Always 

de-energized when “Cool” switch is selected on thermostat.

Compressor operation:    

If ambient indoor temperature is above set point temperature depending on t-stat differential and 

the compressor is not time delayed, turn on compressor.  If ambient indoor temperature is

below set point depending on t-stat differential, turn off the compressor. 

 

Compressor time delay:  

The 

time delay feature is de-energized for a period of time that varies randomly from 180 to 

240 seconds. Compressor time delay is initiated every time the compressor is 

“off” due to:  

(1) Satisfying the temperature set point,   
(2) Changing mode to fan only    
(3 )Turning the unit off.    
(4) Control is first energized or when power is restored after failure  

Note: Time delay is disabled during Test Mode.  
Indoor coil frost protection (Error Code 07):  

While in cool mode: If the indoor coil frost protection sensor reads 

30°F for 2 minutes continu-

ously, 

turn off the compressor, but continue fan operation. While the compressor is out and the 

fan is running: when the indoor coil frost protection sensor reaches 

45°F, turn on the compres-

sor. However, the compressor must still wait a standard time of 

180 to 240 seconds. While 07 

flash, heat  operation is disabled.  

Fan delay:   

This is only for 

fan ‘cycle’ mode and not for fan ‘continuous’ mode.  When unit  cycles cool-

ing ON – start the fan 5 seconds EARLY. When unit cycles cooling OFF –  DELAY the fan off 

for 30 seconds.  Note: the fan delay is disabled during 

Test Mode.  

Reversing valve:  Always de-energized when “Heat” button is pushed. 

 

Compressor operation: Compressor does not operate in this mode.

Electric heat operation:  If temp is below set point, depending on t-stat differential, turn on 

electric heat. If Ambient is above set point depending on t-stat differential, turn off the electric 

heat.  

Fan delay:  This is only for fan ‘cycle’ mode and not for fan ‘continuous’ mode.  When unit  

cycles heating 

ON – start the fan 5 seconds EARLY. When unit cycles heating OFF – DELAY 

the fan off for 

15 seconds. Note: the fan delay is disabled during Test Mode.
