Functional description of used sensors
Control temperature sensor
The control sensor must always be connected and is used for controlling the cut-in and cut-out of
the compressor according to the set-point. The sensor is also used for the displayed temperature.
Most common placement is in the return air to the evaporator.
Evaporator sensor
The evaporator sensor is only used for de-icing of the evaporator and has no control purpose.
Place the sensor where the ice melts last.
Please be aware of that sharp fins can damage the cable.
Condenser temperature sensor
The condenser sensor is used to protect the compressor against high pressure when the
condenser is blocked or the condenser fan fails.
Place the sensor at the liquid side of the condenser. Use a metal bracket or metal tape to ensure
good thermal conductivity. Be sure that the cable does not pass hot spots at the compressor or
condenser that exceeds 80 °C.
