The printed circuit board (PCB) is the boilers central control.

It monitors and controls every process that occurs via the thermostats, sensors and switches.

It also enforces the safety protocols, 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 essentially the brains of the appliance, ensuring everything is running correctly and safely.
