Protects the Outdoor coil from ice formation by controlling COMP & RV operation.

 Scope

 

This new deicer is designed to operate at extreme temp conditions.  The deicing cycle    

could be triggered from:

 

1. OCT temp and time between two consecutive deicing cycles.

 

2. Detection of ice forming by change of the OCT temp.

 

Both algorithms adjust the time between deicing cycles to optimize the A/C  

 

 

 

performance. The algorithm will automatically increase the time between deicing cycles    

and reduce the deicing cycle as needed.

 

The algorithm uses EEPROM data to operate.
