GF83.40-P-2006Q Regulation Of Comfort Automatic Air Conditioning, Function
- with CODE (581) Comfort automatic air conditioning

Component Identification:

Function
All the control units which fulfill a task in the control of the automatic air conditioning are connected to each other via the CAN-B (CAN-B). The CAN-B (CAN-B) is a bidirectional bus, i.e. each connected control unit is capable of sending and receiving information.

The electronics for regulating the automatic air conditioning are networked with the entire vehicle electronics via CAN-B (CAN B). This in turn makes it possible to incorporate additional climate- relevant influences, in order to improve the regulation quality and to lower power consumption.

The fresh air/air recirculation flaps actuator motor (M2/5), the left blending air flap actuator motor (M2/6), the right blending air flap actuator motor (M2/7), the left defroster vent flap actuator motor (M2/8), the right defroster vent flap actuator motor (M2/9), the left footwell flap actuator motor (M2/10), the right footwell flap actuator motor (M2/11), the left fresh air flap actuator motor (M2/19), the right fresh air flap actuator motor (M2/20), the activated charcoal filter flap adjustment motor (A32m2) for the air distribution and the blower motor (A32m1) for the air volume are controlled by the comfort AAC [KLA] control and operating unit (N22/7) via the A/C bus (KB) .

On model 209.4, the blower output is increased linearly during driving with open soft top in automatic mode depending on the speed up to a factor of 1.3 at 100 km/h.

The following is available for the electronic control and regulation of interior temperature, air quantity and air distribution ducts:
^ Interior temperature via the in-car temperature sensor (N22/7b1) in the comfort AAC [KLA] control and operating unit (N22/7) and on vehicles as of 1.6.05 additionally via the in-car temperature sensor (N70b1) in the overhead control panel control unit (N70)
^ Position of the windows via the left front power window motor (M10/3), the right front power window motor (M10/4), the left rear power window motor (M10/5) and the right rear power window motor (M10/6)
^ The air humidity and the concentration of pollutants via the C-AAC [K-KLA] multifunction sensor (B31)
^ On-board power supply via the EIS [EZS] control unit (N73)
^ Outside temperature via the outside temperature display temperature sensor (B14)
^ Intensity and angle of incidence of the sun rays via the CAAC sun sensor (4 in total) (B32/2)
^ Ground speed via the instrument cluster (A1)
^ Pressure and temperature of the refrigerant over the pressure and refrigerant temperature sensor (B12/2).
^ Temperature on the evaporator via the evaporator temperature sensor (B10/6)
^ Soft top status via the power soft top control unit (N52) (on model 209.4)
