BAXI 720878202 PCB – Combi/System

Product Description:

The printed circuit board (PCB) is the boiler’s central control. It monitors and controls every process that occurs via the thermostats, switches, and sensors. It also enforces safety measures, making sure that the boiler ceases to function if any of the internal readings point to an error in the operation of the boiler. The printed circuit board is essentially the brains of the appliance, ensuring everything is running correctly and safely.
