Ferroli 39810230 Sensor - Domestic Hot Water

A Ferroli sensor for domestic hot water controlled by Modena HE, Euroterm, Extrema, T-One, Combi, DOMIcompact, DOMIcondens, iBoiler, Optimax HE Plus, Tech and FERCondens boilers. The sensor is employed to decrease circuit resistance in line with temperature increases. A boiler's printed control board (PCB) sends a current to the thermistor, deciding whether a decrease or increase in heat is required by reading the relative resistance.
