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. 44.
BACnet Testing Laboratory (BTL) Certification
The BCI-I 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.

BCI-I Configuration
BCI-I Configuration
This section will provide the following information when configuring the BCI-I:
•
Overview
•
Starting a session of Tracer TU and direct connection
•
Resetting to factory default
•
Configuring IP units
•
Configuring BACnet objects
•
Changing baud rate and device ID
•
Input/output and equipment functions
Overview
The BCI-I device is designed as a self-configuring controller to accommodate the many possible
equipment configuration options available in the IntelliPak line of equipment. This self-configuring
device eliminates the need for the BAS technician having to create BACnet objects, minimizes the
risk of object configuration errors, and allows the IntelliPak unit to be quickly installed in the BAS.
The self-configuration process only creates objects that are appropriate for the feature set of the
specific IntelliPak unit the BCI-I is connected to. Once this process is complete, the device exits
factory mode and enters the normal mode of operation. At this point, the self-configuration process
will not start when power is applied to the device.
The set of objects listed in Table 3, p. 24 through Table 10, p. 31, are the super set of all possible
objects supported by the IntelliPak line of equipment. The BAS technician should query the device
for the list of actual objects that have been created in the device.
Starting a Session of Tracer TU and Direct Connection
Tracer TU is the service tool software that allows the technician to modify the operation of the
device and to discover the BACnet objects present in the device. To modify the device or discover
objects, the user must first connect to Tracer TU as follows:
WARNING: Remove power from the HVAC equipment before opening
electrical control panel.
1. Connect a USB cable directly between the laptop PC and the service port located on the front
of the BCI-I device. When connecting to the controller for the first time, the Found New
Hardware Wizard appears. Follow the wizard instructions to install the USB hardware driver.
2. Click either the Tracer TU desktop icon or the Tracer TU program item in the Tracer TU group
on the Start menu. The Tracer TU splash screen appears briefly followed by the Connect
dialog box.
3. Select the Direct Connection (Via USB cable) radio button if it is not already selected.
4. Click the Connect button and the Tracer TU main page will appear after successful connection.
Note: The BCI-I may be powered via the USB cable or 24 Vac from the HVAC unit. Concurrent
connection of unit power and the USB cable will not harm the BCI-I device.
For more detailed information about direct connection to Tracer TU, refer to the Tracer™ TU Service
Tool Getting Started Guide (TTU-SVN02) (X39641083).

BCI-I Configuration
Reset to Factory Default
Factory default mode is the only mode the technician can use to set the units of measure for the
device or to scan the IntelliPak unit to create BACnet objects. The process of putting the device in
factory default mode must be run prior to executing units of measure configuration or the object
self-configuration process.
WARNING: Remove power from the HVAC equipment before
opening electrical control panel.
To reset the controller to factory default/unconfigured state:
1. Power down the unit. The IMC buss must not be active during reset.
2. Establish the connection between Tracer TU and the device. Follow the procedure, “Starting a
Session of Tracer TU and Direct Connection,” p. 5.
3. From the Utilities menu, select Controller and then Controller Settings. The Controller
Settings page appears.
4. On the controller settings page there is a gray bar at the bottom with Save/Cancel buttons.
Move the cursor near the left edge of the bar, keeping the cursor inside the bar. Click on this area
and a Clear Controller button will appear in the upper right portion of the page.
5. Click the Clear Controller button and a pop-up window will appear asking for confirmation to
reset the device. Click Yes.
6. After a few seconds a pop-up will appear confirming that the controller has been reset and
indicating that the controller will be rebooted. Click OK.
After the controller boots up, it will be in factory default state. The units of measure is SI (metric),
the MS/TP baud rate is 76,800, and there will be no BACnet objects present in the controller.
The controller must be in this state prior to changing the units of measure or self-configuring
the device. If using inch-pound units of measure, proceed to the next section, “IP Units
Configuration, otherwise, proceed to “BACnet Object Configuration.
IP Units Configuration
The BCI-I supports both inch-pound and SI (metric) units of measure. The factory default units of
measure is SI. The device allows only a change of units for all objects as a whole. Mixed units of
measure is not allowed. If the controller is not in factory default state, follow the previous
procedure, “Reset to Factory Default,” p. 6.
To change the units of measure in the device:
1. Establish the connection between Tracer TU and the BCI-I. Follow the procedure,“Starting a
2. From the Utilities drop-down menu, select Controller and then Controller Settings. The
page contains four configuration frames that are minimized. Expand the Controller Units
frame.
3. In the Device Units box of the frame, select IP units of measure radio button and then click
Save button in the lower right corner of the window. A pop-up will display indicating that
changes were saved to the controller. Select OK.
4. Exit Tracer TU and cycle power to the controller by disconnecting the USB plug and then
reconnecting the plug. After the controller boots up, it will be in factory default state, the units
of measure is IP, the MS/TP baud rate is 76,800, and there will be no BACnet objects present in
the controller.

