How to Find Maximum Valve OperatingTemperatureThe maximum
operating temperature for motorized valvesdepends on the maximum
ambient temperature at the valvelocation, and on the maximum fluid
temperature. Using thegraph in Fig. 2, find the maximum valve
operatingtemperature as follows:
� Measure the ambient temperature at the valve andlocate that
temperature on the ambient temperaturescale on the graph.
� Draw a line from the ambient temperature, parallel withthe
fluid temperature scale, to the maximum fluidtemperature line.
� Draw a line from that point down to the fluidtemperature scale
to find the maximum operatingtemperature. (Note the example shown
by the dashedline in Fig. 2.)
To find the maximum ambient temperature for a valve whenthe
fluid temperature is known, reverse the procedure.

equivalent ft (m) of pipe, orfeet of water (kPa) can be calculated
from Fig. 3 through 8as follows:
� Calculate the flow rate to heat the zone.� Determine the Cv
(kV) rating of the motorized valve.� Select the graph corresponding
to the Cv (kV) rating
(Fig. 3 through 8).� Determine the pressure drop across the
valve using
the following procedures for calculating pressure drop.
Pressure Drop in psi (kPa)� Locate the flow rate at the bottom
of the graph.� Draw a line up from the flow rate to the
intersection of
the curve.� Draw a line from the intersection to the left edge
of the
graph to determine the pressure drop in psi (kPa).
Pressure Drop in Equivalent ft (m) of Pipe
NOTE: Both 1/2 and 3/4 in. pipe conversion scales areavailable
for this determination.
� Locate the flow rate at the bottom of the graph.� Draw a line
vertically to the top of the graph.
Determine the pressure drop for either the 1/2 or 3/4in.
pipe.
Pressure Drop in ft of Water (kPa)� Locate the flow rate at the
bottom of the graph.� Draw a line up from the flow rate to the
intersection of
the curve.� Draw a line from the intersection to the right edge
of
the graph to determine pressure drop in ft of water(kPa).

INSTALLATION
When Installing this Product…1. Read these instructions
carefully. Failure to follow them
could damage the product or cause a hazardouscondition.
2. Check the ratings given in the instructions and on theproduct
to make sure the product is suitable for yourapplication.
3. Installer must be a trained, experienced
servicetechnician.
4. After installation is complete, check out productoperation as
provided in these instructions.
CAUTION1. Disconnect power supply before connecting
wiring to prevent electrical shock or equipmentdamage.
2. Normally it is not necessary to remove thepowerhead from the
valve body duringinstallation. If the valve must be disassembled,be
certain that it is reassembled with the waterflow in the direction
of the arrow. Reversal of thepowerhead results in damage to the
gear train.
3. On 24V systems, never jumper the valve coilterminals even
temporarily. This can burn out theheat anticipator in the
thermostat.
IMPORTANTUse this valve in hydronic heating systems that donot
contain dissolved oxygen in the system water.The dissolved oxygen,
which is found in systemsthat have a frequent source of makeup
water,causes the rubber plug inside the valve todeteriorate and
eventually fail.
MountingThe valve can be mounted in any position on a vertical
line.See Fig. 9. If the valve is mounted horizontally; thepowerhead
must be even with or above the center line of thepiping. Make sure
to leave enough room above thepowerhead to remove the cover for
servicing.

