The PCB or printed circuit board is the boilers central control.

It controls and monitors every process that occurs via the switches, thermostats and sensors.

It also enforces the safety measures, making sure that the boiler ceases to function if any of the internal readings point to any fault in the boilers processes.

The printed circuit board is effectively the brain of your boiler, It is programmed to ensure everything is running as it should.
