Johnson & Starley Printed Circuit Board (Pcb)
The printed circuit board or ( pcb ) is the boilers central control. It controls and monitors 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 an error in the boilers operation. The printed circuit board is essentially the brains of the appliance, ensuring everything is running correctly and safely.
