INSTALLATION INSTRUCTIONS
APPLICATION
The 40003916 is a replacement powerhead for the
V4043, V4044, V8043, and V8044 fan coil and zone
valves. See Table 1. The powerhead includes the motor,
housing, and 2 mounting screws. Models are available
for low or line voltage applications.
This powerhead is for use with new style valve bodies
(series 6) or old style valve bodies (series 1-5) that have
been converted to accept this powerhead. The new style
valve bodies are identified with a sideways 6 on the
powerhead after the OS number and an indent under the
OS number on the powerhead. See Fig.1. If using an old
style valve, the valve must be converted using Part No.
40003918 (order separately).
Fig. 1. Sideways number after OS number on
powerhead identifies valve series.
INSTALLATION
When Installing this Product...
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a hazardous condition.
2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for
your application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
Disconnect power supply before connecting
wiring to prevent electrical shock or
equipment damage.
SYSTEMS WITH OLD STYLE VALVE BODIES
(SERIES 1-5)
To install this powerhead in a system with an old style
valve body (series 1-5), the valve body must be
converted to accept 40003916 Powerhead using Part
No. 40003918 Conversion Kit. The kit includes a metal
plate with driveshaft and rubber plug, O-ring, and 4
screws.
IMPORTANT
Converting the valve body for use with the new
powerhead does not require removal of the
valve body from the pipeline. It is, however, necessary to drain the water from the system
before beginning the conversion.
1. Disconnect power supply before connecting wiring
to prevent electrical shock or equipment damage.
2. Disconnect the leadwires to the powerhead at terminal block or conduit connection. Remove conduit
or cable connector if fitted. Label each wire for
rewiring later.
3. Drain the water from the system.
4. Remove the old powerhead from the valve body.

5. Install 40003918 Conversion Kit (See Fig. 3).
— Insert new O-ring in the valve body.
— Place metal plate with rubber plug on top of
valve body. Make sure the guide pins on the
underside of metal plate fit into recesses on
valve body.
— Secure the metal plate to the valve body with
the 4 screws (2 sets) provided. One set of
screws has heads with recessed threads to
insert screws for mounting powerhead; insert
this set in the larger screw openings. The
other set has domed heads; insert this set in
the smaller screw openings. Each set must
be inserted in the opposite corners of the
metal plate so screws sit flat on the plate.
Make sure the guide pins on the plate fit into
recesses on valve body.

Systems with new style valve bodies (Series 6)
IMPORTANT
On a new style valve body or a valve body that
has been converted to accept this new powerhead, it is not necessary to drain the system if
the valve body remains in the pipeline.
1. Disconnect power supply before connecting wiring
to prevent electrical shock or equipment damage.
2. Disconnect leadwires to powerhead at terminal
block or conduit connection. Disconnect conduit or
cable connector if fitted. Label each wire for rewiring later.
3. Remove old powerhead (See Fig. 5).
— Place the manual opening lever (normally
closed models only) on the old powerhead in
the MAN. OPEN position. (Fig. 5A.)
— Remove screw securing the cover to the pow-
erhead. Lift powerhead cover off. (Fig. 5B.)
— Remove the 2 screws securing the power-
head to the valve body. (Fig. 4.)
— Lift the powerhead off the valve body.

OPERATION AND CHECKOUT
On 24 V systems, never jumper the valve coil
terminals even temporarily. This may burn out
the heat anticipator in the thermostat.
Operation
Normally closed models
With the manual opening lever set to AUTO and the
powerhead energized, the valve is opened as shown in
Fig. 6A. When the powerhead is de-energized, a springreturn mechanism drives the valve to the closed position
as shown in Fig. 6B. The valve can also be opened with
no electrical power by moving the manual opening lever
over the stop and pushing slowly and firmly to the MAN.
OPEN position. The stop permits the valve to be locked
in the open position. The valve will return to automatic
position when the valve is energized.
Auxiliary switch is not energized when valve is manually
opened.
Normally open models
When the powerhead is de-energized, a spring-return
mechanism drives the valve to the open position (Fig.
6A). When energized, the valve is closed as shown in
Fig. 6B. A reverse-acting thermostat is required to control
a normally open valve.
NOTE: Inlet Port is stamped “A”, Outlet Port is stamped
“B” on the valve body.

1. Raise the set point on the zone thermostat above
room temperature to initiate a call for heat.
2. Observe all control devices - the valve should open
and the auxiliary switch should make the circuit to
the circulator or other valve at the end of the opening stroke.
3. Lower the set point on the zone thermostat below
room temperature.
4. Observe the control devices. The valve should
close and auxiliary equipment should stop.
Service
This valve should be serviced by a trained, experienced
service technician.
1. If the valve is leaking, drain the system and check
to see if the O-ring needs to be replaced.
2. If the gear train is damaged, replace the entire
powerhead assembly. See Installation. If motor is
burned out, replace motor. See Replacement Parts
list in TRADELINE® Catalog.
NOTE: Honeywell zone valves are designed and tested
for silent operation in properly designed and
installed systems. However, water noises may
occur as a result of excessive water velocity.
Piping noises may occur in high temperature
(over 212° F [100° C]) systems with insufficient
water pressure.
