| t
| Depending on the setting at the operating and display unit, Climatronic control unit -J255-, the temperature at the evaporator is regulated to the following values: |
| –
| In normal control mode between 2 °C and 10 °C |
| –
| At temperatures less than 13 °C at least 3 °C below the ambient temperature determined but not less than 2 °C |
| –
| At temperatures less than 16 °C and with rainfall (windscreen wipers switched on) at least 6 °C below the ambient temperature determined but not less than 2 °C. |
| –
| 2 °C with “Lo” temperature setting at operating and display unit, Climatronic control unit -J255- |
Note | t
| If a temperature below 2 °C is measured for a lengthy period by the evaporator outflow temperature sender -G263-, the operating and display unit, Climatronic control unit -J255- switches off the compressor. |
| t
| The value measured by the evaporator outflow temperature sender -G263- is used to control the evaporator temperature. The evaporator temperature is altered by actuating the air conditioning system compressor regulating valve -N280- (display group “001”) → Chapter. |
| t
| - At least 5 °C, however not less than 2 °C with “recirculated-air mode” set at operating and display unit, Climatronic control unit -J255-. |
| t
| At higher ambient temperatures, the specified temperatures are not always attained at the evaporator outflow temperature sender -G263- (despite the compressor operating at maximum output). |
| t
| Actuation of the air conditioning system compressor regulating valve -N280- to control the compressor output is displayed in zones “1” and “2” of display group “001” → Chapter. |
| t
| If the evaporator outflow temperature sender -G263- has not been properly installed or if it supplies an excessively high temperature value, the evaporator may ice up (the operating and display unit, Climatronic control unit -J255- assumes from the measured value that the required evaporator temperature has not been attained). |
