Introduction
Read this manual thoroughly before operating or servicing
this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
required.Your personal safety and the proper operation of
this machine depend upon the strict observance of these
precautions.
Important Environmental Concerns
Scientific research has shown that certain man-made
chemicals can affect the earth’s naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are refrigerants
that contain Chlorine, Fluorine and Carbon (CFCs) and
those containing Hydrogen, Chlorine, Fluorine and
Carbon (HCFCs). Not all refrigerants containing these
compounds have the same potential impact to the
environment.Trane advocates the responsible handling of
all refrigerants-including industry replacements for CFCs
such as HCFCs and HFCs.
Important Responsible Refrigerant Practices
Trane believes that responsible refrigerant practices are
important to the environment, our customers, and the air
conditioning industry. All technicians who handle
refrigerants must be certified.The Federal Clean Air Act
(Section 608) sets forth the requirements for handling,
reclaiming, recovering and recycling of certain
refrigerants and the equipment that is used in these
service procedures. In addition, some states or
municipalities may have additional requirements that
must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.

General Information
This section provides general information about the wireless Comm interface (WCI).
Product Description
TheTrane® Wireless Comm Interface (WCI) enables wireless communication between system
controls, unit controls, and wireless sensors for the new generation ofTrane control products.The
WCI replaces the need for communication wire in all system applications.
Types of Devices Supported by the WCI
• Tracer™ SC system controller
• Tracer™ UC210 programmable controller
• Tracer™ UC400 programmable controller
• Tracer™ UC600 programmable controller
• BCI-I: BACnet Communications Interface for IntelliPak™ systems
• BCI-R: BACnet Communications Interface for ReliaTel™ systems
• Tracer™TU
• Wireless zone sensors
Quantity of WCIs per Network
EachTrane wireless network can have a total of 31WCIs (30 member WCIs plus 1 coordinatorWCI).
Each network requires one WCI to function as network coordinator.
Quantity of Networks per Tracer SC
ATracer SC can support up to 8 wireless networks.
Notes:
• The number of WCIs that can be installed at a site is determined by the applicable
Tracer SC license, which specifies the total number of controllers.
• For information about installing aWCI on aTracer SC, see “Mounting andWiring theWCI,”
p. 13 and Figure 6, p. 15.
Automatic Network Formation
When a WCI is connected to aTracer SC, it is auto-assigned as the coordinator.To enable the
coordinator,Tracer SC must be configured for wireless communication.The coordinator WCI
opens the network to allow allWCIs having matching addresses to automatically join the network.
If noTracer SC is present, a centrally located WCI connected to a programmable controller or a BCI
must be designated to act as the coordinator.You can manually set the coordinatorWCI so all WCIs
having matching addresses automatically join the network.
Note: For additional information, see “Establishing the Network,” p. 18.
Wireless Zone Sensors
TheWCI also communicates withTrane wireless zone sensors, eliminating the need for standalone
receivers.
Wired Zone Sensors
Systems using Wireless Comm can also use wired zone sensors.
Network Security
The WCI uses standard ZigBee™ Building Automation security practices by the use of AES128
encryption, keys, and device authentication.

Layer (PHY) Specifications for Low Rate Wireless Personal Area Networks (LR-WPANs)
(a)Range values are estimated transmission distances for satisfactory operation. Actual distance is job specific and must be determined during site eval-
uation. Placement of the WCI is critical to proper system operation. In most general office space installations, distance is not the limiting factor for
proper signal quality. Signal quality is more greatly affected by walls, barriers, and general clutter. Note that sheetrock walls and ceiling tiles offer little
restriction to the propagation of the radio signal throughout the building as opposed to concrete or metal barriers. More details information, including
wiring schematics, are available at http://www.trane.com.

