What it is
The Glow-worm 0020047027 is an NTC sensor used across the Easicom, Energy, Energy7, Essential and Betacom boiler families. It is a thermistor-type temperature sensor that feeds temperature information back to the boiler control board, and is also listed as a temperature limiter. It forms part of the boiler's temperature monitoring and safety circuit.
