The Potterton printed circuit board box is designed for use in Potterton's Kingfisher Mf and Kingfisher boilers. The control centre of a boiler, the printed circuit board monitors and controls every process occurring throughout a system via switches, thermostats and sensors. It enforces safety measures too, shutting down boiler functions if internal readings indicate any type of fault such as high pressure or low water levels.
