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 page107).
Check the installation and replace
sensor, if necessary, in case of
severe deviation.
