Heatline Dhw Ntc Sensor

This Heatline NTC sensor is compatible with Hydroline, S Series, Vizo, Capriz, Solaris, Sargon and C Series 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.