BCI-I Configuration
BACnet Object Configuration
Configuring BACnet objects is a self-configuring process. If the controller is not in factory default
state, follow the previous procedure, “Reset to Factory Default,” p. 6.
1. Remove the USB cable plug from the device.
2. Apply power to the HVAC equipment. After the device boots up, the self-configuration process
will begin. No further user action is required.
Note: Do not remove power while the device is in self-configuration mode. This typically takes
2 to 4 minutes to complete. Once complete, the device enters normal operating mode.
Change Baud Rate
The BCI-I device supports four baud rates: 9600, 19200, 38400, and 76800 baud. The default baud
rate is 76800 baud. The baud rate can be modified with Tracer TU.
To change baud rate:
page contains four configuration frames that are minimized. Expand the Protocol frame.
3. Click on the drop down arrow for the Baud Rate list and select the desired baud rate.
4. Click Save button in the lower right corner of the window. A pop-up will display indicating that
changes were saved to the controller. Click OK.
5. Exit Tracer TU and disconnect the USB cable plug.
6. Apply power to the HVAC equipment.
Change Device ID
By default, the BCI-I device sets its device ID to the same value as the one defined by the rotary
switches (MS/TP MAC address) on the front of the device. Refer to the section, “Rotary Switches,”
p. 12. For simple networks, this is an easy method to guarantee unique device IDs across the link.
The device also supports the full range of device ID values as specified by the BACnet Standard.
Systems that require a more complex device ID convention are supported with Tracer TU, which
has the ability to set the device ID via software configuration.
The process for soft setting the device ID is as follows:
page contains four configuration frames that are minimized. Expand the Protocol frame.
3. In the device ID box, select the check box next to Use Software Device ID to enable the
functionality. The swipe-and-type box becomes available.

that changes were saved to the controller. Click OK.
6. Exit Tracer TU and disconnect the USB service plug.
7.
Apply power to the HVAC equipment.
Stand-alone or BAS Operation
The control system on HVAC equipment has the ability to operate the unit as a stand-alone system
or as part of a building automation system. The BCI-I (either factory or field installed), by default,
is configured for stand-alone operation. This configuration enables the HVAC equipment to operate
prior to the commissioning of the unit into the BAS.
IntelliPak Control Configuration
The IntelliPak control system must be configured at the human interface (HI) to support unit control
from the BAS. The technician should set/verify the following configuration properties as illustrated
below. The technician should also verify that the BAS Module Comm Failure diagnostic is not
present.

