F4-CV Series VAV Terminal Equipment
Controllers Installation Guide
Application
The CV series controllers are designed for variable air
volume (VAV) box applications.
CV series controllers feature 14 preloaded standard
applications to allow this controller to operate
standard VAV box equipment with a proven energy-
efficient sequence of operation, without the need for
programming. For information on configuring a CV series
controller to use a preloaded application, see Setting a
preloaded application. These controllers are also fully
programmable, using the Controller Configuration Tool
(CCT), providing the flexibility to create custom control
sequences.
CV series controllers feature an integral damper actuator,
a digital Differential Pressure Transmitter (DPT) sensor,
and a 32-bit microprocessor. The CVM03050-0P and
CVE03050-0P models feature an integral potentiometer to
sense actual VAV box damper position.
CV series controllers also include an integral real-time
clock, which enables the controllers to monitor and
control schedules, calendars, and trends, and operate
for extended periods of time as stand-alone controllers
when offline from the Facility Explorer system network.
These controllers connect easily to the wired and
wireless network sensors for zone and discharge air
temperature sensing. Their small package size facilitates
quick field installation and efficient use of space without
compromising control performance.

Communications protocols
CV series controllers can communicate using multiple
communication protocols depending on model and
configuration. The CVE controllers communicate using
the BACnet/IP communication protocol. CVM controllers
communicate using the BACnet MS/TP communications
protocols, with the addition of ZFR183x Pro Wireless
Field Bus Routers. Equipment Controllers in BACnet/IP or
BACnet/MSTP communication mode are BACnet network-
compliant devices. The BACnet protocol is a standard
for ANSI, ASHRAE, and the International Standards
Organization (ISO) for building controls.
To configure CVM controllers to communicate using
the wireless communications protocol, see Configuring
wireless communications (CVM models only).

F4-CV Series VAV Terminal Equipment Controllers Installation Guide2

Mounting
Observe the following guidelines when mounting a CVM/
CVE controller:
• Ensure that the mounting surface can support the
controller and any user-supplied enclosure.
• Mount the controller on a hard, even surface whenever
possible.
• Use shims or washers to mount the controller securely
and evenly on the mounting surface.
• Mount the controller in an area free of corrosive vapors
that matches the ambient conditions specified in the
Technical specifications section.
• Provide sufficient space around the controller for cable
and wire connections and adequate ventilation through
the controller (at least 50 mm [2 in.] on the top, bottom,
sides, and front of the controllers).
• Do not mount the controller in areas where
electromagnetic emissions from other devices or wiring
can interfere with controller communication.
• Avoid mounting the controller on surfaces with
excessive vibration.
Important: When the air supply to the VAV box is
below 10°C (50°F), make sure that any condensation
on the VAV box, particularly on the damper shaft,
does not enter the controller electronics. Mount
the controller vertically above the damper shaft to
allow any shaft condensation to fall away from the
controller. Additional measures may be required in
some installations.
On panel or enclosure mount applications, observe these
additional guidelines:
• Do not install the controller in an airtight enclosure.
• Mount the controller so that the enclosure walls do
not obstruct cover removal or ventilation through the
controller.
• Mount the controller so that the power transformer
and other devices do not radiate excessive heat to the
controller.
Figure 4: Controller mounting positions
To mount the CVM/CVE controllers, complete the
following steps:
1. Set all the switches on the equipment controller to
their known settings.
2. Place the controller in the proper mounting position
on the damper shaft so that the wiring connections
are easily accessible. Make sure the controller base is
parallel to the VAV box (perpendicular to the damper
shaft). If needed, use a spacer to offset tipping of the
controller caused by the shaft bushings.
Note: Use the alignment marks to center the
captive spacer to ensure sufficient CVM/CVE
movement in either direction.
3. Secure the self-drilling No.10 screw through the
captive spacer with a power screwdriver and 100mm
(4in.) extension socket. Otherwise, use a punch to
mark the position of the shoulder washer, and then
drill a hole into the VAV box using a 3.5mm (9/64in.)
drill bit. Insert the mounting screw and tighten
against the spacer.
Important: Do not overtighten the screw, or
the threads may strip. If mounting to the VAV
box, make sure the screws do not interfere with
damper blade movement.
4. Locate the damper position using the typical
marking on the end of the damper shaft as shown in
the figure below.
Figure 5: Typical damper end shaft icons
5. Note the direction, clockwise (CW) or
counterclockwise (CCW), required to close the
damper. Grasp the damper shaft firmly with pliers,
and either manually close the damper for 90° boxes
or manually open the damper for 45° or 60° boxes.
6. Push down and hold the Manual Override button
and turn the controller coupler until it contacts the
mechanical end-stop at either the full-closed (90°
boxes) or full-open (45° and 60° boxes) position.
7. If the damper for a 90° box closes CCW, rotate the
coupler to the CCW mechanical limit. If the damper
for a 90° box closes CW, rotate the coupler to the CW
mechanical limit. The open end-stop is automatically
set for 90° boxes. For 45° and 60° boxes, you must
provide hard stops at both full-closed and full-open
damper positions. If you install the controller at the
full-open position, the controller provides the open
stop for 45° and 60° boxes. The closed damper seal
provides the full-closed stop.
F4-CV Series VAV Terminal Equipment Controllers Installation Guide 3

