GF83.30-P-2105-02GH Fresh Air/Recirculated Air Flap Actuator Motor, Function
GF83.30-P-2105-02GH Fresh Air/Recirculated Air Flap Actuator Motor, Function
Function
The fresh air/recirculated air flap actuator motor (M39) is controlled via the recirculation air switch and when the temperature selector switch is set to
max. cooling output in the control module (S98).
Recirculated air mode (100 % recirculated air)
In the recirculated air mode the supply of fresh air is closed by the fresh air/recirculated air flap actuator motor (M39) and simultaneously the
recirculated air supply opened without any time limit.
Fresh air mode (100 % fresh air)
In the fresh air mode the supply of fresh air is opened by the fresh air/recirculated air flap actuator motor (M39) and simultaneously the recirculated air
supply closed without any time limit.
Auxiliary function at air conditioning (TAC)
When, in the cooling mode, the temperature selector wheel is set to max. cooling (position indented blue) then at the same time the fresh air/recirculated
air flap actuator motor (M39) is controlled and switched to recirculation air without time limit.
