Abstract
Abstract An interior climate control system in which a vehicle fan of the vehicle's own ventilation device, an openable and closable vehicle opening, such as a roof opening or a window opening, and a heater that can be operated independently of the engine are linked by an operating control circuit into a functional unit so that, when a predetermined, upper temperature limit is exceeded, a control circuit allocated to the operating devices for the openable and closable vehicle opening is controlled and activated, and so that, when the temperature falls below a predetermined, lower limit, the engine-independent heater is controlled and started. A pre-air conditioning operation or a preheating operation in the interior climate control system can be achieved by a remote control device and/or by a preadjustable timer device by the operating control circuit.
