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