Once the thermostat is installed, it should be thoroughly tested.

NOTICE 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 Speed switch to High, and slide Fan Auto/On switch to On position.

2. Indoor fan turns on in high speed. 3. Slide Fan Speed switch to Low. 4. Indoor fan slows to low speed. 5. Slide Fan Auto/On switch to Auto position. 6. Indoor fan turns off.

Cool Test 1. Slide Function switch to Cool position. Cool mode screen

is displayed. 2. Adjust set temperature so it is 5 degrees below room

temperature. 3. Air conditioning should come on within a few seconds. 4. Adjust the set temperature so it is 2 degrees above the

room temperature and the A/C 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).
