IHKA Controls

On the IHKA system all functions have automatic and some manual modes of operation. The automatic modes provide optimum control of the system and require no manual intervention. The manual modes allow individual functions of automatic operation to be overridden, to accommodate personal preferences.

The IHKA control system controls the operation of the refrigerant system and the control flaps in the heater assembly to control the temperature and distribution of air in the vehicle interior. It also outputs signals to the BC1 to control the fresh/recirculation air servomotor and to the blower to control the air volume.
