Honeywell V4073A1039 22mm 3 Port Mid Position Valve
The Honeywell V4073A 22mm Mid-position Diverter Valve has been designed to control the flow of water in domestic central heating systems, where both radiator and hot water cylinder circuits are pumped. It is typically suited for small to medium sized installations.

The Honeywell V4073A 22mm Mid-position Diverter Valve should be used in conjunction with a room thermostat and cylinder thermostat to provide full temperature control of a conventional, fully pumped central heating installation. When used in this way, the control system is known as Sundial Y Plan and the components can be connected together using the Sundial Plan Wiring Centre which has dedicated terminations and there is no need for a wiring diagram.
