The printed circuit board or (PCB) is the control centre of the appliance. It oversees every process that occurs via the switches, thermostats and sensors. It also enforces the safety parameters, making sure that the boiler ceases to function if any of the internal readings point to an error in the boilers operation. The printed circuit board is effectively the brain of your boiler, It is programmed to ensure everything is running as it should.
