Function
The C-AAC sun sensor (4 in total) (B32/2) records the intensity and angle of incidence of the solar radiation on the vehicle.
This enables the in-car temperature and blower speed to be automatically adapted depending upon the level of radiation intensity (brightness).
Moreover, where radiation is of a one-side nature, then a suitable temperature difference is automatically set between the right and left regulated specified temperatures.
The measured value is forwarded to the comfort AAC control and operating module (N22/7).
