Abstract

In the case of a control unit for a vehicle heating or air-conditioning unit having a vehicle-borne monitor permitting access to different display and control menus, in addition to a selection possibility for an automatic program by way of an automatic key, an individual adjusting possibility is provided for the temperature distribution and/or air distribution in different zones of the vehicle interior which can be displayed and selected on the vehicle-borne monitor. The different zones of the vehicle interior can be selected by way of a control element by means of a symbolic representation on the vehicle-borne monitor. An air quantity selector is provided which is arranged in a hidden manner with respect to a temperature selector constructed as a rotary-type knob. For this purpose, a rotary-type knob for the air quantity is provided concentrically with respect to the rotary-type knob for the temperature adjustment and is normally recessed with respect to this rotary-type knob and can be brought into a protruding position with respect to it.
