A Glow-worm printed circuit board for boiler models such as the Ultimate, Micron, Protherm, Ikon and Xeon. The printed circuit board, which serves as a boiler's command centre, uses switches, thermostats and sensors to monitor and regulate every operation taking place within a system. It also enforces safety precautions, turning off boiler functions if internal readings point to any issue, such as excessive pressure or low water levels.
