  8. Parking Heater Radio Receiver -R64-
    • Depending on the vehicle equipment level
    • For vehicles with a parking heater
    • As soon as an activation signal is detected by the hand-held transmitter of the auxiliary heater radio receiver/remote control, the Auxiliary Heater Control Module -J364- queries the Climatronic Control Module -J255- control head. The Climatronic Control Module -J255- then decides whether parking heater operation is necessary to reach the set temperatures or parking ventilation operation is sufficient.
      NOTE:

      Note the correct allocation of the A/C control head, the Climatronic Control Module -J255- to the hand-held transmitter and to the Parking Heater Radio Receiver -R64-. There are different versions of the hand-held transmitter and the Parking Heater Radio Receiver -R64- on a Climatronic Control Module -J255- with a part number through index "AH" (for example, recognizable on the button AC  ) and with a part number from index "AJ" (for example, recognizable on the button A/C  ).
