Potterton Printed Circuit Board (Pcb) (Page 3)
The printed circuit board or ( pcb ) is the control centre of the appliance. It constantly checks 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 effectively the brain of your boiler, It is programmed to ensure everything is running as it should.
