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

Function 

The desired in-car temperature is set by turning the temperature selector wheel on the AAC push-button control module (N22).

The AAC push-button control module (N22) compares the desired temperature with the temperature in the passenger compartment. The passenger compartment temperature is determined by the in-car temperature sensor on the AAC push-button control module (N22) and the temperature sensor for the vent air at the center nozzle, front and rear footwells.

Using the comparison between specified and actual values, the AAC push-button control module (N22) determines the correct setting of the blending air flaps and actuates these. The selected temperature is reached and maintained as quickly as possible, if warming or cooling of the interior is necessary.