Mount the valve directly in the tube or pipe. Make sure thatthe
flow through the valve is in the direction indicated by thearrow
stamped on the valve body.
On diverting valves, the three fittings or ports are labeled
onthe bottom of the valve body casting. See Fig. 1. Port AB isthe
inlet port and is open at all times. Port A is closed whenthe valve
is de-energized; port B is open when the valve isde-energized.
Refer to the equipment manufacturerinstructions to determine which
port (A or B) should beconnected to the coil bypass.
Flare Fitting ModelsUse new, properly reamed pipe, free from
chips. The valvebody is threaded for standard 5/8 in. OD copper, 45
degreeSAE flare fitting nuts. These nuts are not furnished with
thevalve and must be obtained separately.
Sweat Copper Models� Use new, properly reamed pipe, free from
dents or
corrosion.� Place the valve on the pipe. Set the manual
opening
lever to MAN. OPEN position before applying heat.This protects
the plug inside the valve by removing itfrom the seat.
� Sweat the joints, keeping the outer surface free fromsolder.
DO NOT use silver solder because of the highmelting temperature
required.
To Install Replacement PowerheadSystem with Old Style Valve
Bodies (Series 1-5)To install a replacement powerhead in a system
with an oldstyle body (series 1-5), the valve body must be
converted toaccept the new powerhead using part no.
40003918Conversion Kit. The kit includes a metal plate with
adriveshaft and rubber plug, O-ring, and four screws.
IMPORTANTConverting the valve body for use with the newpowerhead
does not require removal of the valvebody from the pipeline.
However, it is necessary todrain the water from the system before
beginningthe conversion.
� Disconnect the power supply before connecting thewiring to
prevent electrical shock or equipmentdamage.
� Disconnect the leadwires to the powerhead at theterminal block
or conduit connection. Remove theconduit or cable connector if
fitted. Label each wire forrewiring later.
� Drain the water from the system.
� Remove the old powerhead from the valve body(Fig. 10):a. Place
the manual opening lever (normally closed
models only) on the old powerhead in the MAN.OPEN position (see
Fig. 10A).
b. Remove the cover (Fig. 10B).c. With the cover off, remove the
four screws
securing the powerhead to the valve body.d. Lift the powerhead
off the valve body (Fig. 10C).e. Remove the O-ring from the top of
the valve body.
� Install 40003918 Conversion Kit (Fig. 11):a. Insert the new
O-ring in the valve body.b. Place metal plate with the rubber plug
on top of
the valve body. Make sure the guide pins on theunderside of the
metal plate fit into the recesseson the valve body.
c. Secure the metal plate to the valve body with thefour screws
(two sets) provided. One set of screwshas heads with recessed
threads to insert screwsfor mounting the new powerhead; insert this
setinto the larger screw openings. The other set hasdomed heads;
insert this set into the smallerscrew openings. Each set of screws
must beinserted in opposite corners of the metal plate sothe screws
sit flat on the plate. Make sure theguide pins on the plate fit
into the recesses on thevalve body.
� Install new powerhead (see Fig. 12):a. Place the manual
opening lever (normally closed
models only) on the new powerhead in the MAN.OPEN position.
b. Fit the powerhead onto the valve body, ensuringthat the shaft
seats correctly. The powerheadshould be aligned with the manual
opening leveror slot for lever at the port A end of the valve
body.
c. Secure the powerhead to the valve body with thetwo screws
provided.
d. If fitted, reconnect the conduit or cable. Reconnectthe
leadwires at the powerhead.

OPERATION AND CHECKOUT
CAUTIONOn 24V systems, never jumper the valve coilterminals even
temporarily. This can burn out theheat anticipator in the
thermostat.
OperationAutomatic OperationOn a call for heat by the zone
thermostat, the valve opensand its auxiliary switch contacts make,
closing the circuit tothe system circulator. In a multizone system
with all the valveauxiliary switches wired in parallel, any zone
calling for heatcan operate the circulator. When the call for heat
ends, thevalve closes by integral spring return. The auxiliary
switchcontacts break the circulator circuit.
Manual OperationThe motorized valve can be opened manually by
lifting themanual opening lever over the stop and pushing slowly
andfirmly to the MAN. OPEN position. The stop permits the valveto
be locked in the open position. The valve returns toautomatic
position when the valve is energized.
Normally Closed ModelsWith the manual opener set to AUTO and the
powerheadenergized, the valve is opened as shown in Fig. 36A.
Whenthe powerhead is de-energized, a spring-return mechanismdrives
the valve to the closed position as shown in Fig. 36B.The valve can
also be opened with no electrical power bymoving the manual opening
lever over the stop and pushingslowly and firmly to the MAN. OPEN
position. The stoppermits the valve to be locked in the open
position. The valvereturns to the automatic position when the valve
isenergized.
Auxiliary switch is not energized when the valve is
manuallyopened.
Normally Open ModelsWhen the powerhead is de-energized, a
spring-returnmechanism drives the valve to the open position (Fig.
36A).When energized, the valve is closed as shown in Fig. 36B.A

Checkout� Raise the setpoint on the zone thermostat above
the
room temperature to initiate a call for heat.� Observe all
control devices—the valve should open
and the auxiliary switch should make the circuit to
thecirculator or other valve at the end of the openingstroke.
� Lower the setpoint on the zone thermostat below theroom
temperature.
� Observe the control devices. The valve should closeand the
auxiliary equipment should stop.
ServiceThis valve should be serviced by a trained,
experiencedservice technician.
1. If the valve is leaking, drain the system and check tosee if
the O-ring needs replacing.
2. If the gear train is damaged, replace the entirepowerhead
assembly. See the Installation section. Ifthe motor is burned out,
replace the motor. SeeReplacement Parts list in the TRADELINE®
Catalog.
NOTE: Honeywell zone valves are designed and tested forsilent
operation in properly designed and installedsystems; however, water
noises can occur as a resultof excessive water velocity or piping
noises canoccur in high temperature (higher than 212°F(100°C)
systems with insufficient water pressure.Valves are designed for
normal cycling operations.Product life will be shortened if
energizedcontinuously.
