| This high pressure sender -G65- is installed instead of the air-conditioner pressure switch -F129-. |
| The high pressure sender generates a rectangular signal or a datagram when voltage is applied. This signal changes according to the pressure in the installation. |
| With this signal, the connected control units (refrigerant fan control unit, engine control unit air-conditioner control unit and display, Climatronic -E87-, or else the Climatronic control unit -J255-, etc.) calculate the pressure of the refrigerant circuit, and, according to this pressure, activate the refrigerant and engine fans, the air-conditioner electromagnetic coupling -N25-, or adjust the activation of the air-conditioner compressor regulating valve -N280-. |
