SUNLOAD Sensor

The sunload sensor is mounted in the center of the instrument panel upper surface. The sensor contains a photoelectric cell, which provides the CJB with an input of light intensity equating to the solar heating effect on the cabin.

The solar heating value is transmitted from the CJB to the ATC module over the medium speed CAN bus. The ATC module compensates for the solar heating effect by adjusting blower speed, air output temperature and air distribution to maintain the required cabin temperature.
