Worcester Bosch 87229638580 temperature limit sensor

Product Description

This Worcester Bosch sensor, or thermistor, is compatible with CDi Series, Greenstar, RD Series and Greenstar ErP boilers. The sensor is employed to decrease 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.
