Worcester Printed Circuit Board (Pcb) (Page 5)
The printed circuit board or ( pcb ) is the boilers central control. 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 any fault in the boilers operation. The printed circuit board is essentially the brains of the appliance, ensuring everything is running correctly and safely.
