- with CODE (580) Automatic air conditioning
Function
The dew point sensor (B11/12) measures the humidity of the air that is drawn in and relays this measurement to the AAC control and operating unit
(N22). The AAC control and operating unit (N22) uses this measurement to control the air drying in order to achieve a pleasant interior climate that is
not too dry. The refrigerant compressor (A9) is actuated to do this.
The air in the evaporator is only cooled down to the level required in the passenger compartment. Reheating only takes place if this function is required
to defog the windows.
