The printed circuit board (PCB) is the control centre of the appliance.
It constantly checks every process that occurs via the switches, thermostats and sensors.
It also enforces the safety parameters, 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 essentially the brains of the appliance, ensuring everything is running correctly and safely.
