Orders received before 4pm are usually dispatched for next business day delivery. This Ideal Boilers control thermistor is designed for use in Esprit, Isar, Esprit 2, and Evo boilers. The thermistor decreases circuit resistance in line with temperature increases. A boiler control board sends a current to the thermistor, deciding whether a decrease or increase in heat is required by reading the relative resistance. This is a genuine part.
