Heatrae Printed Circuit Board (Pcb) (Page 3)

The printed circuit board or ( pcb ) is the control centre of the appliance. It monitors and controls every process that occurs via the switches, thermostats and sensors. It also enforces the safety protocols, making sure that the boiler ceases to function if any of the internal readings point to any kind of error or fault. The printed circuit board is essentially the brains of the appliance, ensuring everything is running correctly and safely.
