Boiler water temperature sensor and cylinder temperature sensor
Connection
See page 66.
Checking sensor
1. Pull plug § or %.
2. Check the sensor resistance at
terminals "1" and "2" or "2" and
"3" (if a second cylinder
temperature sensor has been
connected) of the plug.
3. Compare the test result with the
actual temperature (for scanning,
see page107).
Check the installation and replace
sensor, if necessary, in case of
severe deviation.
