Product Information:
The printed circuit board or (PCB) is the boiler’s central control. It monitors and controls every process that occurs via the sensors, thermostats, and switches. It also enforces the safety protocols, 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.
