The thermostat shall have a minimum deadband of 2°F (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. C. 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 Unoccupied Heating Setpoints 70°F (21°C) 55°F (13°C) Cooling Setpoints 75°F (24°C) 85°F (29°C) D. SETPOINT RECOVERY FROM UNOCCUPIED TO OCCUPIED: 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). E. FAN OPERATION: For Heat pump or Conventional modes: a. On: Fan operates continuously in Occupied mode, and during a call for heat or cool in the Unoccupied mode. Uses the G fan relay. b. Auto: Fan is energized with calls for heating and cooling. Uses the G fan relay. For PTAC and Fan coil modes: a. Lo, Med, Hi (Fan Coil), Lo, Hi (PTAC): Fan operates continuously in Occupied mode, and during a call for heat or cool in the Unoccupied mode. Uses the G, G2, G3, fan relays. b. Auto: Fan is energized with calls for heating and cooling. Auto uses the fan ramping algorithm to automatically select the correct fan speed c. PTAC and Fan Coil modes can be configured for Auto only, constant fan speed only (Lo, Med, Hi), or both. d. Auto Fan Reset: Set the fan from a constant fan speed (Lo, Med, Hi) to Auto after 2 or 4 hour time period. Saves energy and fan usage. (optional feature) F. MINIMUM STAGE OPERATION TIME: a. Minimum On: Heat - 1 minute; Cool - 3 minutes. b. Minimum Off: Cool & Heat Pump - 1 minute. G. POWER INTERRUPTION: 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. H. OVERRIDES: a. The Override button 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 Holiday 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. d. Remote Setback input terminals can be used to operate the thermostat in either Occupied or Unoccupied mode (non-programmable mode only). 63-2676—03 2 TB7100A1000 MULTIPRO™ MULTISPEED AND MULTIPURPOSE THERMOSTAT CONFIGURATION OPTIONS 1.

In the programmable schedule mode, an override button is available for temporary override control. The default override time can be configured through the installer setup. b. Thermostat can be configured as a non-programmable thermostat. Remote setback feature is available in the non-programmable mode. 3. Preoccupancy Purge a. This feature is available only when the thermostat is configured as a programmable schedule and when a fan is used. The fan will run 1-3 hours before the occupied schedule starting time to circulate air. 4. Remote Setback a. Remote Setback is available in the non-programmable mode. Occupancy sensors, manual time clock inputs, and DDC night setback can be used to provide inputs to setback the thermostat. Unoccupied heating and unoccupied cooling setpoints are available to configure the setback setpoints. 5. Lockout a. Lockout configurations are optional and can provide restrictions on access to setpoint, system, schedule, and fan changes. THERMOSTAT MODELS AND FEATURES Table 2. TB7100A1000 Thermostat Features.
