The Ideal Boilers part pack contains 2x control thermistors and clips and is designed for use in Logic and Logic+ boilers. The thermistor decreases circuit resistance in line with temperature increases. A boiler's printed control board sends a current to the thermistor, deciding whether a decrease or increase in heat is required by reading the relative resistance.
Comes with clip attached