Location Considerations
To provide the best signal strength between associated wireless devices and to reduce the number
of WCIs needed for an application, mount WCIs in direct, unobstructed, line-of-sight paths. Locate
WCIs so that the number of metal and concrete barriers between pairs of devices is minimal. In
general, sheetrock walls and ceiling tiles are not of concern.
For more detailed information aboutWCI placement, see theWireless Comm Network Design Best
Practices Guide (BAS-SVX55).
The WCI produces very low levels of electromagnetic (RF) energy. To avoid exposure, keep the WCI a minimum of 8
in. (20 cm) from your body.
Maximum Wire Length
The maximum wire length between the WCI and its power source is 656 ft (200 m).
Note: The connector that comes with the WCI is one meter in length.
Installation Locations
Unit controller
For a unit controller installation, the most typical WCI mounting location is on the sheet metal
enclosure of the unit controller or HVAC equipment housing.
Coordinator Location
For optimum network performance and reliability, the coordinator WCI should be centrally located
within the network. See theWireless Comm Network Design Best Practices Guide (BAS-SVX55) for
more detail.
Repeaters overcome out-of-radio-range issues
A WCI can be installed to function as a repeater to bridge the signal between a WCI that is out of
the radio range of the other WCIs (see “Repeater Applications,” p. 17). When choosing a location
for a repeater WCI, consider the availability of a 24 Vac/Vdc power source to meet its power
requirement.
Note: A repeater extends comm link radio communications only. It cannot be used to extend
wireless zone sensor communications.
Coordinator and repeater placement recommendations on sites without VAV
boxes
The recommended mounting location for RTU installations is in the return plenum, above the roof
penetration.This location provides the best overall sensor and communication link quality, and
makes access to the WCI easier than below the roof deck for improved serviceability.
In RTU/VAV systems, there is adequate network density minimizing the need for repeaters.
However, the increased distance between devices on single zone rooftops means that repeaters
will be required in many of these installations. Unlike VAV boxes, which may be within line of site,
RTUs have greater obstructions between devices, such as steel roof decks and return ducts.
CAUTION
Avoid exposure to electromagnetic energy!
The WCI produces very low levels of electromagnetic energy. To avoid exposure, keep the WCI
a minimum of 8 in. (20 cm) from your body.
Risque d’exposition à l’énergie électromagnétique!
L’interface de communication (WCI) sans fil produit de l'énergie électromagnétique de très bas
niveau. Afin d'empêcher toute exposition, maintenez-la à au moins 20 cm (8 pouces) de votre
corps.

10 BAS-SVX40B-EN
Location Considerations
Consequently, the design range between these devices is shorter. Based on our tests, we
recommend a design range of 100 feet.

BAS-SVX40B-EN 11
WCI Addressing
This section describes theWCI addressing scheme and procedure. WCIs can be ordered either pre-
addressed or without addresses. Verify pre-addressed WCI prior to installation.
Setting Network Communication Addressing
Important: Addresses must be set on WCIs before applying power to them.
Follow this procedure to set the WCI address for network communication. Figure 1 illustrates the
addressing scheme used for WCIs.The illustration shows four networks and twoTracer SCs, with
eachTracer SC communicating on two networks. See Table 1, p. 12 for address settings.
1. Set the left (GRP) rotary address switch for each WCI that is in the sameTracer SC group to an
identical number. (ATracer SC group refers to all of the networks that communicate with the
sameTracer SC.)
2. Set the right (NET) rotary address switch for each WCI that is to be on the same network to an
identical number. If there are multiple networks in aTracer SC group, each network in that group
must have a unique number.
Note: The NET address (ranging from1-8)must match the wireless link onTracer SC.
Figure 1. WCI addressing example
Note: The Wireless Comm Network Design Best Practices Guide (BAS-SVX55) provides an
example of network addressing from a floor plan perspective.

WCI Addressing
*Must match the wireless link network number. (See “Tracer SC Addressing” in the Wireless Comm Network Design Best Prac-
tices Guide (BAS-SVX55.)
Setting Wireless Zone Sensor Receiver Addressing
AWCI that is installed on a unit controller as a wireless communication interface can also function
as a zone sensor receiver.To set up this function, follow this procedure:
WARNING
Hazardous voltage!
Disconnect all electric power, including remote disconnects before servicing. Follow proper
lockout/tagout procedures to ensure that power cannot be inadvertently energized. Failure to
disconnect power before servicing could result in death or serious injury.
1. Make sure that AC power is disconnected from the unit controller that the WCI is installed on.
2. Choose unit controller and wireless zone sensor addresses so that no two wireless zone sensors
sharing the same address are within radio range of each other. (Addresses above 127 may be
used for Wireless Comm systems. See the Wireless Comm Network Design Best Practices
Guide (BAS-SVX55) for more information.)
3. Set the address on the wireless zone sensor to match the rotary address setting on the unit
controller (see Figure 2).
Note: The numbers on the WCI rotary address switches are oriented differently from those on
the unit controllers, as the illustration indicates.

