INSTALLATION
V4043H 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 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 below 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.
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.

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. Pump should run (S Plan ONLY) and boiler should
fire (S and C Plan). 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 or switch off at
programmer.
b. Set room thermostat to maximum and programmer
to ‘CENTRAL HEATING ON’.
c. Boiler should fire and pump should run. Feel pipe
approximately 12” from pump (C Plan), or valve (S
Plan) 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,
contact Honeywell. ENSURE THAT THE VALVE HEADS
HAVE FREE AIR MOVEMENT AROUND THEM.