BAS Unit Control
The BCI-I provides a method for a BAS to control the operation of HVAC equipment. This method
consists of BACnet objects that the BAS can access to control and monitor the status of equipment.
There are two sets of objects:
•
Output objects; used by the BAS to provide command, setpoint, and sensor information to the
IntelliPak unit.
•
Input objects; provide IntelliPak status information to the BAS. See tables 3 to 11 for the list of
objects supported.
The system allows the BAS technician to define the amount of control that the BAS system will
apply to the unit. This is done by configuring the state of the Out of Service property of the output
objects. If the property is set to True, the equipment will use a corresponding local value for control.
If the property is set to False, the local value is ignored and the BAS-supplied value is used for
control. The BAS value is provided to the IntelliPak by writing to the present value property of the
corresponding output object. The factory default value for the Out of Service property of these
objects is True.
8
BCI-I Configuration
Periodic Update of BAS Values
The BCI-I device requires the BAS system to provide a periodic update to the sensor values. This
is required to protect against a loss of communication between the BAS and the BCI-I. By BACnet
definition, the present value of the object will maintain the last value written to it, regardless of the
amount of time that has elapsed since the last write. If communication is lost for several minutes
or longer, the present value of BAS-supplied sensor objects may no longer represent the current
state of environmental conditions. This may result in decreased occupant comfort and damage to
building systems.
BAS Communication Failure
The BCI-I is designed to minimize communication failure mode. It does this by monitoring the
length of time that has elapsed since the last write to the present value of the sensor object. If the
length of time exceeds a predefined limit, the BCI-I will place the object into the fault state and revert
to a unit-supplied sensor value for control. At power up, the sensor objects are set to a fault state
and they will remain in this state until a write is detected. The minimum periodic refresh rate for
the objects is defined in Table 3, p. 24. The following list is a set of sensor values that can be
supplied by the BAS:
•
Space Static Pressure BAS
•
Space Air Temperature BAS
•
Discharge Air Temperature BAS
•
Duct Static Air Pressure BAS
•
Outdoor Air Temperature BAS
•
Outdoor Air Humidity BAS
•
Outdoor Airflow BAS
•
Space CO2 Concentration BAS
•
Space Humidity BAS
Input/Output Commands and Calculations
This section will provide the following information about certain inputs and outputs that perform
unique control commands and calculations:
•
System control command
•
Filter timer and diagnostic reset commands
•
Setpoint calculations
System Control Command
Binary Output Object 1, has a special importance in the system. The object allows the BAS to
command the unit to run in a local or BAS control mode. When the present value property of the
object is set to Local Control, the IntelliPak unit will enter local control and ignore BAS supplied
values. In this mode, the unit will use local sensor and setpoint values. When the object present
value property is set to BAS Control, the IntelliPak unit will use the values supplied by the BAS
system for unit control.
Filter Timer Reset Command
The BCI-I uses the Filter Runtime Hours object (AI 6) to generate a diagnostic when its present value
is greater than the Filter Runtime Hours Setpoint, (AV 1) present value. The procedure for resetting
the timer is as follows:
9
BCI-I Configuration
The BAS will change the state of the Filter Timer Reset Command object (BO 13) to the active
state. Upon the change to active state, the BCI-I will set the present value of the Filter Runtime
Hours object to zero and then set the Reset Command object back to the inactive state.
Diagnostics Reset Command
The IntelliPak control system monitors the operation of the HVAC equipment. If an abnormal
condition is detected, a diagnostic message is displayed on the human interface of the equipment
control panel. In addition, the set of internal diagnostics is mapped to the set of BACnet binary input
objects, as listed in Table 9, p. 31. The corresponding BI object will change state from inactive to
active when the diagnostic is detected. The object has been configured to send a BACnet event
message to external BACnet devices as defined by the protocol.
The BAS has the ability to reset internal diagnostics by controlling the state of the Diagnostic Reset
Command object (BO 14). The procedure for resetting diagnostics is as follows:
The BAS will change the state of the Diagnostic Reset to the active state. Upon the change to
active state, the IntelliPak control system will reset all internal diagnostics and set the state of
all of the diagnostic objects to inactive. Upon completion of this action, the BCI-I will set the
present value of the Diagnostic Reset Command object back to the inactive state.
Setpoint Calculations
The equipment has the ability to perform two basic control functions:
•
Space air temperature control
•
Discharge air temperature control
When the unit is configured for discharge air control, it controls the temperature of the air leaving
the unit to the discharge air temperature setpoint.
When the unit is configured for space air temperature control, it controls the air temperature of the
space that contains the space air temperature sensor. This value may be provided by wiring the
sensor to the unit or via a sensor value provided by the BAS.
The drawing below describes how the various temperature setpoints are calculated for space
temperature control. When the unit is in an occupied mode the active space temperature setpoint
is calculated based on the space temperature setpoint and the two setpoint offset values. In
unoccupied mode, the unoccupied heating and cooling setpoints are used as the active setpoint.
10
BCI-I Configuration
Timestamp Configuration
The BCI-C device has a software-derived clock that maintains the time and date. The device requires
the current time to enable it to record a timestamp when an event or a change in state is detected
by a BACnet object. However, in the event of a power loss, the device does not maintain this time
and date information. At powerup, the device time and date will default to 12:00 pm., Jan 1, 1970.
To minimize the possibility that the unit timestamp is not representing the actual time, the BAS
should be setup to periodically synchronize the device time clock with the BAS clock using the
BACnet TimeSynchronization service.
11
BCI IntelliPak Rotary Switches and LEDs
This section provides information about the BCI-I rotary switches and LED displays.
Rotary Switches
There are three rotary switches on the front of the BCI-I device that are used to define a three-digit
address when the BCI-I is installed on a BACnet communications network. The three-digit address
setting is the BACnet MAC address.
Note: All devices are MSTP masters with valid MAC addresses of 001 to 127 for BACnet.

