Discharge temperature sensor providing incorrect reading: how to verify it

An incorrect discharge temperature reading can cause false alarms or power limitation.

Initial check

Compare the controller reading with an independent measurement at the same point.

Electrical check

Check the sensor resistance, wiring, plug, and potential poor contact.

Sensor position

If it is not properly in contact with the pipe, it may measure a lower or unstable temperature.

Correct action

Do not change protection limits to hide an incorrect reading.
