GF83.57-P-2000GI Temperature Control, Function
- with CODE (580a) Automatic air conditioning

Function
The electronically controlled cooling, heating and ventilation system of the automatic air conditioning achieves the desired in-car temperature as rapidly as possible or maintains it constantly. The following options are available for this purpose:
- the evaporator cooling the air
- the heating system heat exchanger heating the air

Temperature control
The temperature values needed for the temperature control are determined by the in-car temperature sensors (N22b1), center nozzle air stream (B10/24), footwell at front (B10/25), rear (B10/7), outside temperature indicator (B14) and defroster protection (R35). The electronics of the AAC pushbutton control module (N22) compare the various test values with the temperature preselected at the temperature selector wheel.

As required, the automatic air conditioning performs the regulation in that in heating mode it controls the position of the blending air flaps, via the blending air flap actuator motor (M2/6), or in cooling mode it actuates the refrigerant compressor and thus keeps the respective setting constant.