Note: The integrated actuator has a stroke
time of 60 seconds for 90° of travel with a 60Hz
power source. The stroke time is the amount
of time (in seconds) that it takes the actuator
to move from the fully closed to fully opened
position or from fully open to fully closed
position. For proper operation, the actuator
stroke time must be configured in the CCT
application based on the actual time it takes
the actuator to drive the damper. The default
setting is 60 seconds (for 90° VAV boxes). For
45° and 60° VAV boxes, the actuator stroke time
must be adjusted. Refer to Controller Tool Help
(LIT-12011147) for instructions on setting the
actuator stroke time in the application.
8. All models are compact in size and are easily
installed on VAV boxes. The models have either a
round shaft up to 13 mm in diameter or a 10 mm
square shaft. Tighten the square coupler bolt to the
shaft using an 8 mm (5/16 in.) wrench or 10 mm (3/8
in.) 12-point socket. Tighten to 10.5 to 11.5 N·m (95 to
105 lb·in).
9. Loop the pneumatic tubing (supplied by field
personnel) to include a trap for condensation. Attach
the needed length of tubing (supplied and installed
by field personnel) to the dual port fitting on the
controller and the other ends of the tubing to the
pressure transducer in the VAV box application .
Note: The CVM/CVE uses a digital pressure
sensor with bidirectional flow operation, which
allows you to connect the high- and low-
pressure DP tubes to either barbed fitting
on the controller. You do not need to make a
specific high- or low-side connection when you
attach the tubing to the barbed fittings on the
CVM/CVE.
10. Push the Manual Override button, and turn the
actuator coupling manually to ensure that the
actuator can rotate from full-closed to full-open
positions without binding.
11. Complete the mounting by rotating the damper to
the full-open position.
CAUTION
Risk of Property Damage.
Rotate the damper to the full-open position before
starting the air handler. Failure to rotate the damper to
the full-open position may result in damage to the VAV
box or ductwork when the air handler is started.
ATTENTION
Risque de dégâts matériels.

Wiring
Observe the following guidelines when wiring a CVM/CVE
controller:
CAUTION
Risk of Electric Shock.
Disconnect the power supply before making electrical
connections to avoid electric shock.
ATTENTION
Risque de décharge électrique.
Débrancher l'alimentation avant de réaliser tout
raccordement électrique afin d'éviter tout risque de

Important: Do not connect supply power to the
controller before finishing wiring and checking all
wiring connections. Short circuits or improperly
connected wires can result in damage to the
controller and void any warranty.
Important: Do not exceed the controller electrical
ratings. Exceeding controller electrical ratings can
result in permanent damage to the controller and
void any warranty.
Important: Use copper conductors only. Make
all wiring in accordance with local, national, and
regional regulations.
Important: Electrostatic discharge can damage
controller components. Use proper electrostatic
discharge precautions during installation, setup, and
servicing to avoid damaging the controller.
For information on configuring and wiring a BACnet/
IP network, refer to theFX MS/TP Communications Bus
Technical Bulletin (LIT-12011670).
F4-CV Series VAV Terminal Equipment Controllers Installation Guide4

