3.7 Winter switch
For ambient temperatures of 0 °C to 17 °C, heat input in the refrigerator compartment
decreases and compressor runtime is reduced.
As a result, the temperature in the freezer compartment can rise and defrost the
freezer compartment. Winter switch prevents this and maintains a temperature of -18
°C in the unregulated freezer compartment.
Winter switch heats the refrigerator compartment and thus makes sure the compressor
switches on early.
Winter switch can be actuated manually via a switch or automatically.
There are two options for warming up:
¡ Interior lighting of the appliance,
¡ Foamed refrigerator compartment heater.

With an automatic winter switch, the heater is on permanently when the ambient tem-
perature is below 17 °C. When the ambient temperature is between 17 °C and 21 °C
the heater is activated in the off period of the compressor cycle.
