Operation Manual
Solution
Check for sensor integrity.
Check correct sensors operation
according information about kOhm
(k ) range related to temperature
values.
Check if sensor is shorted with a
resistance measurement.
Check for correct installation of the
sensor on refrigerant circuit pipe.
Check for absence of water or
humidity on sensor electrical
contacts.
Check for correct plug-in of the
electrical connectors.
Check for correct sensors wiring also
according with electrical scheme.
