Installation Instructions
Part No. 24-10143-489, Rev. CFX-PCV1617, FX-PCV1632
Issued July 2017
Refer to the QuickLIT website for the most up-to-date version of this document.
Applications
The FX-PCV1617 and FX-PCV1632 are programmable
digital controllers designed for VAV box applications that
communicate by using the BACnet®
Master-Slave/Token-Passing (MS/TP) protocol. The
controllers feature an integral digital pressure sensor, a
damper actuator, and a 32-bit microprocessor. The
controllers' small package size facilitates quick field
installation and efficient use of space without
compromising high-tech control performance. The
FX-PCV controllers connect easily to either the networked
or to the non-communicating sensor for zone air
temperature sensing.
Switchable Communications
Protocols
By default, the FX-PC Family Controllers and network
sensors communicate using either the standard BACnet
protocol based on the ANSI/ASHRAE 135-2004, or the
BACnet/IP protocol.
The BACnet protocol is a standard for ANSI, ASHRAE,
and the International Standards Organization (ISO) for
building controls.
FX-PCG, FX-PCX, and FX-PCV Controllers are BTL-listed
as BACnet Application Specific Controllers (B-ASCs).
FX-PCA Field Controllers and the VMA1930 Field
Controller are BTL-listed as BACnet Advanced Application
Controllers (B-AACs). The NS Series Sensors are
BTL-listed as BACnet Smart Sensors (B-SSs).
Release 10.1 and later of the FX-PCT can be used to
switch the Field Bus communications protocol in
supported FX-PC Controllers to be either the standard
BACnet Master-Slave/Token-Passing (MS/TP) or the N2
protocol. All new controllers either use BACnet MS/TP
as the default communications protocol, or BACnet/IP.
Switchable communications protocols in the MS/TP
models provide a cost-effective upgrade and
modernization path for customers with existing N2
controllers. The Modernization Guide for Legacy N2
Controllers (LIT-12012045) and the controller-specific
documentation provide installation and commissioning
support and include tips for efficient and safe
replacement. Refer to the N2 Compatibility Options
chapter of the Controller Tool Help (LIT-12011147) for
information about mapping N2 Objects in controllers with
switchable communications protocols.
The N2-capable FX-PC Controllers can be used as
functional replacements for legacy N2 controllers. The
N2-capable FX-PC Controllers:
• have the I/O quantities and characteristics of the
FX-PC family controllers
• must be programmed with FX-PCT, which has
programming capabilities that are similar (but not
identical) to HVACPro, GX9100, GPL, and other
legacy tools
• support SA Bus devices
•support FX-WRZ wireless sensors from the controller
using the FX-WRZ7860 receiver when configured for
BACnet MS/TP communication
The N2-capable FX-PC controllers:
• do not support Zone Bus (for example, TMZ sensors
and M100 actuators)
• do not support passthrough in the commissioning
mode
•do not support remote downloading or commissioning
using BACnet routing
• do not support wireless connection to the N2 bus

Mounting
Observe these guidelines when mounting an FX-PCV:
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
FX-PCV electronics. Mount the FX-PCV
vertically above the damper shaft to allow
any shaft condensation to fall away from
the FX-PCV. Additional measures may be
required in some installations.
•Ensure the mounting surface can support the FX-PCV
and any user-supplied enclosure.
•Mount the FX-PCV on a hard, even surface whenever
possible.
• Use shims or washers to mount the FX-PCV securely
and evenly on the mounting surface.
•Mount the FX-PCV in an area free of corrosive vapors
that matches the ambient conditions specified in the
Technical Specifications section.
•Provide sufficient space around the FX-PCV 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 FX-PCV in areas where
electromagnetic emissions from other devices or
wiring can interfere with controller communication.
• When using the FX-PCV1617 or FX-PCV1632 to
replace an existing controller, plug the unused open
hole from the original FX-PCV mounting, if possible.
• Avoid mounting the FX-PCV on surfaces with
excessive vibration.
2FX-PCV1617 and FX-PCV1632 VAV Box Controllers Installation Instructions

