PCV1617 and PCV1632 VAV Box Controllers
Installation instructions
Applications
The PCV1617 and PCV1632 are programmable digital controllers designed for VAV box applications
that communicate through the BACnet® 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 PCV controllers connect easily to either the networked or to the non-
communicating sensor for zone air temperature sensing.
Communications Protocol
The PC family controllers and network sensors communicate using the standard BACnet protocol,
based on the ANSI/ASHRAE 135-2008. The BACnet protocol is a standard for ANSI, ASHRAE, and the
International Standards Organization (ISO) for building controls.
PCV field controllers are BTL-listed as BACnet Application Specific Controllers (B-ASCs).

Mounting
Observe these guidelines when mounting a 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 PCV
electronics. Mount the PCV vertically above the damper shaft to allow any shaft condensation
to fall away from the PCV. Additional measures may be required in some installations.
• Ensure the mounting surface can support the PCV and any user-supplied enclosure.
• Mount the PCV on a hard, even surface whenever possible.
• Use shims or washers to mount the PCV securely and evenly on the mounting surface.
• Mount the PCV in an area free of corrosive vapors that matches the ambient conditions specified
in the Technical specifications section.
• Provide sufficient space around the 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 PCV in areas where electromagnetic emissions from other devices or wiring
can interfere with controller communication.
• When using the PCV1617 or PCV1632 to replace an existing controller, plug the unused open hole
from the original controller mounting, if possible.
• Avoid mounting the PCV on surfaces with excessive vibration.
On panel or enclosure mount applications, observe these additional guidelines:
• Do not install the PCV in an airtight enclosure.
• Mount the PCV so that the enclosure walls do not obstruct cover removal or ventilation through
the controller.
• Mount the PCV so that the power transformer and other devices do not radiate excessive heat to
the controller.
PCV1617 and PCV1632 VAV Box Controllers Installation instructions2

To mount a PCV1617 or PCV1632 controller:
1. Set all the switches on the PCV controller to their known settings.
2. Place the PCV controller in the proper mounting position on the damper shaft so that the
wiring connections are easily accessible. Make sure the PCV controller base is parallel to the
VAV box (perpendicular to the damper shaft). If needed, use a spacer to offset tipping of the
PCV controller caused by the shaft bushings.
Note: Use the alignment marks to center the captive spacer to ensure sufficient 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 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 PCV controller at the full-open position, the 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).
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 PCV controller and the other ends of the tubing to the pressure transducer in the
VAV box application.
Note: The 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
3PCV1617 and PCV1632 VAV Box Controllers Installation instructions

barbed fitting on the 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 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.
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.

Warning
Risk of Electric Shock:
Disconnect or isolate all power supplies before making electrical connections. More than one
disconnection or isolation may be required to completely de-energize equipment. Contact with
components carrying hazardous voltage can cause electric shock and may result in severe personal
injury or death.
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.
PCV terminals and bus ports
See Figure 2 for input and output terminal and bus port locations on the PCV1617 and PCV1632
controllers. Observe the following guidelines when wiring a PCV controller.
PCV1617 and PCV1632 VAV Box Controllers Installation instructions6

Input and Output terminals
The input spade terminals are located on the side of the 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
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 PCV and other 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 terminal blocks
Wire the SA Bus terminal blocks on the 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
the following diagram. . See Table 5 for more information.
7PCV1617 and PCV1632 VAV Box Controllers Installation instructions

Figure 4: SA bus terminal block wiring
Modular port
The modular (TSTAT) port on the face of the 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 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 5.
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 5: Pin number assignments for the
modular port on PCV1617 and 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 PCV controller.
PCV1617 and PCV1632 VAV Box Controllers Installation instructions8

Wire the 24 VAC supply power wires from the transformer to the HOT and COM terminals on the
spade terminals as shown in Figure 6. See Table 5 for more information.
Figure 6: 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 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 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 7: 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 on -1 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.

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 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 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 8 to estimate the maximum cable length relative to the wire size and the load current (in
mA) when wiring inputs and outputs.
