A boiler’s PCB (Printed Circuit Board) is its central brain, controlling and coordinating all operations, from ignition to safety shutdowns, by monitoring sensors, managing heat/hot water demands, and ensuring components like the fan, gas valve, and pump work together safely and efficiently.

It receives signals from thermostats and switches, then instructs other parts, locking out the boiler and showing fault codes if it detects a problem, like an airflow issue