On panel or enclosure mount applications, observe these
additional guidelines:
• Do not install the FX-PCV in an airtight enclosure.
• Mount the FX-PCV so that the enclosure walls do not
obstruct cover removal or ventilation through the
controller.
•Mount the FX-PCV so that the power transformer and
other devices do not radiate excessive heat to the
controller.
To mount an FX-PCV1617 or FX-PCV1632 controller:
1. Set all the switches on the FX-PCV controller to their
known settings.
2. Place the FX-PCV controller in the proper mounting
position on the damper shaft so that the wiring
connections are easily accessible. Make sure the
FX-PCV controller base is parallel to the VAV box
(perpendicular to the damper shaft). If needed, use
a spacer to offset tipping of the FX-PCV controller
caused by the shaft bushings.
Note: Use the alignment marks to center the captive
spacer to ensure sufficient FX-PCV
movement in either direction.
3. Secure the self-drilling No. 10 screw through the
captive spacer with a power screwdriver and 100
mm (4 in.) 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 3.5 mm (9/64
in.) drill bit. Insert the mounting screw and tighten
against the spacer.
Important: Do not overtighten the screw, or the
threads may strip. If you are mounting
the controller to a 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 (Figure 1).
Figure 1: 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 FX-PCV 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, hard stops must be provided
at both full-closed and full-open damper positions.
By installing the FX-PCV controller at the full-open
position, the FX-PCV controller provides the open
stop for 45° and 60° boxes. The closed damper seal
provides the full-closed stop.
8. 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 11 N·m , ±.5 N-m (100 lb·in, ±5
lb·in).
3FX-PCV1617 and FX-PCV1632 VAV Box Controllers Installation Instructions

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
FX-PCV controller and the other ends of the tubing
to the pressure transducer in the VAV box
application.
Note: The FX-PCV uses a digital non-flow pressure
sensor with bidirectional flow operation, which
allows the high- and low-pressure DP tube
connections to be made to either barbed
fitting on the FX-PCV controller. There is no
need to make a specific high- or low-side
connection when attaching the tubing to the
barbed fittings on the FX-PCV.
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.
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.

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.
FX-PCV Terminals and Bus Ports
See Figure 2 for input and output terminal and bus port
locations on the FX-PCV1617 and FX-PCV1632
controllers. Observe the following guidelines when wiring
an FX-PCV controller.
Input and Output Terminals
The input spade terminals are located on the side of the
FX-PCV near the FC Bus terminal block. The output
spade terminals are located on the opposite side of the
controller near the power supply spade terminals. See
Table 2 for more information.
FC Bus Terminal Block (Or N2 Protocol As
Required)
The FC Bus terminal block is a blue, removable,
4-terminal plug that fits into a board-mounted jack.
Wire the removable FC Bus terminal block plugs on the
FX-PCV and other FX-PC controllers in a daisy-chain
configuration using 3-wire twisted, shielded cable as
shown in Figure 3. See Table 5 for more information.
Figure 3: FC Bus Terminal Block Wiring
Note: The Shield terminal (SHLD) on the FC Bus
terminal block is isolated and can be used to
connect the cable shields on the bus (Figure 3).
SA Bus Spade Lugs
Wire the SA Bus spade lugs on the FX-PCV and other
SA Bus devices, such as a communicating NS-family
room sensor, in a daisy-chain configuration using 4-wire
twisted, shielded cable as shown in Figure 4. See Table
5for more information.
Figure 4: SA Bus Spade Lug Wiring
7FX-PCV1617 and FX-PCV1632 VAV Box Controllers Installation Instructions

Figure 5: SA Bus Terminal Block Wiring
Modular Port
The modular (TSTAT) port on the face of the FX-PCV
(Figure 2) is an RJ-45, 8-position modular jack used to
easily connect one TE-730 series analog
(non-communicating) sensor to the FX-PCV. The modular
TSTAT port provides 15 VDC, SA Bus communications,
and analog signals for zone temperature, zone setpoint,
and temporary zone occupancy override.
Note: On the TE-730 Series sensors, you can activate
the occupancy override functionality by using a
pushbutton to momentarily short the zone
temperature AI.
The TSTAT pin assignment is shown in Figure 6.
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.
Figure 6: Pin Number Assignments for the Modular
Port on FX-PCV1617 and FX-PCV1632 Controllers
Supply Power Terminal Block
The 24 VAC supply power terminal block is a gray,
removable, 2-terminal plug that fits into a board-mounted
jack on the upper left of the FX-PCV controller.
Wire the 24 VAC supply power wires from the transformer
to the HOT and COM terminals on the spade terminals
as shown in Figure 7. See Table 5 for more information.
Figure 7: 24 VAC Supply Power Spade Terminal
Wiring
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
FX-PCV 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 FX-PCV does
not require an earth ground connection.
However, when grounding the secondary
of the 24 VAC transformer is required, only
one connection to ground should be made
near the transformer. See the following
figure.
Figure 8: Transformer Grounding
8FX-PCV1617 and FX-PCV1632 VAV Box Controllers Installation Instructions

