Abstract
A circuit arrangement for actuating an air-conditioning system or an automatic air conditioner in a vehicle, in which it is possible to switch the air-conditioning system or automatic air conditioner on and off when the engine is operating. Here, the air-conditioning system or automatic air conditioner is switched off, if the air-conditioning system or automatic air conditioner is operating while the engine is operating and the engine is switched off. Further, the air-conditioning system or automatic air conditioner continues to possess a function with which, when the engine of the vehicle is stationary, the residual heat of the engine is utilizable. Additionally, at least one function of the air-conditioning system or automatic air conditioner, which is switchable manually when the engine is operating, is switchable via the same control element used to activate and deactivate the function in which the residual heat is utilized when the engine is stationary.
