Introduction

Read this manual thoroughly before operating or servici ng
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.

The three types of advisories are defined as follows:

WARNI NG

Proper Field Wiring and Grounding
Required!

Failure to follow code could result in death or serious
injury. All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes.

WARNING

CAUTIONs

NOTICE:

Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.

Indicates a potentially hazardous
situation which, if not avoided, could
result in minor or moderate injury. It
could also be used to alert against
unsafe practices.

Indicates a situation that could result in
equipment or property-damage only.

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.

WARNI NG

Personal Protective Equipment (PPE)
Required!

Failure to wear proper PPE for the job being undertaken
could result in death or serious injury. Technicians, in
order to protect themselves from potential electrical,
mechanical, and chemical hazards, MUST follow
precautions in this manual and on the tags, stickers,
and labels, as well as the instructions below:

• Before installing/servicing this unit, technicians
MUST put on all PPE recommended for the work
being undertaken. ALWAYS refer to appropriate
MSDS sheets and OSHA guidelines for proper PPE.

• When working with or around hazardous chemicals,
ALWAYS refer to the appropriate MSDS sheets and
OSHA guidelines for information on allowable
personal exposure levels, proper respiratory
protection, and handling recommendations.

• If there is a risk of arc or flash, technicians MUST put
on all PPE in accordance with NFPA 70E or other
country-specific requirements for arc flash
protection, PRIOR to servicing the unit.

General Information

This section provides general information about the wireless Comm interface (WCI).

Product Description

The Trane® Wireless Comm Interface (WCI) enables wireless communication between system
controls, unit controls, and wireless sensors for the new generation of Trane 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™ 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

Each Trane wireless network can have a total of 31 WCIs (30 member WCIs plus 1 coordinator WCI).
Each network requires one WCI to function as network coordinator.

Quantity of Networks per Tracer SC

A Tracer SC can support up to 8 wireless networks.

Note: For information about installing a WCI on a Tracer SC, see “Mounting and Wiring the WCI,”

p. 12 and Figure 6, p. 14.

Automatic Network Formation

When a WCI is connected to a Tracer 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 all WCIs having matching addresses to automatically join the network.

If no Tracer SC is present, a centrally located WCI must be designated to act as the coordinator. You
can manually set the coordinator WCI so all WCIs having matching addresses automatically join
the network.

Note: For additional information, see “Establishing the Network,” p. 17.

Wireless Zone Sensors

The WCI also communicates with Trane wireless zone sensors, eliminating the need for analog
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.

(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 sheetro ck 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.

8 BAS-SVX40A-EN

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 about WCI placement, see the Wireless Comm Network Design Best
Practices Guide (BAS-SVX55).

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.

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).

CAUTION

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.

Rooftop or air-handling unit

The recommended location is outside of the rooftup or air-handling unit. In outdoor locations, the
WCI should be mounted inside of a plastic enclosure suitable for outdoor use. Kele PS 1811-9 and
TK 1811 are recommended models.

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. 16). When choosing a location
for a repeater WCI, consider the availability of a 24 Vac/Vdc power source to meet its power
requirement.

Coordinator Location

For optimum network performance and reliability, the coordinator WCI should be centrally located
within the network. See the Wireless Comm Network Design Best Practices Guide (BAS-SVX55) for
more detail.

This section describes the WCI addressing scheme and procedure. WCIs can be ordered either pre­addressed 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 two Tracer SCs, with
each Tracer SC communicating on two networks. See Table 1, p. 11 for address settings.

1. Set the left (GRP) rotary address switch for each WCI that is in the same Tracer SC group to an
identical number. (A Tracer SC group refers to all of the networks that communicate with the
same Tracer 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 a Tracer SC group, each network in that group
must have a unique number.

Note: The NET address must match the wireless link on Tracer SC.

Setting Wireless Zone Sensor Receiver Addressing

A WCI 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:

WARNI NG

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 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

Note: The numbers on the WCI rotary address switches are oriented differently from those on

the unit controllers, as the illustration indicates.

Figure 2).

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.

Figure 12. LEDs and buttons related to network formation

BAS-SVX40A-EN 17

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 Tab l e 2 .

Three Ways to Establish a Wireless Network

A wireless network can established:

• After a Tracer SC has been installed.

• Prior to Tracer SC installation.

• On a network that will not have a Tracer SC installed on it.

Establishing the Network After Tracer SC Installation

If a Tracer 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 the Tracer SC.
If multiple WCIs are installed on a Tracer 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 the Tracer SC
as the network coordinator (see Figure 12, p. 17).

2. Observe the yellow OPEN_NET LED illuminate on the coordinator WCI. 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. To extend time on a network that has
not yet closed, press the OPEN_NET button to close the network, then press it again to
open the network for an additional hour. As an alternative, you can use Tracer TU 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 configure Tracer SC for the new wireless network, see Tracer SC Online Help and
the current edition of the Tracer SC System Controller Installation and Setup guide (BAS-
SVX31).

