Testing Guarantee Service:
Prior to installation, the contractor shall provide copies of submittals. The contractor is responsible for assuring that conduit and wire quantity, size, and type are suitable for the equipment supplied. Upon completion, the contractor shall conduct a total system test for the owner and engineer. All components, parts, and assemblies supplied by the manufacturer shall be guaranteed against defects in materials and workmanship for 5 years. Warranty service shall be performed by the contractor.
SEQUENCE OF OPERATIONS
The heating and cooling setpoints shall be individually adjustable for both the Occupied, Unoccupied and standby periods. The thermostat shall have a minimum deadband of 2F (no mechanical heating or cooling shall operate within this deadband). Space temperature deviation above the cooling setpoint or below the heating setpoint shall generate a demand signal to control the system as follows: A. Heating: The thermostat shall control the heating output based on the demand signal communicated from the thermostat program, taking into account both space temperature deviation (proportional gain), the duration of that temperature deviation (integral gain). The thermostat shall energize heating equipment when space temperature falls below heating setpoint. B. Cooling: The thermostat shall control the cooling output based on the demand signal communicated from the thermostat program, taking into account both space temperature deviation (proportional gain), the duration of that temperature deviation (integral gain). The thermostat shall energize cooling equipment when space temperature exceeds cooling setpoint. (Optional Remote Equipment) A solid state enthalpy changeover control shall determine the capability of the outdoor air to provide free cooling (optional). The system shall operate as follows: a. Free cooling available from Outdoor Air: On a call for cooling, the system shall enable the economizer to provide free cooling. If this does not meet the space demand, the system shall call for mechanical cooling to satisfy the programmed setpoint. b. Free Cooling Not Available From Outdoor Air: On a call for cooling, the system shall hold the economizer to minimum position and cooling shall be energized to satisfy the programmed setpoint. C. Economizer Interface: The auxiliary output of the subbase shall be connected to the economizer's power circuit or the Occupied/Unoccupied signal terminal. a. Occupied Period: The auxiliary output will provide 24 Vac, allowing the economizer to operate normally and be available for free cooling if outdoor conditions permit. b. Unoccupied Periods: The auxiliary output will cease, defeating either economizer operation or the minimum position. Heating Setback and Cooling Setup: Initiation of heating setback or cooling setup for each of 7 days shall be provided by a programmed time schedule manually entered into the thermostat. When all or a portion of a manually programmed schedule is unavailable, the thermostat shall control to the default program as shown in Table 1. Table 1. Default Program. Occupied Heating Setpoints Cooling Setpoints E. Setpoint Recovery from Unoccupied to Occupied: 70F (21C) 75F (24C) Unoccupied 55F (13C) 85F (29C)
The thermostat shall incorporate a ramping feature that gradually changes the space setpoints. During recovery operation, the setpoint changes at a rate in degrees per hour (defined in the Installer Setup Menu).
Fan operation shall be selectable as follows: a. On: Fan operates continuously in Occupied mode, and during a call for heat or cool in the Unoccupied mode. b. Auto: Fan is energized with calls for heating and cooling. a. Minimum On: Heat - 1 minute; Cool - 3 minutes. b. Minimum Off: Cool & Heat Pump - 1 minute. a. On loss of power, the thermostat shall maintain programmed times and temperatures for 10 years. b. Clock and day information shall be retained for a minimum of 2 years. a. The Holiday Override can be used when the thermostat is in Unoccupied mode. It shall switch to the Occupied mode for an installer-configured number of hours. b. The Temporary Unoccupied Override shall fix the schedule to operate in Unoccupied mode for a number of days (between 1 and 365) without changing programming saved in memory. c. Pressing Cancel or Run Schedule shall cancel the overrides and return to the program.
