Potterton Thermistors (Page 2)
The thermistor works by decreasing current resistance in a manner that is inversely proportional to the temperature of the thermistor. The electronic control board sends a current to the thermistor and can tell whether an increase or decrease in heat is needed by the resistance provided by the thermistor.
