forms. To prevent the windows from misting over, the IHKA control unit starts to work through a table of
measures as soon as a certain level of humidity is detected at the windscreen.
-
LIN bus (Local Interconnect Network bus)
The LIN bus serves to actuate flap motors, the electric auxiliary heater and the blower motor in the heating/air-
conditioning system.
-
Convertible program (E64 only)
When the convertible top is opened and the air-conditioning system is in automatic mode, the convertible
program is automatically activated.
The convertible program adapts the air-conditioner settings (blower, airflow, temperature) to the conditions
created by the open top. The settings do not have to be changed when the top is opened or closed.
The convertible program is stored in the IHKA control unit.

Differences/modifications from E39:
-
New IHKA controls with additional functions: OFF button, temperature and airflow are set with rotary switches.
On the IHKA Basic, the manual air distribution is set with the IHKA controls. On the IHKA High, the manual air
distribution is set with the controller on the CID (Central Information Display) .
-
Revised display concept
The scale on the rotary switch for the blower setting has a 9-element LED display. The manually blower speed
setting is shown by the corresponding LEDs lighting up. In automatic mode, the display remains off (IHKA High
only).
The LCD display from earlier versions has been discontinued. Additional air-conditioning functions such as air
stratification or independent heater (option 536) are selected and activated in the Central Information Display
(CID) using the controller.
-
The flap drives are only operated by flap motors.
-
Separate left/right-hand footwell flaps, (IHKA High only)
-
Separate ventilation flaps, (IHKA High only)
-
Intake fan arrangement in the heating/air-conditioning system.
The fan is located after the evaporator.
-
On vehicles with diesel engine, a heating system heat exchanger is installed with integrated electric auxiliary
heater. The same heating system heat exchanger is used for both Basic and High versions.
-
Clutchless, externally actuated a/c compressor with regulated performance
-
Sensor for automatic air-recirculation control (AUC sensor, IHKA High only)
-
Solar sensor for taking external light/heat sources into account, which could affect the air conditioning in the
vehicle interior (IHKA High only).
