The Glow-worm printed circuit board is the control centre of the appliance. It constantly checks every process that occurs via the switches, thermostats and sensors. It also enforces the safety measures, making sure that the boiler ceases to function if any of the internal readings point to any fault in the boiler's operation. The printed circuit board is effectively the brain of the boiler. It is programmed to ensure everything is running as it should be.
