Functional Description Solar Sensor For IHKA

Functional description solar sensor for IHKA

As part of climate control, the solar sensor takes into consideration external light and heat sources that influence the climate in the vehicle interior. The solar sensor consists of one Photo-resistor that measures the varying intensity of solar radiation. At high levels of solar radiation, the setting of the air conditioning system is correspondingly adapted to requirements.

The following settings are varied:

Blower - The blower curve is changed

Stratification - The stratification air temperature is changed

Ventilation flaps - The angles of the ventilation flaps are changed

The signal of the solar sensor is generated in the solar sensor module. The sensor signal is output in a voltage range of 0....5V. A value outside the limits indicates a malfunction and the influence of the sensor is completely suppressed.

Restrictions:

- E46/R50 Only one solar sensor is fitted. Stratification is not affected.

- E38/E39 Two sensors are fitted in the solar sensor housing, aligned to the left and right.
