  • Temperature control unit for a motor vehicle
    Patent number: 5070931
    Abstract: A temperature control unit has an air distribution setting device, an air volume setting device and a regulating control unit which determined optimum settings for the air distribution setting device and for the air volume setting device. The unit also includes a desired temperature setting device supplying a nominal inside temperature to the regulating control unit. Sensors provide an input indicative of the actual inside temperature to the regulating control unit. Output indicators, preferably in the form of light emitting diodes disposed along selecting paths of the setting devices indicate to the operator the calculated optimum settings for the appropriate setting device to be selected to allow for a controlled, external adjustment of the air distribution setting device and of the air volume setting device.