Establishing the Network

Establishing the Network Prior to Tracer SC Installation or Without Tracer SC Installation

If a Tracer 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 a Tracer SC

installed on it at a later time. At that time, the WCI that is installed on the Tracer 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

BAS-SVX40A-EN 19

Figure 12, p. 17).

Establishing the Network

3. Observe the yellow OPEN_NET LED illuminate on the coordinator WCI. 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.

Notes: If the network closes because the timer has expired, you can open the network for an

4. 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.

Notes: Typically, it takes about 10 minutes for a WCI to join the network. However, the time is

5. 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).

Task 2: Installing a Tracer SC After Network Formation

After a Tracer SC is installed on a previously established network, the network must be disbanded
and then re-established. Follow this procedure:

1. On the WCI that is currently the network coordinator, press the START button for 10 seconds.
The network will disband.

2. Install an addressed WCI on the Tracer SC following addressing and wiring instructions (see

“WCI Addressing,” p. 10 and “Mounting and Wiring the WCI,” p. 12).

After power is restored to the Tracer SC, the WCI that is installed on the Tracer SC automatically
becomes the network coordinator and a new network is established.

3. Observe the yellow OPEN_NET LED illuminate on the coordinator WCI. 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

Modifying the Network

This section describes how to modify an established wireless network. Most modifications can be
made by using either the Tracer TU service tool or the WCI.

To use Tracer TU, you must establish communication with a wireless network and attach to a
wireless device. For instructions, see “Appendix: Using the Tracer™ TU Service Tool with Wireless

Networks,” p. 27.

Adding Additional WCIs to an Existing Network

Using Tracer TU

1. After attaching TU to a wireless device, select Open Network from the Wireless menu.

Any WCI with a correct rotary address setting that is located within radio range of a network
member, will join the network.

2. Observe the green NWK LED illuminate on a WCI that joins the network.

Using a WCI

1. Press the OPEN_NET button on any WCI on the network to open the network for joining.

Any WCI with a correct rotary address setting that is located within radio range of a network
member, will join the network.

2. Observe the green NWK LED illuminate on a WCI that joins the network.

Adding Additional Coordinators to a Tracer SC

A Tracer SC can have a total of eight WCIs installed on it. Each WCI installed on a Tracer SC becomes
the coordinator of a separate network. If additional coordinator WCIs/networks are needed on a
Tracer SC after the network has been formed, follow these steps.

1. Remove power from the Tracer SC. (This will not affect the existing networks.)

2. Address the new WCI(s) according to the scheme explained in “WCI Addressing,” p. 10, making
sure the addresses do not conflict with existing WCIs.

3. Install the WCI(s) on the Tracer SC as described in “Mounting and Wiring the WCI,” p. 12,

Figure 6, p. 14, and Figure 7, p . 14. Use a daisy-chain configuration to install multiple WCIs.

4. A new network will be created for each newly installed WCI, with each WCI as coordinator of
the newly created network. Allow sufficient time for all member WCIs to join the new network.

5. Start Tracer SC Device discovery. (Refer to Tracer SC online help for the discovery procedure.)
Devices that previously existed on the wireless network do not need to be rediscovered.

22 BAS-SVX40A-EN

Removing a WCI from a Network

If a coordinator WCI fails, the network ceases to exist. If the other WCIs that were members of the
disbanded network find an open network within radio range, they will try to join that network. To
prevent that from occurring, you can remove WCIs from the network until the coordinator WCI is
replaced.

Using Tracer TU

After attaching Tracer TU to a wireless device:

1. Select Remove from Network from the Wireless menu.

2. Change the rotary address setting on the WCI to prevent the WCI from re-joining the network.

Using the WCI

To remove a member (non-coordinator) WCI, press its START button (10–15 seconds) until the
green NWK LED turns Off.

Note: The same action performed on the coordinator WCI will disband the network.

After the WCI is dropped from the network, the equipment managed by the associated unit
controller is under the direct, local control of the unit controller.

To remove a coordinator WCI, change its rotary address setting.

Modifying the Network

Replacing a WCI on a Network

See “Replacing a Failed WCI,” p. 25.

Closing the Network

To prevent WCIs from joining an open network (indicated by an illuminated OPEN_NET LED), you
can close the network by using Tracer TU or a member WCI.

Using Tracer TU

After attaching Tracer TU to a wireless device, select Close Network from the Wireless menu.

Using a WCI

To close an open network (indicated by an illuminated OPEN NET LED) so that other WCIs cannot
join, push the OPEN NET button on any WCI on the network.

Disbanding a Network

Some rare circumstances may require disbanding the network.

Using Tracer TU

After attaching Tracer TU to the network coordinator, select Disband Network from the Wireless
menu. As the network disbands, the NWK LEDs on all WCIs on the network respond by turning Off.

Using a WCI

Press the START button (for approximately 10-15 seconds) on the coordinator WCI until the yellow
CRD LED and the green NWK LED turn Off. As the network disbands, the NWK LEDs on all WCIs
on the network respond by turning Off.