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 on -1 FX-PCV models. 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.
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.a. des FX-PCV 16xx-1 modèles.
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 FX-PCV1617 or FX-PCV1632 controller:
1. Terminate wiring according the appropriate figure in
Termination Diagrams.
2. Wire network sensors and other devices to the
FX-PCV 's SA Bus.
3. Wire the FC Bus in a daisy chain.
4. Ensure that the FX-PCV ’s device address DIP
switches are set to the appropriate device address.
See Setting the Device Address. Also, activate the
end-of-line (EOL) switch if necessary.
5. Connect the FX-PCV controller to 24 VAC, Class 2
power.
FX-PCV Terminal Functions, Ratings,
Requirements, and Wiring Guidelines
Input and Output Wiring Guidelines
Table 2 provides information about the functions, ratings,
and requirements for the FX-PCV input and output
terminals, and Table 3 provides guidelines for wire sizes
and cable lengths.
In addition to the wiring guidelines in Table 2, observe
these guidelines when wiring FX-PCV inputs and outputs:
• Run all low-voltage wiring and cables separate from
high-voltage wiring.
• All input and output cables, regardless of wire size or
number of wires, should consist of twisted, insulated,
and stranded copper wires.
• Shielded cable is recommended for input and output
cables that are exposed to high electromagnetic or
radio frequency noise.
• Cable runs of less than 30 m (100 ft) typically do not
require an offset in the input/output software setup.
Cable runs over 30 m (100 ft) may require an offset
in the input/output software setup.
Maximum Cable Length versus Load Current
Use Figure 9 to estimate the maximum cable length
relative to the wire size and the load current (in mA) when
wiring inputs and outputs.
FC and SA Bus and Supply Power Wiring
Guidelines
Table 5 provides information about terminal block
functions, ratings, and requirements.
Table 5 also provides wire size, cable type, and cable
length guidelines for wiring the FX-PCV communication
buses and supply power.
In addition to the guidelines in Table 5, observe these
guidelines when wiring the SA/FC Buses and supply
power:
• Run all low-voltage wiring and cables separate from
high-voltage wiring.
• All FC and SA Bus cables, regardless of wire size,
should be twisted, insulated, stranded copper wire.
• Shielded cable is strongly recommended for all FC

MS/TP (SA or FC) Buses. Before operating and FX-PC
controllers connect easily to the non-communicating
sensor for zone air controllers on a bus, you must set a
valid and unique device address for each controller on
the bus.
You set an FX-PC controller’s device address by setting
the positions of the switches on the Device Address DIP
switch block at the top of the controller. Device addresses
4 through 127 are the valid addresses for these
controllers.
The DIP switch block (Figure 10) has eight switches
numbered 128, 64, 32, 16, 8, 4, 2, and 1. Switches 64
through 1 are device address switches. Switch 128 is a
mode switch that enables an FX-PC controller to operate
on an FX-ZFR Series Wireless Field Bus. Switch 128
must be set to OFF for all hard-wired SA and FC Bus
applications. Set Switch 128 to ON for wireless FC Bus
applications only.
Figure 10: Device Address Switches Set to 21
Note: FX-PC Series controllers ship with Switch 128
ON and the remaining address switches OFF.
This renders the controllers wired slave devices,
which do not interfere on MS/TP Buses and do
not interfere with bus operation. Set a valid and
unique device address on the FX-PC controller
before applying power to the controller on the bus.
To set the device addresses on an FX-PC Series
Controller:
1. Set all of the switches on the FX-PC controller’s
device address DIP switch block (128 through 1) to
OFF.
2. Set one or more of the seven address switches (64
through 1) to ON, so that the sum of the switch
numbers set to ON equals the intended device
address. See Table 6 and Table 7 for valid FX-PC
controller addresses.
Set the highest number switch that is less than or
equal to the intended device address to ON. Then
continue setting lower numbered switches until the
total equals the intended address. For example, if the
intended device address is 21, set Switch 16 to ON
first, then set Switch 4 ON, followed by Switch 1
(16+4+1=21). See Figure 10.
3. Set Switch 128 to ON only for controllers on an
FX-ZFR Series Wireless Field Bus application. For
all hard-wired SA and FC Bus applications, ensure
that Switch 128 is set to OFF.
Note: Do not connect a wirelessly enabled FX-PC
controller to a wired FC Bus.
4. Set a unique and sequential device address for each
of the FX-PC controllers connected on the SA or FC
Bus, starting with device address 4.
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 FX-PC
16FX-PCV1617 and FX-PCV1632 VAV Box Controllers Installation Instructions

controllers do not need to be physically connected
on the bus in their numerical device address order.
5. Write each FX-PC controller’s device address on the
white label below the DIP switch block on the
controller’s cover.
Table 6 shows and describe the valid FC Bus and SA
Bus device addresses for Johnson Controls MS/TP
communications bus applications.

