The thermostat controls the cooling system. FAN Switch Auto: On: The fan only runs with the heating and cooling system. The fan runs continuously. Use for improved air circulation. CHECKOUT NOTE: Temperature setpoint range is 40°F to 90°F (4°C to 32°C) in heating and 45°F to 99°F (7°C to 37°C) in cooling. Heating 1. Slide the SYSTEM switch to Heat and the FAN switch to Auto (T8775C only). 2. Raise the temperature setpoint several degrees above the room temperature. 3. A flame will appear in the display and the heat should turn on. 4. Lower the temperature setpoint below the room temperature. 5. The flame will disappear from the display and the heat should turn off. Cooling (T8775C only) CAUTION Low Temperature Hazard. Operating at too low of an outdoor temperature may cause compressor damage. Do not operate cooling if outdoor temperature is below 50°F (10°C). Refer to manufacturer's recommendations. NOTE: If a call for cooling is made before the compressor has been off for five minutes, or if a power interruption occurs while the compressor is running, the thermostat will go into a five-minute delay to protect the compressor. The snowflake will flash during this delay. 1. Slide the SYSTEM switch to Cool and the FAN switch to Auto. 2. Lower the temperature setpoint several degrees below the room temperature. 3. After approximately five minutes, the thermo- stat will display a solid snowflake and the cooling should turn on. 4. Raise the temperature setpoint above the room temperature. 5. The snowflake will disappear from the display and the cooling should turn off. Fan 1. Slide the SYSTEM switch to Off and the FAN switch to On. The fan should run continuously. 2.
