A Printed Circuit Board or PCB controls every action and can be found in most appliances from boilers to warm air units and fires. This is the 'brain' of the boiler. They are often referred to as a PCB, control box, mother board, driver board, sequence board, ignition board or power board. Conductive pathways are etched or "printed" onto board, connecting different components on the PCB, such as transistors, resistors, and integrated circuits. Manufacturers Include Grant and Worcester
We recommend that a Printed Circuit Board (PCB) is fitted by a fully qualified gas safe certified plumber.
