2. Mount thermostat base to wall Remove the back plate from the thermostat. 4. Attach the thermostat to back plate Align the 2 notches at the top of the base plate with the holes on the top of the thermostat then rotate on the hinge point down to close. Secure the thermostat back plate to a 2 x 4" electrical box with machine screws or to drywall using wood screws with wall anchors. 5.
Equipment Connections This illustration shows various equipment connected to the HVAC Interface Module. Other equipment may be included in your application.
Wiring the HVAC Interface Module Ensure power to connecting equipment is off. To prevent the risk of personal injury and/or death, make sure power is not applied to the thermostat or HVAC Interface Module until they are fully installed and ready for configuration. All work must be done with power to the circuit being worked on turned off. The HVAC Interface Module includes three relay power jumper connectors. These are used to provide power between terminals when necessary.

Sequence of Operation Heating and Cooling Operation • The Heat On symbol is shown on the display when the thermostat is heating. • Heating for freeze protection is provided whenever the air or floor temperature falls below 40°F (4.5°C), regardless of operating mode. •T he Cool On symbol is shown on the display when the thermostat is cooling. The thermostat supports two heating system types: 1) conventional, or 2) heat pump.
When radiant floor heating is installed, it is always the first stage of heating, followed by the heat pump, and lastly any backup heating. This allows the floor to remain warm in the heating season.
Cooling Differentials The first and second stage cooling have adjustable differentials and time delay setting to determine when the stage turns on, and shut off when the room temperature reaches 0.5 and 0.0°F (0.25 and 0.0°C) above the Cool To setting respectively. Heat Pump Balance Point An air source heat pump’s Coefficient of Performance (COP) declines with falling outdoor air temperature.
Relative Humidity Operation Relative Humidity Sensor The thermostat includes an internal relative humidity (RH) sensor and has the option to connect to an external RH sensor. The installer has the option to disable the internal RH sensor when an external RH sensor is installed. When both the internal and external RH sensors are enabled, the RH reading is averaged. Humidifier Operation The thermostat controls the relative humidity (RH) by operating either the Accessory 1 or Accessory 2 relays.
Error Messages Description COMMUNICATION ERROR Communication between the display module and the HVAC Interface Module is interrupted. This error clears automatically once communication is re-established. This error can occur if the power supply voltage to the HVAC Interface Module is low. Check the voltage with a volt meter and that the transformer VA rating is enough to power all the equipment. MEMORY ERROR The thermostat memory settings are corrupted.
Description WATER LEAK DETECTOR WARNING A water leak has been detected and the water line has been shut off. The warning will automatically clear once the water leak detector has been reset. ROOM HOT WARNING The room temperature is above the Room Hot Warning setting in the Alerts menu. The warning will automatically clear once the room temperature falls below the setting. ROOM COLD WARNING The room temperature is below the Room Cold Warning setting in the Alerts menu.
