3 - Way, Balanced Hydronic Valves
These two position 3 way hydronic valves are intended for use in a
normal indoor environment to control the flow of hot and/or cold water,
or glycol solution to 50% concentration.
They consist of an actuator, valve and replaceable valve cartridge
assembly. These valves can be piped for either diverting or mixing
valve applications in central heating and/or cooling systems; or for
individual fan coil, radiator or convector applications.
Depending on the model selected they can be controlled by either a
low or line voltage SPST OR SPDT controller such as a room
thermostat, aquastat or flow switch.

Flow: Bottom port is marked AB. End ports are marked A & B. Port A is
closed and port B open with the stem up position (Figure 1). Flow can
be A or B to AB for mixing, or AB to A or B for diverting.
PLUMBING
!
Do not use boiler additives, solder flux and wetted materials
which are petroleum based or contain mineral oil, hydrocar­
bons, or ethylene glycol acetate. Compounds which can be
used, with minimum 50% water dilution, are diethylene
glycol, ethylene glycol, and propylene glycol (antifreeze
solutions).
AB <-> B
A
IMPORTANT:
B
Put the VC actuator manual lever in the manual open or the fully
open (down) position to allow initial system flushing with the
actuator mounted. This may be done without electrical hook-up.
Alternatively, reusable flush caps, part # 272866B, may be
purchased separately for use in initial flushing of dirty hydronic
systems.
AB <-> A
Do not use boiler additives, solder flux and wetted materials
which are petroleum based or contain mineral oil, hydrocar­
bons, or ethylene glycol acetate. Compounds which can be
used, with minimum 50% water dilution, are diethylene
glycol, ethylene glycol, and propylene glycol (antifreeze
solutions).
AB
A
B
The valve may be plumbed in any angle but preferably not with the
actuator below horizontal level of the body. Make sure there is enough
room around the actuator for servicing or replacement.
AB
For use in diverting applications, the valve is installed with the flow
water entering through bottom port AB, and diverting through end ports
A or B. In mixing applications the valve is installed with inlet to A or B
and outlet through AB.
Mount the valve directly in the tube or pipe. Do not grip the actuator
while making and tightening up plumbing connections. Either hold valve
body in your hand or attach adjustable spanner (38 mm or 1-1/2")
across hexagonal or flat faces on the valve body. (Figure 2)
Figure 1 : Fluid flow direction of 3-way valve
MANUAL OPENER
The manual opener can be manipulated only when in the up position.
The "A" port can be manually opened by firmly pushing the red
manual lever down to midway and in. In this position both the "A" and
"B" ports are open, and with auxiliary switch models the switch is
closed. This "manual open" position may be used for filling, venting
and draining the system, or for opening the valve in case of power
failure. The valve can be restored manually to the closed position by
depressing the red manual lever lightly and then pulling the lever out.
The valve and actuator will return to the automatic position when
power is restored. Note: If the valve is powered open, it can not
bemanually closed unless actuator is removed.
If assembly valve train on a bench, take care not to deform body with vice.
Do not place the raised "H" logo between the jaws of the vice. Excess
jaw force can deform the body.
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-person.
4. Always conduct a thorough checkout when installation is com­
pleted.
5. While not necessary to remove the actuator from the body, it can be
removed for ease of installation. The actuator can be installed in
any position to suit the most convenient wiring mode.
6. An extra 25 mm head clearance is required to remove the actuator.
!
CAUTION:
Disconnect power supply before connecting wiring to prevent
electrical shock and equipment damage.
On 24V systems, never jumper the valve coil terminals, even
temporarily. This may damage the thermostat.
Figure 2: Plumbing of the VC valve.

COMPRESSION MODELS
For compression fitted models, tighten the compression nuts enough
to make a watertight seal. TAKE CARE NOT TO OVER TIGHTEN.
Maximum torque limit is 33 ft-lb for the 22 mm compression fitting,
and 48 ft-lb for the 28 mm compression fitting.
SWEAT MODELS
On sweat fitted valves, the cartridge is shipped loose to avoid being
damaged during the solder operation.
1. Remove valve actuator from body and solder the connecting pipes
in accordance with normal soldering practices.
2. After soldering and valve has cooled, remove cartridge assembly
from plastic bag, insert into the valve body and tighten down with
enclosed wrench until it bottoms out. DO NOT OVER TIGHTEN
(maximum torque is 40 in-lb). The top surface of the cartridge will
be flush with the top edge of the body casting.
3. Replace valve actuator.
WIRING
NOTE: Each 3-wire (SPDT) actuator must have individual SPDT controller.
Use series 40 or 80 for single controller to control multiple valves.
VC2114 and VC8114 actuators must be used with separately­
powered (hardwired) electronic controllers. Their sustained current
draw is too low for power stealing (parasitic power) thermostats
or series anticipators of electromechanical thermostats.
Figures 4A,4B,5A,5B show wiring connections. Port "A" open and
closed denote valve open and closed positions respectively. On auxiliary
switch models, terminal 4 (grey wire) contact makes at the end of the Port A
opening stroke. On Molex™ connector models, valve & auxiliary switch
voltage must be the same to meet approval requirement. For mixed line
voltage and 24 Vac (Safety Extra Low Voltage) application, the cable
version is recommended. auxiliary switch voltages must be the same to
meet approval requirement. For mixed line voltage and 24 Vac (Safety Extra
Low Voltage) application, the cable assembly version is recommended.
TO INSTALL REPLACEMENT ACTUATOR
5
NOTE: Installation of a new actuator does not require draining
the system provided the valve body and valve cartridge
assembly remain in the pipeline.
1. Check replacement part number and voltage ratings for match with
old device.
2. Disconnect power supply before servicing to avoid electrical shock
or equipment damage.
3. Disconnect leadwires to actuator, or depress tab on Molex™
connector and remove. Where appropriate, label wires for rewiring.
4. The actuator head is automatically latched to the valve. To remove,
press up on the latch mechanism located directly below the red
manual open lever with thumb (See Figure 3 below). Simultane­
ously press the actuator down towards the body with moderate
hand force and turn the actuator counter-clockwise by 1/8 turn (45
degrees). Lift the actuator off the valve body.
NOTE: The actuator can also be installed at right angles to the
valve body but in this position the latch mechanism is not engaged.
5. Install the new actuator by reversing the process in (4).
6. Reconnect leadwires or Molex™ connector.
7. Restore power, and checkout operation.

WHEN USED WITH SPDT (3-WIRE) CONTROLLER (Fig. 6): On a call
for heat, the NO thermostat contacts close, the valve opens port "A" and
closes port "B". When the valve reaches port "A" fully open position, the
cam actuated SW1 closes and SW2 opens. When the need for heat is
satisfied, the NC thermostat contacts close, energising the valve through
SW1 to close port "A". When the port "A" is fully closed, the cam actuated
SW2 closes and SW1 opens anticipating the next call for heat cycle.
On power failure, the valve will stay at whatever position it was in when the
power was interrupted. When power is restored, the valve will respond to the
controller demand.

3
This valve should be serviced by a trained, experienced service
technician.
1. If the valve is leaking , drain system OR isolate valve from the
system. Do not remove valve body from plumbing.
2. Check to see if the cartridge needs to be replaced.
3. If the motor or other internal parts of the actuator is damaged,
replace the entire actuator assembly.
NOTE: Honeywell hydronic 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.
Do not use boiler additives which are petroleum based or contain
mineral oil, hydrocarbons, or ethylene glycol acetate. Compounds
which can be used, with minimum 50% water dilution, are diethylene
glycol, ethylene glycol, and propylene glycol.