Mounting and Wiring the WCI
5. Route the wires from the WCI through either:
a. The opening in the back plate (Figure 5, a).
b. The bottom exit port (Figure 5, b).
Figure 5. Routing the wires through the WCI backplate (a) or bottom exit port (b)
6. Connect the wiring harness according to the illustration that is appropriate for your application:
Note: Wiring between a WCI and a controller cannot exceed 656 ft (200 m). If the wiring
harness does not provide enough length, use 18 AWG (24 pF/ft max.) communication
wire (Trane purple wire, which is shielded).To extend both the comm link and the power,
use two pieces orTrane purple wire (4 conductors, 2 shields). Each shield needs to be
grounded at one spot.The shield should be grounded at the UC, the BCI, or the PM014.
If you power theWCI remotely, then you only need to run one piece ofTrane purple wire
(2 conductors, 1 shield) for the comm link.Trane recommends that you ground the
shield at the UC, the BCI, or the PM014.
Note:
•To wire the WCI to aTracer SC, see Figure 6, p. 15.
•To wire the WCI to a UC210, UC400, or a UC600, see Figure 8, p. 16.
•To wire the WCI to a BCI-I, see Figure 9, p. 16.
•To wire the WCI to a BCI-R, see Figure 10, p. 16.
Note: For detailed information, refer to the BACnet MS/TP Wiring and Link Performance Best
Practices andTroubleshooting Guide (BAS-SVX51)
7. Restore power to the controller.
Important: The WCI must be wired to the controller prior to power up in order to establish
network communication. If you cannot apply power to theWCI and the controller
at the same time, apply power to theWCI first. However, if you use a remote power
source to power the WCI, apply power to the WCI before applying power to the
unit controller.
8. The network is ready to be formed. Refer to “Establishing the Network,” p. 18.

5. Remove the blue (IMC+) and gray (IMC-) wires from the wiring harness.
6. Connect the red (24Vdc/Vac) wire and black (ground) wire through the opening in the backplate
(Figure 5a) or the bottom exit port (Figure 5b) to a 24 V power source (AC or DC).

7. Apply power to the WCI.
Changing a WCI from Device Association to Repeater
If the WCI communication wire was previously connected to a unit controller, return the WCI to its
default configuration as follows:
1. Set its rotary address switch to 0,0 (the WCI must be powered).
2. Observe its LEDs blink On briefly (<1 second). (It takes about 10 seconds for the blink to occur.)
3. Reset its rotary address switches to the correct network address.
You are now ready to add the repeater to an existing network (refer to “Adding AdditionalWCIs
to an Existing Network,” p. 23) or to proceed with establishing a new network (refer to
“Establishing the Network,” p. 18).
Note: When the repeater is added, its DIAG LED blinks constantly. This behavior is normal.

Establishing the Network
When all aspects of hardware installation are complete, you are ready to power up the system and
establish the network. Before you perform these tasks, ensure that all work described in the “WCI
Addressing,” p. 11 and “Mounting and Wiring the WCI,” p. 13 sections are complete. If you cannot
power up all devices at the same time, then power them up in the following order: (1)all WCIs, (2)
all Unit Controllers (UC210, UC400, UC600, BCI-I, BCI-R), (3) theTracer SC , (4) wireless zone
sensors, if present.
WCI LEDs and Buttons
Before establishing a network, you should be familiar with the layout of the WCI board, the
behavior of its LEDs, and the function of its buttons.The WCI board contains two buttons and
several LEDs.The LEDs relevant to network formation are shown in Figure 12.

