Sensor failure
If a sensor fails, the LED display will show information about the failure of that sensor. The
boiler water sensor and the flue gas temperature sensor are crucial for the safe operation
of the boiler, therefore the boiler only fails or stops when these two are malfunctioning. In
the event of a failure of the supply water sensor, operation can be uninterrupted as the
temperature in the storage tank is maintained by the controller by switching off the boiler
and return water differential pumps, only in the event of a failure of the return water sensor
the motor drive of the 3P mixing valve will need to be set to manual override and opened to
a good half.
NO TCI, is displayed when the flue gas sensor is
malfunctioning. The boiler will stop automatically.
NO NTC, is displayed if there is a fault in the boiler
water temperature sensor. As in the previous
example, the boiler will automatically shut down