Terminal blocks and bus ports
See Physical features for terminal block and bus port
locations on the CVM/CVE controllers. Observe the
following guidelines when wiring a CVM/CVE controller.
Input and Output terminal blocks
CV series controllers have removable input and output
terminal blocks. The input terminals are located on the
bottom of the controller and output terminal blocks are
located on the top of the controller. For information about
removing a terminal block, see Removing a terminal
block. For more information about I/O terminal functions,
requirements, and ratings, see Table 5.
BACnet/IP Ethernet Network Topology for
CVE controllers
CVE controllers may be connected to a BACnet/IP building
automation network in multiple ways: as daisy-chained
devices, as part of a star (also called home run) type
network, or as part of a ring network.
To daisy-chain FX-PCV1930 controllers, connect the
controllers to the bus supervisor in a chain with the
Ethernet cable connecting to the FX-PCV1930 at the ETH-1
or ETH-2 port, and connecting to the next device from the
other port. Benefits of daisy-chained networks are that
they require less physical wiring and new devices can be
added easily to the network.
In a star network, each FX-PCV1930 controller is
connected by Ethernet cable directly back to a main
switch. This configuration reduces the possibility of
network failure but requires more wiring to install.
A ring network is a chain of controllers virtually closed
by a software component in an Ethernet switch. Not
all switches support the ring topology. The dual-port
controller from Johnson Controls supports Media
Redundancy Protocol (MRP). With MRP, a ring of Ethernet
devices can overcome any single communication failure,
with a recovery time faster than a non-ring (daisy chain or
star) architecture.
For more information on network topologies for IP
Controllers, see Facility Explorer IP Networks for BACnet/IP
Controllers Configuration Guide (LIT-12012980).
FC Bus terminal block on CVM controllers
The FC Bus terminal block is a blue, removable, 4-pin
terminal block that fits into a board-mounted pin header.
When connecting the CVM to the FC Bus, wire the bus
terminal blocks on the controller and other FC Bus devices
in a daisy-chain configuration using 3-wire twisted,
shielded cable as shown in Figure 6. For more information
about FC Bus terminal functions, requirements, and
ratings, see Table 7.

Wireless Transmitter, and NS Series sensors. The modular
FC Bus port provides a connection for the Bluetooth
Commissioning Converter and the FX-ZFR Wireless Router.
Note: Do not use the modular SA Bus port and the
terminal block SA Bus simultaneously. Only use one
of these connections at a time.
Supply power terminal block
The 24 VAC supply power terminal block is a gray,
removable, 2-pin terminal block that fits into a board-
mounted pin header on the upper left of the controller.
Wire the 24 VAC supply power wires from the transformer
to the HOT and COM terminals on the terminal block as
shown in Figure 9. For more information about Supply
Power terminal functions, requirements, and ratings, see
Table 7.

Note: The supply power wire colors may be different
on transformers from other manufacturers. Refer to
the transformer manufacturer’s instructions and the
project installation drawings for wiring details.
Important: Connect 24 VAC supply power to
the controller and all other network devices so
that transformer phasing is uniform across the
network devices. Powering network devices with
uniform 24 VAC supply power phasing reduces
noise, interference, and ground loop problems.
The controller does not require an earth ground
connection. However, when grounding the
secondary of the 24 VAC transformer is required,
only one connection to ground must be made near
the transformer. See Figure 10.
Figure 10: Transformer grounding
CAUTION
Risk of Property Damage:
Do not apply power to the system before checking all
wiring connections. Improper wiring of this terminal
may cause a short circuit across the 24 VAC power
supply. A short circuit may result in a tripped circuit
breaker or blown fuse. If using a transformer with a
built-in fuse, the transformer may need to be replaced.
ATTENTION
Risque de dommages matériels:
Ne mettez pas l’appareil sous tension avant d’avoir
vérifié toutes les connexions du câblage. Le câblage
inadéquat de cette borne peut causer un court-
circuit sur l’alimentation électrique de 24 V c. Un
court-circuit peut causer le déclenchement du
disjoncteur ou le grillage d’un fusible. Si vous utilisez
un transformateur avec un fusible intégré, vous
pourriez devoir remplacer le transformateur.
To wire the controller, complete the following steps:
1. Terminate wiring according to the appropriate figure
in Termination diagrams.
2. Wire network sensors and other devices to the SA
Bus.
3. Ensure that the CVM03050 is assigned a device
address and the CVE03050 is assigned a controller
number, using the rotary switches. See .
4. Connect the controller to 24 VAC, Class 2 power.
Note: If you are using the CVM03050 controller with
the Wireless Field Bus System, refer to the WNC1800/
FX-ZFR182x Pro Series Wireless Field Bus System Bulletin
(LIT-12012378) or the FX-ZFR Series Wireless Field Bus
System Bulletin (LIT-12011660).

