Abstract

The invention relates to a climate control system for the interior of a motor vehicle, having a blower regulator, heating control unit or brushless blower motor, as well as function components such as operating elements, sensors, clocking valves and adjusting drive mechanisms, which are connected to one another and to the vehicle battery via connecting lines and to which the information required to operate the blower regulator, heating control unit or brushless blower motor are transmitted. The cabling and the control/regulation are minimized and simplified by providing that the blower regulator, the heating control unit, or the brushless blower motor is combined with the function components to make a pre-wired climate control unit, to which the supply voltage of the vehicle battery; that the blower regulator, the heating control unit, or the brushless blower motor is designed in bus-capable fashion with a microcomputer, which communicates via a bus interface with a climate control operating device supplied by the supply voltage; and that the information required for operating the climate control apparatus can be transmitted between the climate control operating device and microcom…