The green NWK LED:
• Illuminates on every WCI that has joined the
network.
• Flashes for 10 seconds every 2.5 minutes if the
WCI is not a member of the network.
The yellow CRD LED
illuminates on the
coordinator WCI.
The START button:
• On a network without a
Tracer SC, designates a
WCI as the network
coordinator and opens the
network for joining.
• Removes a member WCI
from the network (see
“Removing a WCI from a
Network,” p. 24).
• Disbands the network (see
“Disbanding a Network,”
p. 24).
The green SNSR LED:
• Illuminates on a WCI that functions as a zone sensor
r
and is associated with a sensor.
• Flashes slowly if not associated with a sensor.
• Flashes quickly if associated with a sensor and
the sensor button is pushed.
OPEN NET LED
• All member WCIs and
the coordinator WCI
illuminate this LED
when the network is
opened from Tracer TU
or the coordinator WCI.
• If the network is
opened from a member
WCI (Open button),
only the member WCI
illuminates its OPEN
NET LED. Any WCI
withinrangeofthisWCI
can join the network.
The OPEN NET button:
• On coordinator WCI, opens
network for 1 hour.
• On coordinator WCI, extends
time that network is open for
additional hour.
• On member WCI, opens that
WCI for 10 minutes.
• Closes open network when
pressed on the coordinator
WCI.
• Closes just the member WCI
when pressed on an open
member WCI.
Note: There are two very small LEDs at the bottom of theWCI board next to
the sensor radio chip (labeled LED1 and LED2).The red LED flashes
during a channel scan.The flashing occurs for about 1 minute after the
controller is powered up. It is always lighted when the associated
device is installed on aTracer SC.

Establishing the Network
On power-up, the WCI goes through a check list and updates LED activity according to the type of
device associated with the WCI and the status of the WCI in the network.The LED flash patterns
vary depending on current conditions. LED behavior is described in Table 2.

One of the following causes:
• WCI lost MAC address on radios or WCI lost
ability to communicate with radio.
• WCI could be a repeater.
• WCI lost IMC link to the UC/BCI/PM014
Corrective Action: Cycle power to restore
communications with unit controller. MAC
address can be checked on TU >Wireless >

Establishing the Network
Three Ways to Establish a Wireless Network
A wireless network can established:
• After aTracer SC has been installed.
• Prior toTracer SC installation.
• On a network that will not have aTracer SC installed on it.
Establishing the Network After Tracer SC Installation
If aTracer SC is installed prior to establishing the wireless network, the WCI that is installed on a
Tracer SC automatically becomes the network coordinator after power is applied to theTracer SC.
If multiple WCIs are installed on aTracer SC, each WCI forms an independent network for which
it is the coordinator.
Follow this procedure:
1. Observe the yellow CRD LED on the WCI illuminate to identify the WCI wired to theTracer SC
as the network coordinator (see Figure 12, p. 18).
2. Observe the yellow OPEN_NET LED illuminate on the coordinatorWCI.This LED remains lit for
1 hour, indicating that the network is open to allow WCIs with matching addresses to join the
network for that duration. After each WCI joins, the 1 hour timer starts over.
Note: If the network closes because the timer has expired, you can open the network for an
additional hour by pressing the OPEN_NET button on the network coordinator WCI.To
extend time on a network that has not yet closed, press the OPEN_NET button on the
coordinator to close the network, then press it again to open the network for an
additional hour. As an alternative, you can use TracerTU to open the network.
3. Observe the green NWK LED illuminate:
•On the coordinator WCI, indicating that it has joined its own network.
•On each additional WCI as it joins the network.
Note: Typically, it takes about 10 minutes for a WCI to join the network. However, the time is
dependent on the distance between the WCIs in network as well as the size and type of
structures that may exist between them.
4. After the network is formed, press the OPEN_NET button on the coordinator to close the
network if it is still open (indicated by an illuminated OPEN_NET LED).
5. To enable and configureTracer SC for the new wireless network, seeTracer SC Online Help and
the current edition of theTracer SC System Controller Installation and Setup guide (BAS-
SVX31).
Establishing the Network Prior to Tracer SC Installation or Without Tracer SC Installation
If aTracer SC has not been installed at the time that you are ready to establish the network or will
never be installed on the network, follow this procedure to establish the network.
Task 1: Activate Communication Among Existing WCIs
1. Choose a centrally located WCI that has been wired to a unit controller to become the network
coordinator.
Note: This WCI will be network coordinator temporarily, if the network is to have aTracer SC
installed on it at a later time. At that time, the WCI that is installed on theTracer SC will
become the network coordinator.
2. Press the START button for 5 seconds to establish the WCI as the coordinator and to open the
network for joining.The yellow CRD LED on the WCI illuminates to identify the WCI as the
network coordinator (see Figure 12, p. 18).