For more information about the FX-ZFR 1800 Wireless
Field Bus system, refer to the FX-ZFR Series Wireless Field
Bus System Bulletin (LIT-12011660). For more information
on the FX-ZFR Pro Wireless Field Bus system, refer to the
WNC1800/FX-ZFR182x Pro Series Wireless Field Bus System
Bulletin (LIT-12012378).
Setting the device address on CGM
models
The CGM controllers are manager devices on MS/TP (FC
or SA) Buses. Before you operate controllers on a bus,
you must set a valid and unique device address for each
controller on the bus.
The following table describes the valid rotary switch
device addresses for communications bus applications.
FC Bus communication
mode
Valid device address range
Wired MS/TP
communication
4-127
Note: Addresses 0-3 are
reserved and not for use on
equipment controllers.
The device address is a decimal address set using three
rotary switches located at the top of the controller. The
numbers are ordered from left to right, most significant
bit (MSB) to least significant bit (LSB) when the controller
is oriented. . In the following figure, the switches are set
to 1 2 3, designating this controller's device address as
123.
F4-CV Series VAV Terminal Equipment Controllers Installation Guide14

Figure 12: Rotary switch block
The device address must match the device address
defined in the Controller Configuration Tool (CCT) under
Define Hardware > Network Settings.
To set the device addresses on controllers, complete the
following steps:
1. Set a unique and sequential device address for each
of the devices connected on the FC or SA, starting
with device address 4.
2. To ensure the best bus performance, set sequential
device addresses with no gaps in the device address
range (4, 5, 6, 7, 8, 9, and so on). The devices do not
need to be physically connected on the bus in their
numerical device address order.
3. Write each controller's device address on the white
label below the Device Address Rotary Switch Block
on the controller's cover.
Removing a terminal block
About this task:
To remove a terminal block from the circuit board,
complete the following steps:
Note: You need a flat blade screwdriver to remove
the terminal block.
1. To prevent any possibility of damage from an
accidental short, remove power from the
controller.
2. Underneath the terminal block, in the small gap
between the bottom of the terminal block and
the circuit board, insert the flat blade of the
screwdriver.
Figure 13: Terminal block
3. To detach the left-hand side of the terminal block,
position the flat blade underneath the terminal
block to the left, and push down the screwdriver
handle. When you do this, you are using the
screwdriver as a lever to pry up the terminal block.
4. To detach the right-hand side of the terminal block,
position the flat blade underneath the terminal
block to the right, and push down the screwdriver
handle.
5. If necessary, repeat steps 3 and 4 until the terminal
block is removed.
Setting the End-of-Line (EOL) switch
(CVM models only)
Each CVM controller has an EOL switch, which, when
set to ON (up), sets the CVM controller as a terminating
device on the bus. See Physical features for the EOL switch
location. The default EOL switch position is OFF (down).
Figure 14: End-of-Line Switch Positions
To set the EOL switch on a CVM controller, complete the
following steps:
1. Determine the physical location of the controller on
the FC Bus.
2. Determine if the controller must be set as a
terminating device on the bus.
Note: For detailed information about EOL
termination rules and EOL switch settings on FC
Buses, refer to the FX MS/TP Communications Bus
Technical Bulletin (LIT-12011670).
3. If the controller is a terminating device on the FC
Bus, set the EOL switch to ON. If the controller is not
a terminating device on the bus, set the EOL switch
to OFF.
When a controller is connected to power with its EOL
switch set to ON, the amber EOL LED on the controller
cover is illuminated.
Input and output wiring validation
The controllers ship with a cooling only, warm or cool
adjust application loaded by default. You can use this
default application to perform wiring verification using
the MAP Gateway, FX-DLK03050, or the FX-DIS1710-0 local
controller display.
To perform wiring validation, ensure that you set the
rotary switches to the desired address or controller
number and wire the input and output terminals. Apply
power to the controller. The Fault LED behaves the same
as it does during normal application load. When the Fault
LED turns off, connect to the device with either a MAP
Gateway, FX-DLK03050, or FX-DIS1710-0 Local Display to
view the points in the controller.
F4-CV Series VAV Terminal Equipment Controllers Installation Guide 15

