Temperature control, function - GF83.57-P-2000GI
MODEL 163 as of 01.09.01 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 push-button 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.
