Installation, Operation,

and Maintenance

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.

WARNING

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.

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.

Specific requirements, Part 15.4: Wireless Medium Access Control (MAC) and Physical

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.

BAS-SVX40A-EN 9

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).

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).

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.

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.

WCI Addressing

This section describes the WCI 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 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.

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

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:

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 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

Repeater Applications

Note: For more information about the use of repeaters with Wireless Comm, see the Wireless

Comm Network Design Best Practices (BAS-SVX55).

To install a WCI to function as a repeater:

1. Remove power from the controller that is to have the WCI wired to it.

2. Remove the WCI cover by firmly pressing the thumb tab at the bottom of the cover and pulling

the cover away from the back plate (Figure 3, p. 12).

Note: If present, remove the security screw before removing the cover.

3. Secure the backplate to the mounting surface using appropriate hardware. (M3.5 x 20 mm self-

drilling screws are provided.)

4. Attach the 4-connector screw terminal block on the wiring harness to the receptacle on the WCI

(Figure 4).

5. Remove the blue (IMC+) and gray (IMC-) wires from the wiring harness.

6. Connect the red (24 Vdc/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.

Figure 11. Wiring a WCI as a repeater

7. Restore power to the controller.

8. If the WCI communication wire was previously connected to a unit controller, return the WCI

to its default configuration as follows:

a. Set its rotary address switch to 0,0 (the WCI must be powered).

b. Observe its LEDs blink On briefly (<1 second).

c. 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 Additional WCIs

to an Existing Network,” p. 22) or to proceed with establishing a new network (refer to

“Establishing the Network,” p. 17).

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. 10 and “Mounting and Wiring the WCI,” p. 12 sections are complete.

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.

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 Ta bl e 2.

Establishing the Network

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 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

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

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.

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

dependent on the distance between the WCIs in network as well as the size and type

of structures that may exist between them.

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

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.

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.

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.

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).

6. 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).

WCIs as Zone Sensor Receivers

On a WCI that functions as a zone sensor receiver, observe the green SNSR LED illuminate to

confirm association with the wireless zone sensor (see Figure 13).
