The Potterton printed circuit board is the control centre of the appliance. 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 any fault in the boiler's processes. The printed circuit board is essentially the brains of the appliance, ensuring everything is running correctly and safely.
