This V4073A motorised diverter valve with 28mm compression connections controls the flow of water in domestic central heating systems, where both radiator and hot water cylinder circuits are pumped. Suitable for small-to-medium sized installations, this mid-position diverter valve should be used in conjunction with a room thermostat and cylinder thermostat for full temperature control of a conventional, fully pumped central heating installation. This type of control system is known as Sundial Y Plan and components can be connected using the Sundial Plan Wiring Centre, including dedicated terminations with no need for a wiring diagram.
