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).

V4044C DIVERTER VALVE
INSTALLATION
V4044C 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.
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 3 mm
in all poles) must be incorporated in the fixed wiring as a
means of disconnecting the supply. The system must be
appropriately fused.
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 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 (32 mm or 1 1/4” 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 (Fig. 3) 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:
Brown = Motor open
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.

CHECKOUT PROCEDURE
To ensure the valve is plumbed and wired correctly, carry out
the following checks after filling the system and switching on
the power:
1.
a. Check the manual lever is in ‘AUTO’ position.
b. Check programmer has power.
c. Check boiler is switched on and its thermostat set to
maximum.
2. Confirm correct hot water functions as follows:
a. Turn room thermostat to minimum setting or switch
off at programmer.
b. Set cylinder thermostat to maximum and program-
mer to ‘HOT WATER ON’.
c. Boiler should fire and pump should run. Feel pipe
approximately 12” from valve port B, it should get
hot.
3. Confirm correct heating functions as follows:
a. Turn cylinder thermostat to minimum.
b. Set room thermostat to maximum and programmer
to ‘HOT WATER AND CENTRAL HEATING ON’.
c. Boiler should fire and pump should run. Feel pipe
approximately 12” from port A, it should get hot.
COMPLETION
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,
