SOURCE: I have a Schaerer Siena it is showing an error NTC
This indicates a fault with the temperature sensor on one of the boilers. Generally it should display NTC Steam or NTC hot water so this will indicate which boiler is faulty. 95% of the time, the complete boiler needs to be replaced as the temp sensor is built into it and cannot be replaced alone. Adds to the expense unfortunately.
