The Vaillant negative temperature coefficient thermistor sensor works by decreasing current resistance in a manner that is inversely proportional to the temperature of the thermistor. The electronic control sends a current to the thermistor and can tell whether an increase or decrease in heat is needed.

A Vaillant temperature or NTC sensor for ecoTEC VU (condensing), VKK ecoCRAFT (condensing) and Pump 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.  We carry over 300 of the most in demand parts in-branch and stock over 25,000 spare parts available for next-day timed delivery.
