Function 

With AAC  a control voltage (0-6V) is transmitted to the blower regulator via the blower knob ( BLOWER BUTTON ) or in the automatic mode via the AUTO button ( AUTO BUTTON ) with the AAC pushbutton control module.

Depending on the control voltage it then controls the operating voltage for the blower, regulating the blower speed within the range of 0 - 100 %.

In the manual mode actuation is subdivided into 7 stages (segments). The possible control voltages for the air conditioning (AAC) are listed in the table below.

Blower stage on display (segments) Control voltage ranges (Automatic mode) Control voltages (Manual mode)
1st segment min. 0.8 V 0.8 V
2nd segment >0.8 V up to 1.1 V 1.0 V
3rd segment >1.1 V up to 1.8 V 1.5 V
4th segment >1.8 V up to 2.8 V 2.3 V
5th segment >2,8 V up to 3.5 V 3.2 V
