Defrost start
Defrosting can be started by two methods:
S
Internal timer
The next defrost cycle cannot be started before the safe defrost time (defrost parameter) has expired
even when defrosting is terminated by evaporator temperature.
Defrost times should preferably not be set between 02:00 and 03:00 hours so as to avoid problems
of missed or duplicated defrosting when the clock changes to or from daylight saving time.
S
Command via CAN bus (manual command, PC software command)
In every instance, the controller checks whether conditions for defrosting are fulfilled before defrosting is actu
ally initiated. These conditions are:
Evaporator temperature lower than defrost termination temperature
With demand defrosting, defrost counter at 1 (UR 141)