Commissioning the controllers
To commission the controller, use the following
procedure:
1. With the desired application loaded in the controller,
commission the VAV Box. Refer to the Controller Tool
Help (LIT-12011147).
2. Perform airflow balancing on the VAV box. Refer

Troubleshooting equipment controllers
Table 10 provides LED status indicator information for troubleshooting the controller. General troubleshooting provides
some additional troubleshooting information for possible problems.
Note: If you experience short circuits in the 24 VAC power supply causing protective devices such as breakers or
fuses to trip, make sure that the power connections on the controller are not reversed. The most common cause
of this problem is when the 24 VAC power supply on the controller is reversed but not reversed on a connected
secondary device.

General troubleshooting
Table 11: Troubleshooting
Problem Possible cause and correction Verification
Controller is OFF.
• Transformer has tripped:
• Power is at Primary of
Transformer, 0V at Secondary.
• Breaker/Fuse has tripped:
• Power is at Primary of
Transformer, 24V at Secondary,
0V at Fuse/Breaker.
Cause:
1. Transformer is shorted.
2. 24 VAC powered sensor is not
wired with the same polarity as the
controller.
3. SA Bus device is not wired with the
same polarity as the controller.
Correction:
1. Ensure polarity of ~24 V COM / UI-C /
+ 15VC/SA BUS COM on the controller,
auxiliary devices, and I/O is the same.
2. Ensure BO-1, BO-2, and BO-3
terminals of binary outputs are not
connected to ~24 VAC COM, and verify
that BO-C terminals are not connected
to ~24 VAC HOT (these terminals are
internally sourced).
3. Verify the short circuit has been
resolved with an ohm-meter.
4. Reset the breaker/fuse or replace the
transformer.
Note: When replacing the
transformer, it is recommended to
replace with a model that utilizes a
resettable circuit breaker. A circuit
breaker makes solving wiring
problems easier.
1. Disconnect the Secondary of the 24
VAC transformer.
2. Use an ohm-meter to measure
between ~24 V HOT and COM; there
must be no short circuit.
Note: Some installations require
the secondary of the transformer
to be Earth Grounded. If this is
the case, verify that the Earth
Ground connection is valid and not
shared between multiple pieces of
equipment.
Configurable output - analog mode is
invalid:
0–10 V output is set to 10–100%, but 0 V is at
output terminals.
Output is in protection mode, a state the
analog portion of the configurable output
goes into when it detects a wiring problem.
The analog output is set to 0% regardless
of the command whenever a wiring fault is
detected.
Cause:
There is a power polarity mismatch between
the connected device and the configurable
output.
Correction:
Ensure polarities of ~24 V COM/CO-C match
and that the connected end device uses the
same polarity.
1. Measure the output and verify that it
matches the command.
2. Disconnect the connected device
and verify the commanded value is
present.
Configurable output - analog mode is
invalid:
0–10V output has an undesirable offset of up
to 1 V.
The Common Reference is incorrect.
Cause:
The CO-C terminal is not connected.
Correction:
Connect the CO-C terminal of the
configurable output to the common of the
connected end device.
1. Measure the output and verify that it
matches the command.
2. Disconnect the connected device
and verify the commanded value is
present.
