The household hot water and central heating systems’ piping contains a sensor that is incorporated into the flow switch. The flow switch detects the pump’s activation and relays that information to the system’s PCB, starting the ignition sequence. The flow switch will make sure that operation is stopped if it detects that the system is dry or low on water.
