Electrical Components Which Are Not Fitted On The Refrigerant Circuit - Skoda Citigo 2012 Workshop Manual

2.4.4 Regulating valve for compressor of air
conditioning system - N280-
The regulating valve is installed in the AC compressor. It is actu‐
ated by the control and display unit for air conditioner Climatronic
- E87- or the Climatronic control unit - J255- (if necessary specif‐
ically designed for vehicles via a databus and an additional control
unit). The pressure on the low-pressure side is influenced by the
regulating valve and thus the temperature in the evaporator is
regulated.
Note
The regulating valve for compressor of air conditioning system -
N280- is a component of the AC compressor and cannot be
replaced separately.

ted on the refrigerant circuit

temperature sensor G308 ", page 29
2.5.1 Radiator fan control unit - J293-
This control unit switches the magnetic coupling and thus the AC
compressor on and off. It turns on the coolant fans and calculates
the pressure in the refrigerant circuit on vehicles with high-pres‐
sure sender - G65- ⇒ Current flow diagrams, Electrical fault
finding and Fitting locations.
2.5.2 Evaporator vent temperature sender -
G263- or evaporator temperature sen‐
sor - G308-
The evaporator vent temperature sender - G263- determines the
temperature behind the evaporator. This value passes on to the
air conditioning system control unit and serves as a reference
signal for the regulation of the AC compressor. Thus, icing of the
evaporator is avoided.