General Information
Checkout Procedure
Checking the voltage that is
powering the UC400 is often a
Step 1
necessary step when commissioning
or troubleshooting. Operational
issues and LED operation may result
in a need to measure the input
power.
When troubleshooting, it is faster to
take measurements while the load is
in place. If Step 1 indicates an outof-specification voltage, disconnect Step 2
the UC400 and measure the AC
voltage across the transformer.
These measurements can direct the
technician towards the problem
source.

ASHRAE
See American Society of Heating, Refrigeration, and Airconditioning Engineers
American Society of Heating, Refrigeration, and Airconditioning Engineers
An international organization of 50,000 persons with
chapters throughout the world. The Society is organized
for the sole purpose of advancing the arts and sciences of
heating, ventilation, air conditioning and refrigeration. It
benefits the public with its research, standards writing,
continuing education, and publications.
advocates BACnet protocol for use in system-level control
devices.
device
A device is a standard BACnet object as defined by
ASHRAE Standard 135-2004.The Tracer UC800 contains
the BACnet object.
Device ID
The Device ID is used to uniquely identify each BACnet
Device and it can be in the range of 0 to 4194302. There
cannot be more than one device using the same Device
ID. Each of the sample applications operate as a device
and requires its own device id which defaults to zero.

interoperability
The ability to integrate equipment from different vendors
into a comprehensive automation and control system. In
addition, digital communications between products
designed independently, but designed to the same
communication standard.
BACnet interoperability building blocks
A block of BACnet application services that tells vendors
what BACnet services must be implemented to provide
specific device functionality. The BIBBs are grouped
together into BACnet device profiles.
P
BACnet object
An abstract representation of the physical point or points
where data is input from or output to an I/O device. Each
object may have several BACnet properties that describe
the status of that object.
protocol
A set of rules (language) that governs the exchange of
data over a digital communications system.
baud rate
The number of signaling elements that occur each second
during electronic data transmission. At slow speeds, baud
indicates the number of bits per second that are
transmitted. For example, 500 baud means that 500 bits
are transmitted each second (abbreviated 500 bps). At
higher speeds, multiple bits may be encoded with each
electrical change. For example, 4,800 baud may allow
9,600 bits to be sent each second. Data transmission
rates at high speeds are generally expressed in bits per
second (bps) rather than baud. For example, a 9,600 bps
modem may operate at only 2,400 baud.
stand-alone operation
Equipment is running in a stand-alone mode when all
control is provided by the equipment's electronic control
system. The system controls the building environment to
a local set of configuration and setpoint values. It monitors
the environmental conditions via sensors that are
physically wired to the unit's control system.
