This Johnson and Starley flue temperature sensor is compatible with RENO Heat, RENO Xtra, RENO Combi and RENO System boilers. The sensor is employed to increase circuit resistance in line with temperature drops. 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.
