Baxi Printed Circuit Board (Pcb) (Page 9)
The printed circuit board or ( pcb ) is the control centre of the appliance. It monitors and controls every process that occurs via the thermostats, sensors and switches. 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.
