Alpha Cb CBX SY Printed Circuit Board 1.025576
This Printed Circuit Board or Pcb as it is commonly known is located behind the user control section of a gas boiler. It runs the entire boiler ensuring it monitors temperatures within the boiler, air flow pressures and also controls the gas supply to the burners. This is achieved by receiving information from safety devices within the boiler such as thermistors, temperature sensors, air pressure switches and gas valves. If any of the safety devices detect excessive readings or fail the information is sent back to the printed circuit board which in turn switches off the boiler to ensure safety to life and property. Below is a list of boilers this printed circuit board fits.
