The Remeha domestic hot water flow switch, which has a built-in sensor and is employed as a safety device, is installed in the piping for both the central heating and hot water systems. The printed circuit board receives the information from the flow switch, which is built to detect movement in the pipework, and uses it to advance the ignition sequence. The flow switch's function is to ensure that there is enough water in the system and to stop the burner from turning on if there is not enough water.