wired field bus, the field bus is
rendered inoperable until the controller
is disconnected or Switch 128 is set
to OFF.
Setting the N2 Controller Address to be
Greater than 127
N2-configured controllers support the full range of
possible N2 device addresses provided by the N2 protocol
standard (1-255). However, these controllers require
special configuration for addresses above 127. Use the
following instructions for controllers greater than 127.
Notes:
• Before you perform this procedure, make sure that
your controller has been converted from BACnet to
N2 protocol first. Refer to the Modernization Guide
for Legacy N2 Controllers (LIT-12012045) for more
information.
• This special configuration is required because
controller addresses above 127 were originally
intended for use with the Wireless Field Bus system.
1. Disconnect the 24 VAC supply from the controller.
2. Remove the FC Bus connector from the controller.
3. Set the address switch set to the desired N2 address.
4. Set the address switch segment labeled 128 to OFF.
5. Reconnect the 24 VAC supply to the controller.
6. Download the firmware and controller application
file. The download process asks to confirm switching
the communication protocol to N2.
7. Click OK.
8. After the download is finished, disconnect the 24
VAC supply to the controller.
9. Set the address switch segment labeled 128 to ON.
10. Reattach the FC Bus connector to the controller.
11. Reconnect the 24 VAC supply to the controller.
Setting the EOL Switch
Each FX-PC controller has an EOL switch, which when
set to ON (up), sets the FX-PC controller as a terminating
device on the bus. See Figure 11 for the EOL switch
location on the FX-PC . The default EOL switch position
is OFF (down). The amber EOL LED illuminates to show
that the EOL is active.
Figure 11: EOL Switch Positions
17FX-PCV1617 and FX-PCV1632 VAV Box Controllers Installation Instructions

To set the EOL switch on an FX-PC controller:
1. Determine the physical location of the FX-PC
controller on the SA or FC Bus.
2. Determine if the FX-PC controller must be set as a
terminating device on the bus.
Note: The EOL termination rules for SA Buses and
FC Buses are different.
3. If the FX-PC is a terminating device on the FC Bus,
set the EOL switch to ON. If the field controller is not
a terminating device on the bus, set the EOL switch
to OFF.
Note: When the EOL switch is set to ON, the LED
light on the face of the controller is illuminated.
Commissioning
Use the following procedure to commission the
FX-PCV1617 or FX-PCV1632 controller:
1. Download the control application to the FX-PCV
controller using the Programming and Commissioning
Tool (PCT). Refer to the Controller Tool Help
(LIT-12011147).
2. Commission the VAV Box. Refer to the Controller
Tool Help (LIT-12011147).
3. Perform airflow balancing on the VAV box. Refer to
the VAV Balancing Tool and Network Sensors
Technical Bulletin (LIT-12011087).
4. Perform commissioning checkout procedures. Refer
to the Controller Tool Help (LIT-12011147).
The FX-PCT connects to the FX-PCV through a laptop
computer using different connection options: the
Bluetooth®Commissioning Converter, the Wireless ZFR
USB Dongle, or the wired BACnet Ethernet to MS/TP
Router can be used when using the BACnet MS/TP
protocol. When the controller is configured to use the N2
protocol, you must use the Commissioning Converter at
the SA bus. Wireless connections are not supported in
N2 mode. These connection options require additional
hardware listed in Table 10.
Repair Information
If the FX-PCV1617 or FX-PCV1632 controller fails to
operate within its specifications, replace the unit. For a
replacement unit, contact the nearest Johnson Controls
representative.
Troubleshooting
Table 9 provides LED status indicator information for troubleshooting the FX-PCV1617 and FX-PCV1632 controllers.
The following table provides some additional troubleshooting information for possible problems.
Note: If you experience short circuits in the 24 VAC power supply that cause protective devices such as breakers
or fuses to trip, make sure that the power connections on the FX-PCV are not reversed. The most common
cause of this problem is when the 24 VAC power supply on the FX-PCV is reversed but it is not reversed
on a connected secondary device. Improper wiring of this power terminal may cause a short circuit across
the 24 VAC power supply.
