| High-pressure sender -G65- |
Note | The high pressure sender -G65- (specifically designed for vehicles) can be installed instead of the pressure switch for the air conditioning system -F129-. |
| The high-pressure sender -G65- determines the pressure in the refrigerant circuit and transmits the values to the Air conditioning system control unit -J301- or to the Climatronic control unit -J255-. |
| The following are shifted via these control units: |
| t
| The radiator fan -V7- switches to the next speed in the event of a pressure rise in the refrigerant circuit |
| t
| Reduction of the compressor output if the pressure is too high, 3.2 MPa (32 bar), e.g. too little engine cooling |
| t
| Reduction of the compressor output if the pressure is too low, 0.2 MPa (2 bar), e.g. refrigerant loss |
