GF83.10-P-2102-02T Blower, Function

Function
The AAC [KLA] control and operating unit (N22) or comfort automatic air conditioning (N22/7) passes on a control voltage of 0 % to 100 % to the blower regulator (A32n1) via climate bus 1. Depending on the control voltage applied this then regulates the operating voltage for the blower motor (A32m1). This achieves a control of blower speed from 0 % to 100 %.

The blower regulator (operating voltage) is influenced by the following factors:
^ Blower output adjustment (AUTO/manual)
^ Operating functions (AC OFF, REST, air distribution)
^ Mode status (heating, cooling)
^ Intensity of sun
^ coolant temperature
^ Vehicle speed
^ Outside temperature
^ Humidity
^ Fresh air/recirculated air flap setting
^ Position of activated carbon filter flap
^ Flap positions
^ Terminal 15 (blower ON), starter running (blower OFF)
