IHKA control unit with integrated control panel
The control panel and control unit together form a single component. The control panel of the IHKA forms a unit with the audio control panel.
The IHKA is operated using the operating elements shown in the illustration. The nominal temperature is set on the control panel separately for the driver's and front passenger side. The control unit regulates the climate control to the desired temperature. In doing so, the control unit picks up the sensor signals and continuously adapts the control variables for blow-out temperature and blower output. The seat heating and active seat ventilation (if fitted) are also operated using buttons in the control panel.
