PARAMETERS 

CC - Select Cooling Cycle Rate   

The FA setting produces shorter cooling cycles. The SL setting produces longer cooling 
cycles. FA cycles the system at a 0.75ºF differential (0.5°C), and SL cycles the system at a 
1.5ºF differential (1°C).   

HC - Select Heating Cycle Rate   

The FA setting produces shorter heating cycles. The SL setting produces longer heating 
cycles. FA cycles the system at a 0.75ºF differential (0.5°C), and SL cycles the system at a 
1.5ºF differential (1°C). 

CP - Select Compressor Lockout Delay 

To protect the compressor from short cycling, you can select the minimum length of time the 
compressor will turn off between cycles from 0 to 5 minutes in 1 minute increments. When a 
compressor lockout delay occurs, “COMP DELAY” will flash.
