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.

The three types of advisories are defined as follows:

WARNING

CAUTION s

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.

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.

WARNING

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.

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 evaluation. 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.

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).

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.

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.

BAS-SVX40A-EN 9

WCI Addressing

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.

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:



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.

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.

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

BAS-SVX40A-EN

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

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:

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

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

BAS-SVX40A-EN 19

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:

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.

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.

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 ).

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

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

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.

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

Modifying the Network

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:

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.

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.

BAS-SVX40A-EN 23

Troubleshooting

WCI does not join network

Possible cause

Not enough time allowed for joining.

Wrong address

No power

Too much traffic

Outside of radio range or too many obstacles

Defective WCI

Sensor/unit controller address mismatch

No power

Defective sensor or receiver

Explanation/Resolution

Give the WCI more time to join. If the network closes before the WCI has joined, reopen if necessary by pressing the OPEN NET button.

For factory addressed WCIs, verify addresses with equipment report.

Verify each WCI address after installation.

If sensor is installed, check for error code at sensor.

Initiate network formation and resolve by exception.

Ensure that:

• The WCI is wired correctly.

• The corresponding controller is wired to equipment correctly and is powered On.

Try a different channel. A better channel may be found by trial and error or by using a tool such as WiSpy.

Relocate WCI

Replace

Tracer SC does not communicate with WCI

Possible cause

No power to the WCI
