Integrated automatic heating/air conditioning system (IHKA): Notes
The integrated automatic heating and air conditioning system (IHKA) with left-right separation is a water-regulated heating and air conditioning system.
The following equipment specifications are available:
- Integrated automatic heating and air conditioning system in basis version (IHKA Basis)
The IHKA Basis is an Automatic air conditioning with 2.5 zone control. That means: Left-right separation for driver's and front passenger side and control in the rear (without left-right separation)
- Integrated automatic heating and air-conditioning system in High version (IHKA High) with rear automatic rear air-conditioning system (FKA)
The IHKA High with FKA is an automatic air conditioning with 4-zone control. In addition to the left-right separation for the driver and front passenger sides, the FKA also enables a left-right separation in the rear passenger compartment.
- Integrated automatic heating and air-conditioning system in High version (IHKA High) with rear automatic rear air-conditioning system (FKA) and automatic rear air conditioning (HKA)
The IHKA High with FKA and HKA is an automatic air conditioning with 4-zone control. The HKA with left-right separation means that the air supply and air temperature (only cooling possible) in the rear passenger compartment is additionally regulated via the roof air vent.
The major new features of the integrated automatic heating and air conditioning system (IHKA) are:
- Control panel for IHKA is a unit with the control panel for audio
- Fresh air and recirculated air fan of the heating and air conditioning system positioned in the engine compartment
- Ioniser to prevent bacteria growth in the IHKA
