VC6800, VC6900 Series
Floating Control Valves
GENERAL
The VC6800/VC6900 Series Modulating Control Valves
provide optimum control of hot and/or chilled water flow
in various heating and cooling applications, such as fan
coil units, reheat coils and perimeter heating systems.
The VC hydronic valve consists of a valve body and
replaceable characterized cartridge assembly. When used
with a VC6800/VC6900 series actuator, the valve provides
linear flow in either diverting or mixing applications. They
are designed to provide sinusoidal valve actuator travel,
and therefore operate silently and resist water hammer.
Compatible with 24 Vac, 3-wire signal, the VC series valve
actuator is used with either a single pole double throw
two-position controller for on-off control, or a floating
controller for modulating control. These actuators have
conformal coated printed circuit boards for humidity
resistance. Through an internal switching mechanism, the
actuator takes power only while driving the valve to the
commanded position.
FEATURES
• All actuators are interchangeable and suitable for all
valves, 1/2" through 1", providing maximum
installation flexibility with minimum stocking
requirements.
• A locking tab secures the actuator to the body of the
valve.
• Multi-directional actuator mount allows for 4
different wiring orientations, thus providing ease of
wiring and service.
• Actuator is constructed of moisture and humidity
resistant materials.
• Long service life because the actuator motor
de-energizes when not in motion.
• Manual opener and position indicator. This "manual
opener" position may be used for filling, venting, and
draining the system.
• Bayonet-mount for actuator head. Actuator can be
installed after plumbing work has been completed,
which makes for more efficient on-site installation.
• Body dimensions are comparable to existing
products (V4043/4044 and V8043/8044), and in
most cases can be interchanged.
• Sweat-fitted valves are supplied with the cartridge
loose, to facilitate soldering operations (an
installation tool is included).
• In this balanced valve design, the internal piston
moves up and down, across the water flow. The
actuator provides sinusoidal piston travel action for
"soft" shut-off and open, to eliminate water hammer
in most applications.
• In 2-way valves, flow is bi-directional.
• In 3-way valves, flow can be mixing or diverting.

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. Always conduct a thorough checkout when
installation is completed.
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 of the four
orientations to suit the most convenient wiring
direction. Actuator latching mechanism works only
when the lengths of the actuator and the valve body
are parallel to each other.
6. An extra 1” (25 mm) head clearance is required to
remove the actuator.
CAUTION
Disconnect power supply before connecting
wiring to prevent electrical shock and equipment
damage.
Never jumper the valve coil terminals, even
temporarily. This may damage the thermostat.
PLUMBING
The valve may be plumbed in any angle, including vertical
piping, but preferably not with the actuator below the
horizontal level of valve body. Make sure there is enough
room around the actuator for servicing or replacement.
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 the
hexagonal or flat faces on the valve body. (Fig. 4).
Fig. 4. 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 45 Nm (33 ft-lb) for the 22 mm
compression fitting, and 65 Nm (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
(part# 40007029-002) until it bottoms out.
DO NOT OVER TIGHTEN (maximum torque is
4.5 Nm [40 in-lb]). The top surface of the cartridge
will be flush with the top edge of the body casting.
3. Replace valve actuator.

TO INSTALL REPLACEMENT ACTUATOR
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 white manual open lever
with thumb (See Fig. 5). Simultaneously press the
actuator down towards the body with moderate hand
force and turn the actuator counter-clockwise by
1/8 turn (45 degrees). Lift 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 will not engage.
5.
Install the new actuator by reversing the process in (4).
6. Reconnect leadwires or Molex™ connector.
7. Restore power, and check out operation.
Fig. 5. Latch Mechanism to detach Actuator
MANUAL OPENER
The manual opener can be manipulated only when in the
up position. The “A” port can be opened by firmly pushing
the white 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, or 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 white 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 be
manually closed unless actuator is removed.

WIRING
One controller and a separate transformer is required to
operate each valve.
Figures 6A and 6B show wiring connections. Port “A” open
and closed denote valve open and closed positions
respectively. On auxiliary switch models, contact makes in
between (NC) terminal 1 (orange wire) and (NO) terminal 4
(gray wire) in mid-range of opening cycle. On Molex™
connector models, valve and auxiliary switch voltage must
be the same to meet approval requirement. When mixing
line voltage and 24 Vac (Safety Extra Low Voltage)
application together, the cable version must be used.

OPERATIONS
WITH SERIES 60 FLOATING CONTROLLER
(refer to Fig. 7)
The series 60 floating controller is an SPDT controller with
a center-off position. On a change in temperature from the
set point, the controller will close the NO or NC contacts,
driving the valve to an intermediate position until a further
change at the controller. The valve is set between the
limits of the controller to satisfy various load
requirements. In the event of a power failure, the valve will
stay at whatever position it was in when the power was
interrupted. When power is restored, the valve will the
valve will respond to the controller demand.

SERVICE
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 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: Resideo 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 also occur in high temperature
(over 212 °F [100 °C]) systems with insufficient
water pressure.
IMPORTANT
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 (antifreeze solutions).
CHECKOUT
1. Raise the set point of the thermostat above room
temperature to initiate a call for heat.
2. Observe all control devices - 2 way valve should
open. Port A in 3 way valve should open, and port B
should close. The auxiliary switch (if present) should
operate and make at the end of the opening stroke,
activating the auxiliary equipment.
3. Lower the set point of the zone thermostat below
room temperature.
4. Observe the control devices. 2 way valve should
close. Port A in 3 way valve should close, and port B
should open. All auxiliary equipment should stop.
USE 105°C (222°F) RATED SUPPLY WIRES ONLY.
