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