The thermistor decreases current resistance as the temperature of the thermistor rises. The printed circuit board sends a current to the thermistor and can tell whether an increase or decrease in temperature is needed by the relative resistance in the the

Glow-Worm Thermistor Control
Fits Boilers: Glow-Worm Micron 60/70/80FF

A genuine Glow-worm part, this thermistor is designed for use in Micron boilers and is supplied with a lead.  The 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.  As the leading supplier of parts for all the major boiler manufacturers we’ve got a wealth of experience and knowledge in this area, and with over 450 branches we carry more heating spare parts in more places than any other merchant to help you improve your first time fix rate.
