Temperature selector wheel, function - GF83.25-P-2102-01GH

Function 

Heating 

By rotating the temperature selector wheel, a cable is moved via a disk cam, thereby actuating the blending air flaps.

Air conditioning 

The air temperature is regulated by a rotary control with a variable resistor. Signals from the resistor and AAC control module determine the desired interior temperature. If the temperature selector wheel is turned in an anti-clockwise direction to the final indented position (max. cooling), the recirculation switch is bypassed and thus the fresh air flaps closed, in order to achieve the max. interior cooling (with A/C ON).
