A Vaillant NTC sensor for ecoTEC VUW (condensing) and Guernsey/Jersey only (condensing) boilers. The sensor or thermistor decreases 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.
