INSTALLATION

INSTRUCTIONS

V4073A Motorised Mid-Position Valve

Application

The V4073A valve has been designed to control the flow of

water in a small bore domestic central heating system where

both radiator and hot water cylinder circulation are pumped.

It is typically suited for systems up to 90,000 Btu/h (26 KW).

Specifications

Voltage: 230-240V ~ 50Hz

Power consumption: 6W

Lead supplied: 1 metre, 5 core

Operating temperature range: +5 to +88°C

(Special models available for chilled water applications)

Maximum ambient temperature: +52°C

Pipe fitting sizes:

22mm & 28mm compression fitting, / " & 1" BSP

Dimensions and KV values: See diagrams

Installation

V4073A incorporates a manual

lever, the lever should normally

be in ‘AUTO’ position, but can

be moved to ‘MAN OPEN’

position for system draindown

and filling purposes only.

OPEN

Before fitting the valve, read

through the plumbing and

wiring instructions.

This product MUST be

installed by a competent

person. The installation MUST conform to I.E.E.

Regulations and with The Electricity at Work Regulations.

A Class ‘A’ switch (having contact separation of at least

3mm in all poles) must be incorporated in the fixed wiring

as a means of disconnecting the supply. The system must

be appropriately fused.

Flow

Characteristics

Plumbing

The valve MUST NOT be fitted on the return pipework

under any circumstances. Flow from the boiler must be

connected to port AB, the radiator circuit to port A and the

hot water cylinder circuit to port B.

The valve may be plumbed in at any angle but must not be

mounted so that the valve head is below the horizontal

level of the pipework. In the unlikely event of a leak a

safety hazard could result.

Do not grip the valve head while making and tightening up

plumbing connections. Attach a spanner (32mm or 1 / " AF)

onto the valve body at each port, whilst tightening up the nuts.

Tighten compression nuts enough to make a watertight seal.

TAKE CARE NOT TO OVERTIGHTEN.

Wiring

The wiring diagram above shows relevant connections to a Honeywell junction box (Part No. 42002116-001). Ensure

that each numbered, lettered or coloured wire is connected to the correct terminal in the junction box. Make sure all

connections are good and all terminal screws are firmly tightened.

Valve wiring configuration is: White = Heating on

Grey = Hot water off

Orange = Boiler and pump live

Blue

= Neutral

Green/Yellow = Earth

Notes:

a Wiring diagram shows connections to a programmer with separate control of heating and hot water.

b If single channel time clock is used, connect switched live from time clock to terminal 4 or 6 at junction box, then link

terminal 4 to terminal 6 with a link wire.

c If the programmer or time clock have no ‘Hot water OFF’ terminal then the time clock will need to be replaced.

d If replacing a 6 wire relay model valve with a non relay 5 wire valve, contact Honeywell for advice.

3 Confirm correct heating functions as follows:

Checkout procedure

To ensure the valve is plumbed and wired correctly, carry

out the following checks after filling the system and

a Turn cylinder thermostat to minimum or switch off

at programmer.

switching on the power.

b Set room thermostat to maximum and programmer to

‘CENTRAL HEATING ON’.

1 a Check manual lever is in ‘AUTO’ position.

b Check programmer has power.

c Boiler should fire and pump should run. Feel pipe

approximately 12" from port A, it should get hot.

c Check boiler is switched on and its thermostat

set to maximum.

4 Confirm valve is functioning at mid position by switching

‘HEATING ON’ and ‘HOT WATER ON’ at the programmer.

Set both thermostat to maximum, feel pipes approximately

12" from both ports A and B. Both pipes should get hot.

2 Confirm correct hot water functions as follows:

a Turn room thermostat to minimum setting or switch off

at programmer.

Completion

b Set cylinder thermostat to maximum and programmer to

Reset both thermostats to temperature required, normally

60°C for cylinder thermostat and 20°C for room thermostat.

Return programmer to ‘Auto’ or mode selected by

householder. Full installation, wiring and operating instructions

for SUNDIAL products are included in every product pack. For

special wiring diagrams or applications, contact Honeywell.
