For use with Main HE, Combi, Performa, and System IE boilers, this genuine Baxi thermistor sensor is for you. As temperature rises, the thermistor reduces circuit resistance. The printed control board (PCB) of a boiler provides a current to the thermistor, reading the relative resistance to determine if a reduction or increase in heat is necessary. This part also comes with the washer included.
