Fan
Fan stop temperature
The function stops the fans in an error situation, so that they will not provide power to the
appliance. If the defrost sensor registers a higher temperature than the one set here, the
fans will be stopped. There will be re-start at 2 K below the setting.
The function is not active during a defrost or start-up after a defrost.
With setting +50°C the function is interrupted.
Pulse operation of fan
0: No pulse operation
1: Pulse operation when the thermostat does not call for refrigeration
2: Pulse operation when the thermostat does not call for refrigeration, but only during
night operation
Pulse operation period for fan
Here the overall pulse time is set. The sum of ON-to and OFF time.
ON time for fan
Here the % part of the period the fans are to be in operation is set.
The LED on the controller's front will indicate whether a defrost is going on.

(Not used if an external defrosting schedule is used via data communication.)
Up to six individual times can be set for the defrost start throughout the day.
