The Andrews Water Heaters sensor is designed for use in CWH and LCWH appliances. The thermistor reduces circuit resistance as the temperature rises. The printed control board of a boiler sends a current to the thermistor, which reads the relative resistance to determine whether a decrease or increase in heat is required.
Comes with clip attached
