This refrigerant pressure and temperature sender - G395- is fitted
in place of the high-pressure sender - G65- or air conditioning
system pressure switch - F129- .
The pressure signal is monitored continuously, whereas the tem‐
perature signal is monitored only at temperatures greater than 0°
C.
The Climatronic control unit - J255- works with this information
and controls the coolant radiator fans accordingly and actuates
the air conditioning system compressor regulating valve - N280- .
2.4.8 Air conditioner compressor regulating
valve - N280-
The regulating valve is fitted to the air conditioner compressor. It
is activated by the operating and display unit for Climatronic air
conditioning system - E87- or the Climatronic control unit - J255-
The regulating valve influences the pressure in the low-pressure
side and thus the temperature at the evaporator.
Note
The air conditioner compressor regulating valve - N280- is an in‐
tegral part of the air conditioner compressor and cannot be re‐
newed individually.
2.5 Electrical components not installed in
refrigerant circuit
2.5.1 Control and regulating unit for air condi‐
tioning system - J127-
This control and regulating unit switches off the refrigerant flow
through the second evaporator if the temperature at the cooling
fins of the second evaporator falls to the freezing point of water
(icing protection).
2.5.2 Radiator fan control unit - J293-
Note
Available in various designs, sometimes separately.
