Rear compartment blower
The rear compartment blower enables infinitely variable adjustment of the blower output and of the temperature in the rear compartment. A coolbox is also operated based on the setting of the temperature control wheel.

The voltage tapped off at the potentiometer is in the range from 1.25 V to 5 V. The voltage tapped off at the rear compartment blower potentiometer is amplified in the IHKA control module and supplied to the output stage for the rear compartment blower motor. The control voltage is between 0 V... 8 V.
