摘要:
The rotary control unit to which the invention relates, in particular nominal value rotary control unit for a vehicle heating system and in particular vehicle air conditioning system, is provided with a rotatable rotary control element (14), an electric motor (16) with a driveshaft (17) which is mechanically coupled to the rotary control element (14), an activation circuit (24) for supplying the electric motor (16) with power for the purpose of generating a holding moment in order to prevent undesired rotation of the rotary control element (14) and/or to build up a resistance as the rotary control element is rotated, and a sensor unit (22) for detecting a hand which is approaching the rotary control element (14) or is touching the rotary control element (14). The activation circuit (24) for supplying power to the electric motor (16) can be activated if the sensor unit (22) detects a hand which is approaching the rotary control element (14) or is touching the rotary control element (14).
