26 Sensor curves
z Isolate the heating system from the power supply
before taking any readings.
Fault test (without room temperature sensor)
z Remove the sensor terminals.
z Check the resistance at the sensor cable ends using
an ohmmeter.
z Check the sensor temperature with a thermometer.
Using the diagram you can check whether temperature
and resistance correlate.
USER INFORMATION
The sensor tolerance for all curves is up
to
3 %/25 °C
