The flow switch acts as a safety device.

It is a switch with an in-built sensor that sits in the pipework for both the heating and domestic hot water systems.

When the pump is switched on, the flow switches senses this movement.

This feeds the information back to the electronic control, allowing the ignition sequence to progress.

The flow switches purpose is to make sure that the burner cannot switch on if the system is dry or low on water.
