SIEMENS STP73 AC 24V 2-POSITION/PDM ELECTROTHERMAL ACTIVATOR.

The diverter valve is a mechanism that is only found on a combi boiler, which is used to allow hot water to be guided to the taps in a hot water system or to the radiators in a central heating system. This is a feature that separates combi boilers from normal boilers due to the diverter valve allowing hot water to both central heating and taps without a cylinder .
