Solar sensor
| Solar sensor |
The solar sensor is placed on the top of the dashboard. It measures mainly infra-red radiation (heat radiation). In the event of an increase in solar radiation and an outside temperature exceeding + 15 ° C the ACC control module increases the ventilation fan speed since more cold air must be supplied. The fan speed is immediately changed in the event of a change in the solar radiation. The fact that the solar sensor measures mainly heat radiation means that it cannot be tested with fluorescent light, only sunlight or light from a bulb must be used. If the solar sensor value is missing the substitute value 0 volt = night is set.
