Fan Fan control
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.
F04 FanStopTemp.
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
F05 FanPulseMode

Defrost start, minute setting (1 and 11 belong together, etc.)
When all t01 to t16 equal 0 the clock will not start defrosts.
t11-t16
Real-time clock::
Setting the clock is only necessary when there is no data communication.
In the event of a power failure of less than four hours, the clock function will be saved.
