APPLICATION
The V4073A 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 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 (42002116-001) together with the Honeywell
Sundial Plans Wiring Booklet.
