Golf Mk4
| Function of operating and display unit for Climatronic control unit -E87- with Climatronic control unit -J255- |
| 1 - | Windscreen defroster button |
| 2 - | Display for blower speed |
| q | In automatic operation → Item a medium blower speed is displayed regardless of the actual blower speed. |
| 3 - | Display for ambient temperature |
| q | If the road speed falls below 15 km/h and the coolant temperature is above 70° C, the value displayed will not change. The actual ambient temperature measured is not displayed because it is influenced by the heat build-up in the engine at lower speeds. |
| 4 - | Display for defrosting windscreen |
| 5 - | Display for air recirculation |
| 6 - | Display for air flow direction |
| q | Pressing button → Item switches the footwell air-flow display on or off. |
| q | Pressing button → Item switches the upper-body air-flow display on or off. |
| 7 - | Display for selected interior temperature |
| q | Switching between Celsius and Fahrenheit: |
| q | Press and hold button → Item and then press button → Item. |
| q | The corresponding temperature unit appears in the display. |
| 8 - | Operating mode display |
| “AUTO”: Automatic mode |
| q | In automatic mode, the Climatronic maintains the selected interior temperature automatically. With this setting, the vent air temperature, the blower speed and the air distribution are controlled automatically. |
| “ECON”: conditioning system off |
| q | In ECON mode, only the air conditioner compressor is switched off; heating and ventilation continue to be controlled automatically. |
Note| For vehicles that are not equipped with a magnetic coupling on the air conditioner compressor, the swash plate in the air conditioner compressor is set to a delivery rate of almost zero; heating and ventilation continue to be controlled automatically. |
| “OFF”: complete system is switched off. |
| q | To switch off, press → Item. |
| q | Because the flaps remain in the last position set, this manner of selection should only be used in special circumstances e.g. when there is a malfunction. |
| 9 - | Button for automatic mode |
| 10 - | Dash panel temperature sensor -G56- and temperature sensor blower -V42- |
| q | Fitting location for right-hand drive vehicles. |
| q | The Climatronic control unit -J255-, the operating and display unit for Climatronic air conditioning system -E87- and the dash panel temperature sensor -G56- with temperature sensor blower -V42- are combined in one unit which cannot be dismantled. |
| q | Checking: vehicle diagnosis, testing and information system -VAS 5051B- in guided fault finding. |
| q | Task: the temperature sensor controls the temperature flap and the fresh air blower based on the temperature. |
| q | In event of failure of dash panel temperature sensor -G56-: continued operation assuming value of +24° C. |
| 11 - | “ECON” button |
| q | In ECON mode, only the air conditioner compressor is switched off; heating and ventilation continue to be controlled automatically. |
Note| For vehicles that are not equipped with an air conditioning system magnetic coupling -N25- on the air conditioner compressor, the swash plate in the air conditioner compressor is set to a delivery rate of almost zero; heating and ventilation continue to be controlled automatically. |
