- except 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 interconnected 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. 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 blend air flap actuator motor (M2/6), the right blend air flap actuator motor (M2/7), the left and right footwell flaps actuator motor (M2/15), the left and right defroster flaps actuator motor (M2/16), the fresh air flaps actuator motor (M2/21) for the air distribution and the blower motor (A32m1) for the air volume are controlled by the AAC [KLA] control and operating unit (N22) via the A/C bus (KB).

On model 209.4, the blower actuation 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/b1) in the AAC [KLA] control and operating unit (N22) 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)
^ Air humidity through the air humidity sensor (B31/2) (up to 28.6.06)
^ On-board power supply via the EIS [EZS] control unit (N73)
^ Outside temperature via the outside temperature display temperature sensor (B14)
^ 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)
