A simple and space-saving, nevertheless effective and low-noise apparatus for the interior compartment air of a motor vehicle, to impact a temperature sensor of an automatic heating or air-conditioning system is provided. This invention achieves these results by providing, in place of a separate auxiliary fan, an auxiliary air current drawn from the interior compartment and sensing the temperature of that current with a sensor. The impeller of the fan used for circulation in the interior compartment is also equipped with supplemental blades outside its actual main air current to generate an auxiliary air current which is drawn through a separate air channel from the interior compartment passing over the sensor. This air channel, such as a flexible hose, is suitably mounted between the air discharge opening on the dashboard and an air-feed opening in the spiral housing backwall of the fan. This apparatus is particularly suitable for application in the actual value detection of the interior compartment air temperature in a motor vehicle with an automatic heating or air-conditioning system.
