Cabin Temperature Sensor / Switch: Description and Operation

In-Car Temperature Sensor

Purpose
The in-car temperature sensor with fresh air blower serves for measuring the temperature in the vehicle passenger compartment

Function
The in-car temperature sensor is equipped with an aspirator blower which continuously sucks air out of the vehicle passenger compartment for measurement of the temperature.
It is connected to the push-button control module by a separate electric lead.

The aspirator blower provides continuous circulation of the interior air around the in-car temperature sensor to ensure a high degree of control accuracy.
