Motorised Zone Valve

The V4073A 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.

An alternative method of wiring is to use the Honeywell 10-way Junction Box (42002116-002) together with the Honeywell Sundial Plans Wiring Booklet.
