The flow switch acts as a safety instrument.
It is a switch with an in-built sensor that sits in the pipework for both the central heating and DHW systems.
When the pump is powered up, the flow switches senses this movement and feeds the information back to the electronic control, allowing the ignition sequence to progress.
The flow switches function is to make sure that the burner cannot switch on if the system is low on water or dry.
