IHKA control unit with integrated control panel: IHKA-High
The IHKA High has separate temperature settings for the driver's side and the front passenger side.
The IHKA-High has no display for showing the selected temperature setting and the blower speed.
The IHKA-High 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's 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 adjusting values for blow-out temperature and blower output. The seat heating (if fitted) is also operated using buttons in the operating unit.
