Condensate drain heater (par. DOP)
During defrosting there may be frozen condensate on the bottom of the cabinet that prevents the water thawed from the
evaporator from being drained correctly. The digital output can be configured to manage the condensate drain heater function.
The heater is started on activation of the pump down stage and stays on throughout the defrost procedure, until the end of the
dripping phase. The heater can be activated by selecting a digital output with par. DOP.
Notice: the heater must be protected against overheating (e.g. thermal protector).
