Title: Operating device for a ventilation system in a vehicle

Abstract: The invention relates to a control unit for a ventilation arrangement in a vehicle. The control unit is designed to indicate and initiate supply of an air flow to at least three intake air regions in the vehicle, which regions may include a defroster region, a panel region and a floor region. The control unit incorporates a first control device (1) designed to indicate and initiate a supply of air flow to the three intake air regions by a first intake air distribution which in each control position caters for at most two of the intake air regions. The control unit also incorporates a second control device (2) designed to indicate and initiate supply of the air flow to the three intake air regions by a second intake air distribution which in each control position caters for at most two of the intake air regions. The result is that the intake air can be distributed variably between the three intake air regions.
