Function: This parameter is used to set the frequency for
Defrost Cycle for Compressor2.
This is the amount of time between two Defrost Cycles.
Example: As explained for P72 Parameter.
Note:
• This parameter is not considered if CS = C1.

Function: Power ON Defrost Delay for Compressor1.
This parameter is used to set Defrost Delay at Power ON.
This delay starts once the controller is Powered ON. Once
this time delay gets over and if conditions are not suitable
for Defrost, means, Control Probe Sensor is Faulty,
defrost will not take place, but the time calculation does
not get cleared, it will clear only when Defrost takes place.
And Defrost take place once the conditions become
suitable for Defrost.

Function: Power ON Defrost Delay for Compressor2.
P92 parameter is used to set Defrost Delay at Power ON.
