Operating functions. Off • In this mode, the thermostat will not turn on the heating or cooling devices (manual fan can operate). • Off is also used to access Configuration mode. > < Cool • In this mode, the thermostat controls the cooling system. • Press the or button to set the desired temperature. 10 > < Heat • In this mode, the thermostat controls the heating system. • Press the or button to set the desired temperature.
Testing the thermostat. Once the thermostat is installed, it should be thoroughly tested. CAUTION! Do not use air conditioning beyond the simple test when the outdoor temperature is below 50 degrees. This can damage the air conditioning system. Note: Before testing the thermostat, move the Fan Auto/On switch to the Auto position. Fan Test 1. With Function switch set to Off, slide Fan Auto/On switch to On position. 2. Indoor fan turns on. 3. Slide Fan Auto/On switch to Auto position. 4.
Testing the thermostat. Heat Test 1. Slide Function switch to Heat position. Heat mode screen is displayed. 2. Adjust set temperature so it is 5 degrees above room temperature. 3. Heat should come on within a few seconds. 4. Adjust the set temperature so it is 2 degrees below the room temperature and the heat should turn off. Note: There is a 3 minute time delay and a 3 minute minimum run time for the compressor when it turns on/off. (On some models, the fan may also have a minimum run time/off time delay).
Troubleshooting tips. Problem Solution No display Check for 24 VAC; display is blank when 24 VAC is not present. System fan does not come on properly Verify that wiring is correct. All thermostat buttons are inoperative Verify that 24 VAC is present; unit will not operate when 24 VAC is not present Thermostat turns on and off too frequently Adjust temperature differential (see Configuration Mode - Setting Temperature Differential, Stage 1 and Stage 2 sections).
