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

CAUTION!

Do not energize the air conditioning system when the outdoor temperature is below 50 

degrees. It can result in equipment damage or personal injury.

Cool Test

1.  Slide 

Mode

 switch to 

Cool

 mode.  

2.  Adjust set temperature so it is 5 degrees below room temperature. 
3.  Air conditioning should come on within a few seconds. Status indicator may come on.
4.  Adjust the set temperature 2 degrees above the room temperature and the A/C should 

turn off.  There may be a fan delay on your system.

 

 

Note:

  There is a five minute time delay to protect the compressor after it turns off. To temporarily 

bypass the five minute delay, slide the 

Mode

 switch to 

OFF

 for 2 seconds and then back to 

Cool

.
