Description and Operation

Description

The photo sensor is located in the center of the heater vents.

The photo sensor contains a photodiode that responds to sunlight. Solar radiation generates an electromotive force proportional to the amount of solar radiation received. It is connected to the air conditioning control unit, which compensates for the intensity of sunlight in the climate control.
