Blower controller function - GF83.10-P-2103-01Q

Function 

The AAC [KLA] control and operating unit (N22) (on vehicles without code (581b) comfort automatic air conditioning) or the comfort AAC (C-AAC [K-KLA]) control and operating unit (N22/7) (on vehicles with code (581b) comfort automatic air conditioning) forwards a control signal of between 0% and 100% to the blower regulator (A32n1) via the A/C bus. This regulates the output of the blower motor (A32m1)and thus the flow rate of the air drawn in or the recirculated air.

The blower regulator is influenced by the following factors:

• Blower preselection on the AAC [KLA] control and operating unit (N22) or the comfort AAC (C-AAC [K-KLA]) control and operating unit (N22/7)
• Preselection of air distribution
• AC OFF function active
• Engine residual heat utilization function active
• Recirculated air function active
• Temperature preselection
• Coolant temperature
• Outside temperature
• Vehicle speed
• Flap positions of actuator motors
