Description
The thermistor decreases the current resistance as the temperature increases. The PCB sends a current to the thermistor and can tell whether an increase or decrease in temperature is needed by the resistance provided by the thermistor.
We recommend that all parts are fitted by a fully qualified gas safe certified technician.
