Operating system for a motor vehicle automatic air-conditioning system
First Claim
1. A control unit for an automatic air-conditioning system for motor vehicles, with adjusting means and indicators at least for air distribution, air volume and air temperature, the automatic air-conditioning system having an automatic mode and a manual mode, the control unit comprising:
- a nominal-value adjusting means for at least one of air distribution, air volume and air temperature, where provision is made for a manually adjustable, analog nominal-value adjusting means;
an indicator device for at least one of air distribution, air volume and air temperature, where an analog indicator device is associated with each analog nominal-value adjusting means; and
an independent separate analog drive for, in a manual adjustment mode, directly slaving the indicator device in accordance with a preset nominal value as the nominal-value indicator device and for, in an automatic adjustment mode, directly slaving the indicator device in accordance with the given value of at least one of air distribution, air volume and air temperature, as actual-value indicator device.

Abstract
The invention concerns a control unit for an automatic air-conditioning system for motor vehicles, with adjusting and/or indicating means at least for "air distribution", "air volume" and "air temperature" with the following features:
(a) As nominal-value adjusting means for "air distribution" and/or "air volume" and/or "air temperature", provision is made in each case for an operator-regulated analog nominal-value adjusting device (2, 3 and 4, respectively);
(b) as nominal-value indicating means for "air distribution" and/or "air volume", an analog nominal-value indicating device (2.1; 2.2 or 2.1; 2.3 or 2.1; 2.4 or 3.1; 3.2) is associated with each nominal-value adjusting device (2 or 3), such indicating device being directly slaved by an independent separate drive;
(c) the nominal-value indicating device in the manual adjustment mode is, in the automatic mode, concomitantly used in each case as an actual-value indicating device for "air distribution" and/or "air volume", such actual-value indicating device being directly slaved by the separate drive in accordance with the given actual value.

13. A control unit for an air-conditioning system operable in an automatic mode and a manual mode, the control unit comprising:
-
at least one nominal-value adjusting device for adjusting at least one of air distribution, air volume and air temperature of the air-conditioning system; at least an indicator associated with each adjusting device; and analog drive for directly driving the indicator to indicate a pre-set nominal value in the manual mode and to indicate an actual value of at least one of air distribution, air volume and air temperature in the automatic mode. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A control unit for an air-conditioning system operable in an automatic mode and a manual mode, the control unit comprising:
-
nominal-value adjusting means for adjusting at least one of air distribution, air volume and air-temperature of the air conditioning system; means, associated with each said adjusting means, for indicating at least one of air distribution, air volume and air temperature; and means for directly driving the indicator to indicate a pre-set nominal value in the manual mode and to indicate an actual value of at least one of air distribution, air volume and air temperature in the automatic mode.
