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 Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTIONsIndicates 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.
NOTICE Indicates a situation that could result in
equipment or property-damage only
accidents.
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
and HCFCs such as saturated or unsaturated HFCs and
HCFCs.
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 according to local rules. For
the USA, 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 required for the work being
undertaken (Examples; cut resistant gloves/sleeves,
butyl gloves, safety glasses, hard hat/bump cap, fall
protection, electrical PPE and arc flash clothing).
ALWAYS refer to appropriate Safety Data Sheets
(SDS) and OSHA guidelines for proper PPE.
• When working with or around hazardous chemicals,
ALWAYSrefertotheappropriateSDSandOSHA/GHS
(Global Harmonized System of Classification and
Labeling of Chemicals) guidelines for information on
allowable personal exposure levels, proper
respiratory protection and handling instructions.
• If there is a risk of energized electrical contact, arc, or
flash, technicians MUST put on all PPE in accordance
with OSHA, NFPA 70E, or other country-specific
requirements for arc flash protection, PRIOR to
servicing the unit. NEVER PERFORM ANY
SWITCHING, DISCONNECTING, OR VOLTAGE
TESTING WITHOUT PROPER ELECTRICAL PPE AND
ARC FLASH CLOTHING. ENSURE ELECTRICAL
METERS AND EQUIPMENT ARE PROPERLY RATED
FOR INTENDED VOLTAGE.

WARNING
Follow EHS Policies!
Failure to follow instructions below could result in
death or serious injury.
• All Trane personnel must follow the company’s
Environmental, Health and Safety (EHS) policies
when performing work such as hot work, electrical,
fall protection, lockout/tagout, refrigerant handling,
etc. Where local regulations are more stringent than
these policies, those regulations supersede these
policies.
• Non-Trane personnel should always follow local
regulations.

BACnet Protocol
The Building Automation and Control Network (BACnet
and ANSI/ASHRAE Standard 135-2004) protocol is a
standard that allows building automation systems or
components from different manufacturers to share
information and control functions. BACnet provides
building owners the capability to connect various types of
building control systems or subsystems together for a
variety of reasons. In addition, multiple vendors can use
this protocol to share information for monitoring and
supervisory control between systems and devices in a
multi-vendor interconnected system.
The BACnet protocol identifies standard objects (data
points) called BACnet objects. Each object has a defined
list of properties that provide information about that
object. BACnet also defines a number of standard
application services that are used to access data and
manipulate these objects and provides a client/server
communication between devices. For more information
on BACnet protocol, refer to “Additional Resources,” p. 22.
BACnet Testing Laboratory (BTL) Certification
The BCI-R supports the BACnet communication protocol
and has been designed to meet the requirements of the
application-specific control profile. For more details, refer
to the BTL web site at www.bacnetassociation.org.

Understanding Rotary Switch
Values and BACnet Device IDs
Rotary Switch Values
The rotary switch value is the physical address of a device
on a network. It is often referred to as the MAC address.
The term is generic and is used to denote the physical
address of many types of networks.
For example, the rotary switch value of a BACnet MS/TP
network has a valid range of zero (0) to 255 and can be
represented by a single byte. The rotary switch value of an
Ethernet network is six bytes in length. Each device must
be assigned a unique rotary switch value. Failure to assign
a unique address to each device will result in
communication errors.
BACnet Device ID
The BACnet Device ID uniquely identifies each BACnet
device as a logical address. The valid range of this address
is 0 to 4194303. The logical address in an Internet Protocol
(IP) network is the IP address, which is four bytes in length
and is typically written in the format of 192.168.1.125.
Failure to assign unique address to each device will result
in communication errors.
Tracer SC uses the rotary switch value to create the BACnet
device ID. The Tracer SC adds an SC rotary switch address
and a link number to artificially create a unique BACnet
Device ID for each node.
Figure 15, p. 18 shows how Tracer TU displays the rotary
dial settings and the resulting BACnet device ID:
• The rotary switch values on the BCI-R are set to 30
(0,3,0).

Configuring the BCI-R
18 RF-SVN03F-EN
• The Tracer SC created a BACnet device ID of 101030.
• The Tracer SC address is “0,1,0”.
• The BCI-R is installed on link 1.

RF-SVN03F-EN 19
What To Do After Adding Options
or Equipment to the Unit
Restoring the BCI-R controller to factory defaults is
necessary if the unit setup has changed after the initial self-
configuration process. This process is called “clearing the
controller”.
For example, an economizer was added to the machine
after the initial installation. In order for the BCI-R controller
to recognize the economizer, it must be restored to factory
defaults.
The BCI-R controller self-configures upon initial power-up
to match the connected equipment type. This
configuration is then permanently stored in the memory of
the controller. Through this process, the controller
generates the correct list of BACnet points.
Clearing the Controller and Restoring
Factory Defaults to the BCI-R
Clearing the controller is necessary to collect equipment
information and reinstall the configuration.
Using the BACnet Setup Tool to clear the
controller and restore to factory defaults
1. Navigate to the Controller Settings screen.
2. Click within the light gray area at the bottom left of the
screen just above the "Connected" indicator.
The Clear Controller button appears at the top right of
the screen.
3. Click Clear Controller.
Amessage box appears stating that the configuration
will be reset (deleted).
4. Click OK.
When the controller is cleared, the Select Device Units
message box appears.
5. Click OK and then expand the Controller Units box on
the Controller Settings screen.
6. Select the units (SI, IP, or Custom).
Note: This selection defaults to Custom after clearing
the controller. If you want to use Custom,
ensure that all unit options are set correctly.
7. Click Save.
Using Tracer TU to clear the controller and
restore to factory defaults
1. Establish the connection between Tracer TU and the
BCI-R controller.
2. Select the Controller Settings Utility tab from the
vertical tab set located on the right side of the TU
window.
3. On the controller settings page, there is a gray bar at
the bottom with the Save/Cancel buttons. Move the
cursor near the left edge of the gray bar, keeping the
cursor inside the bar; click on this area. A Clear
Controller button will appear in the upper right portion
of the screen display.
4. Click the Clear Controller button and a pop-up window
will appear with a message that asks for confirmation
to reset the device. Click Yes.
5. A pop-up window will appear confirming that the
controller has been reset and that the controller will be
restarted. Click OK. The BCI-R controller is restored to
its factory default state after it restarts.
6. Follow the steps in “Configuring the BCI-R” to
reconfigure the controller.
Updating the Application Code
The application code in the BCI-R controller can be
upgraded in the field by using Tracer TU. Follow the
instructions in Tracer TU to upgrade the application code.

Managing Device Units on the
Controller Units Screen
The BCI-R device units can be viewed and managed on the
Controller Units screen from either the BACnet Setup Tool
or Tracer TU.
When the BCI-R first powers up, or after the controller has
been cleared, a list of points (the role document) is created
from the information supplied to the BCI-R from the
ReliaTel RTRM module through the Modbus link.
Note: The BCI-R creates the role document immediately
(often within one second).
Immediately after the points are created, the device units
are set and saved and appear on the Controller Units
screen. The values that correspond to the device units are
set to default to SI values. In some cases, the Custom radio
button may be selected; however, the device units will still
default to SI.
If you are using Tracer TU to change the Device Units to IP
by clearing the controller, it is best to either unplug the
Modbus cable to the BCI-R, or to power down the entire
unit (the BCI-R). By doing this, the BCI-R will not see
Modbus traffic. This method will enable the Device Units
radio button selection, which allows you to make changes.
