Service Manual Switching the freezer compressor on and off depends on the external NTC sensor (environment). 5.1.3 Superfrost function Pressing the T8 button will activate the superfrost function with which the compressor is supplied consistently for 54 hours. In order to deactivate the function, the T8 button must be pressed again before the 54 hours have lapsed.

Service Manual 5.1.8 Refrigerator controls The compressor is activated when both the external NTC sensor (environment) and the NTC sensor for the evaporator measure the switch-on temperature. It is switched off when the temperature measured by the external NTC sensor (environment) reaches the switch-off temperature. The interval time of the compressor may be extremely long if the room temperature is low.
Service Manual 3/4 star compartment The combination bi-compressor refrigerator is only illustrated with electronic controls. Buttons T1 = ON/OFF refrigerator L1 = Refrigerate ON/OFF (green) T2 = Increase in temperature L2 = Rapid-cool function (yellow) T3 = Decrease in temperature L4 = Superfrost function (yellow) T4 = Rapid-cool function T8 = Superfrost function...
Service Manual 5.2.2 Equalizing resistance with an automatic switch-on device (3/4 star compartment) The 3/4-star compartment model is equipped with an equalizing resistance device which switches on automatically if the NTC sensor (S) on the electronic module measures a room temperature of less than +24°C.
Service Manual Freezer display The functions, buttons and LEDs are the same as those of the combination bi-compressor. Symbols “+39” – “–35” constant light: display of the average temperature in the freezer “–15” – “–24” blinking light: display while adjusting the temperature; display switches off 5 seconds after completion of setting “+39”...
Service Manual NTC sensor failure The NTC sensors have the following temperature resistances: 10 000 9000 8000 7000 6000 5000 4000 3000 2000 1000 –40 –30 –20 –10 Temperature (°C) The electronic unit considers abnormal resistance levels to be a sensor failure. A symbol appears on the display.
