communications network.

This guide provides:

• A list of ordering numbers

• A brief overview of the BACnet™ protocol

• BCI-I configuration information

• A explanation of the BCI-I device rotary switches and LEDs

• Data point configuration property definitions

• Tables listing object data points

• Additional resources

• A glossary of terms

Note: Users of this guide should have basic knowledge of BACnet protocol. For more detailed

information about this protocol, visit the company web site listed under “Additional

Resources,” p. 44.

Ordering Numbers

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

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 Ye s .

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

Session of Tracer TU and Direct Connection,” p. 5.

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.

ACC-SVP01B-EN • BCI-I Integration Guide 7

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.

WARNING: Remove power from the HVAC equipment before opening

electrical control panel.

To change baud rate:

1. Establish the connection between Tracer TU and the BCI-I. Follow the procedure,“Starting a

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.

WARNING: Remove power from the HVAC equipment before opening

electrical control panel.

The process for soft setting the device ID is as follows:

1. Establish the connection between Tracer TU and the BCI-I. Follow the procedure,“Starting a

Session of Tracer TU and Direct Connection,” p. 5.

2. From the Utilities drop-down menu, select Controller and then Controller Settings. The

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.

5. Click the 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.

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.

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 Ta bl e 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:

10 ACC-SVP01B-EN • BCI-I Integration Guide

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.

ACC-SVP01B-EN • BCI-I Integration Guide 11

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.

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.

Checking the voltage that is

powering the UC400 is often a

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 out-

of-specification voltage, disconnect

the UC400 and measure the AC

voltage across the transformer.

These measurements can direct the

technician towards the problem

communication problems. If the voltage difference is greater that 7.0 Vac,

some devices will no longer communicate.

Measure AC current

across the current

termination and confirm

that only one end of the

shield conductor is tied to

the earth ground

Vac ≤ 2.0 V

Method 2:

AC voltage between earth ground and device chassis ground- the

chassis ground of the UC400 needs to be connected to earth ground by

some route.

Note: Do not assume that the building frame is a valid earth ground.

Measure AC current

across the current

termination and confirm

that only one end of the

shield conductor is tied to

the earth ground

Vac ≤ 4.0 V

(Must comply with National Electrical

Code™and local electrical codes)
