What are VAV Zone Controllers?
An i-Vu® Open Control System offers 2 VAV Zone Controllers, the VAV Zone Single Duct controller (#OPN-VAVB1)
and the VAV Zone Fan Terminal controller (#OPN-VAVB3), to control zone temperature using single duct or fan
powered terminals in a Variable Air Volume (VAV®) application. Although a VAV Zone Controller can be included in
a VVT system, this manual focuses mainly on its usage in VAV applications.
The VAV Zone Controller has a built-in actuator and maintains zone temperature by operating the terminal fan and
regulating the flow of conditioned air into the space. Buildings with diverse loading conditions can be supported by
controlling the local terminal's supplemental heat. The VAV Zone Controller provides dedicated control functions
for single duct, parallel fan box terminals and series fan box terminals with modulating heat, up to 2 stages of
ducted heat, or combination baseboard and ducted heat.
The following illustration shows the VAV Zone Controller in a typical i-Vu Open Control System.

NOTE
This document gives instructions for field-installation of a VAV Zone Controller in an i-Vu Open Control
System. However, VAV Zone Controllers are available factory-mounted to Carrier’s 35 single duct and 45 parallel
and series fan terminals. All terminals require an integrated duct temperature sensor.
VAV Zone Controllers 3

Introduction
Linkage
The i-Vu Open Control System uses linkage to exchange data between the zone terminals and their air source to
form a coordinated HVAC system. The system's air source controller and zone controllers are linked so that their
data exchange can be managed by one zone controller configured as the VAV Master.
A VAV Master can have a maximum of 63 slave zone controllers reporting to it. An MS/TP network is limited to a
maximum of 60 controllers, but a VAV Master can have controllers from other networks as slaves.
A linked VAV system can be as simple as a single MS/TP network with a VAV Master and slaves, or it can be as
complex as multiple MS/TP networks with VAV sub-masters and slaves on other networks. See the following
examples.
EXAMPLE #1
:A simple network. The VAV Master exchanges data between the slave controllers and the AHU
controller. The linked controllers on an MS/TP network must be sequentially addressed, and the VAV Master must
have the highest address.

support sub-masters.) The sub-masters exchange data between their slaves and the VAV Master, and the VAV
Master handles data exchange for the whole system.

Wiring the VAV Zone Controller for power
The VAV Zone Controller is powered by a Class 2 power source. Take appropriate isolation measures when
mounting it in a control panel where non-Class 2 circuits are present.
Carrier controllers can share a power supply as long as you:
• Maintain the same polarity
• Use the power supply only for Carrier Open controllers
To wire the controller for power
1 Remove power from the power supply.
2 Pull the screw terminal connector from the controller's power terminals labeled
Gnd
and
24 Vac
or
Hot
.
3 Connect the transformer wires to the screw terminal connector.
4 Apply power to the power supply.
5 Measure the voltage at the VAV Zone Controller’s power input terminals to verify that the voltage is within the
operating range of 21.6–26.4 Vac.
6 Connect a 4-inch (10.2 cm) wire from
Gnd
to the control panel.
7 Insert the screw terminal connector into the VAV Zone Controller's power terminals.
12 VAV Zone Controllers

Installation
8 Verify that the
Power
LED is on and the
Run
LED is blinking.
To address the VAV Zone Controller
You must give the VAV Zone Controller an address that is unique on the network. You can address the VAV Zone
Controller before or after you wire it for power.
1 If the VAV Zone Controller has been wired for power, pull the screw terminal connector from the controller's
power terminals labeled
Gnd
and
24 Vac
. The controller reads the address each time you apply power to it.
2 Using the rotary switches, set the controller's address. Set the
Tens
(
10's
) switch to the tens digit of the
address, and set the
Ones
(
1's
) switch to the ones digit.
EXAMPLE
If the controller’s address is 25, point the arrow on the
Tens
(
10's
) switch to 2 and the arrow on
the
Ones
(
1's
) switch to 5.

VAV Zone Controllers 13

Installation
Wiring the VAV Zone Controller to the MS/TP network
The VAV Zone Controller communicates using BACnet on an MS/TP network segment communications at 9600
bps, 19.2 kbps, 38.4 kbps, or 76.8 kbps.
Wire the controllers on an MS/TP network segment in a daisy-chain configuration.
Install a BT485 on the first and last controller on a network segment to add bias and prevent signal distortions
due to echoing.
See the MS/TP Networking and Wiring Installation Guide for more details.
Wiring specifications
Cable: 22 AWG or 24 AWG, low-capacitance, twisted, stranded, shielded copper wire
Maximum length: 2000 feet (610 meters)
To wire the controller to the network
1 Pull the screw terminal connector from the controller's power terminals labeled
Gnd
and
24 Vac
or
Hot
.
2 Check the communications wiring for shorts and grounds.
3 Connect the communications wiring to the BACnet port’s screw terminals labeled
Net +
,
Net -
, and
Shield
.
NOTE
Use the same polarity throughout the network segment.
4 Verify that the
MSTP
jumper is set to
MSTP
.
5 Set DIP switches 1 and 2 to the appropriate baud rate. See the MSTP baud diagram on the VAV Zone
Controller. The default baud rate is 76.8 kbps.
NOTE
Use the same baud rate for all controllers on the network segment.

Installation
6 Insert the power screw terminal connector into the VAV Zone Controller's power terminals.
7 Verify communication with the network by viewing a module status report.
Wiring sensors to inputs
You can wire the following sensors to the VAV Zone Controller's inputs:
•Space temperature sensor
•Alternate space temperature sensor (page 18)
•Supply Air Temperature sensor (page 18)
•CO2sensor (page 19)
•Relative Humidity sensor (page 21)
•Remote occupancy contact sensor (page 22)
NOTE
This document gives instructions for wiring the sensors to the VAV Zone Controller. For mounting and wiring
the sensors, see the Carrier Sensors Installation Guide.
Disconnect electrical power to the VAV Zone Controller before wiring it. Failure to follow this warning could
cause electrical shock, personal injury, or damage to the controller.
•Do not run sensor or relay wires in the same conduit or raceway with Class 1 AC or DC service wiring.
•Do not abrade, cut, or nick the outer jacket of the cable.
•Do not pull or draw cable with a force that may harm the physical or electrical properties.
•Avoid splices in any control wiring.
