in each zone.
