BCU Operator Display
Overview

The BCU operator display is a liquid crystal display (LCD) touch screen.
It is installed in Tracer Summit BMTW building control units (BCUs) as
an option (see Figure 1). The operator-display touch screen enables you to
perform most of the Tracer Summit PC Workstation daily activities at the
BCU. The Tracer Summit workstation is the PC software program that
enables you to control and monitor the operation of HVAC equipment in
your building.

From the operator-display touch screen you can perform the following
tasks:

• View and manage alarms and events

• View and change setpoints

• Override schedules and equipment

• Modify schedule start times and stop times

• Maintain and calibrate the display

BCU Operator Display Overview

Operator Display Screens

The operator-display touch screen can display both standard and custom
screens, confirmation screens, and a security screen.

Standard Screens

Standard screens are a part of the Tracer Summit BCU operator display
software. (See Appendix B on page 67 for a list of standard screens avail­able at the operator display.) Standard screens are identified by a title bar
at the top of each screen (see Figure 4). .

Figure 4: Standard Screen—Example

Title bar

Custom Screens

The Trane installer or programmer can create custom screens for use at
the operator display. These screens can be used in place of standard
screens to accomodate specific user requirements at your facility. Custom
screens can be linked to standard view screens by a navigation button
(see Figure 5 on page 7).

Note:

Navigation of custom screens is not discussed in this guide.

Using the Touch Screen

Figure 5: Custom Screen—Example

Press the Custom
Screen View button
to access standard
screens. This button
may or may not

screen.

Confirmation Screens

A confirmation screen asks if you wish to proceed with an operation. This
type of screen appears after you make a change to system status (for
example, change a setpoint or edit a schedule). Figure 6 shows an exam­ple of a confirmation screen for changing a setpoint.

The Trane installer or programmer has the option of disabling non-criti­cal confirmation screens. Consequently, you may not be prompted to con­firm some changes.

Note:

Although confirmations screens are not shown in this guide, all
operator-display procedures are written as if all confirmation
screens are enabled.

Viewing and Changing System Status
Information

You can display and change system status information using the BCU
operator-display view function. The view function enables you to:

• View equipment status

• Change setpoints

• Override equipment controls

Note:

You may not have access to all of the tasks presented in this
guide. Your access privileges depend on your user profile. Con­tact your supervisor for information.

View Screens

There are two types of view screens associated with the operator-display
view function: custom and standard screens. Standard screens are a part
of the Tracer Summit BCU operator-display software (see Figure 4 on
page 6). Custom screens are created from a screen template and custom­ized for use at your site (see Figure 5 on page 7).

Note:

Standard screens are available with most, but not all, Tracer
Summit equipment (see Appendix B on page 67).

Custom Screens

If the Trane installer or programmer has selected custom screens for use
at the operator display, then a custom screen is the first screen that dis­plays after you press the view button on the home screen. Custom screens
can be linked to standard screens by the use of a navigation button (see
Figure 5 on page 7).

Note:

Navigation of custom screens is not discussed in this guide.

Standard Screens

If the Trane installer or programmer has not selected custom screens for
use at the operator display, then standard screens are automatically dis­played. The first standard screen to display after you press the View but­ton is the View Equipment screen (see Figure 8 on page 10).

BMTW-SVU02C-EN 9

Viewing and Changing System Status Information

Figure 8: View Equipment Screen

The View Equipment screen enables you to view equipment status by
using three different sort methods: Building Area, Name of Equipment
and Equipment Type.

Note:

The building area sort method only appears if the Trane
installer or programmer has assigned areas to the operator dis­play.

Using the View Screens

There are three sort methods for viewing and changing system status:

• View by building area

• View by name of equipment

• View by equipment type

Use the sort method most convenient for you to quickly get to the equip­ment you need to monitor or control.

The following sections briefly discuss each method.

View by Building Area

Figure 9 on page 12 shows an example of how to view equipment by build­ing area. In this example, you use the area sort method to view the oper­ating conditions for a VAV box that controls the space for Conference
Room C. This sort method assumes you are familiar with the building
area. The step-by-step procedure for viewing equipment by building area
is found on page 15.

Using the View Screens

View by Name of Equipment

Figure 10 on page 13 shows an example of how to view equipment by
using the equipment name. This sort method assumes that you know the
equipment by name. The step-by-step procedure for viewing by equip­ment name starts on page 16.

View by Equipment Type

Figure 11 on page 14 shows an example of how to view equipment by
equipment type. This sort method assumes that you know the equipment
type and name. The step-by-step procedure for viewing by equipment
type is found on page 16.

Handling Alarms and Events

The BCU operator display can display all alarms and events received by
the BCU event log. The BCU event log is a list of the 100 most recent
alarms and events sent to the BCU. The event log lists alarms and events
in the order they are received, with the most recent alarms and events
displaying at the top of the event log.

• Alarms notify you when heating, ventilating, and air conditioning

(HVAC) equipment is not operating correctly. For example, an alarm
is generated when communication is down between an HVAC unit
and the BCU or when a filter on an HVAC unit is dirty.

• Events notify you when an action that you need to keep track of

occurs. An example of an event is when communication is restored
with an HVAC unit.

The event log is automatically updated with new alarms and events when
you press the Alarms button on the home screen. The display also auto­matically updates if you are on the first page of the event log when it
receives new events or alarms.

Note:

You may not have access to all of the tasks presented in this
guide. Your access privileges depend on your user profile. Con­tact your supervisor for information.

BMTW-SVU02C-EN 27

Handling Alarms and Events

Alarm Notification

When the operator display receives a new alarm or event, the indicator
light on the display flashes red until all the events in the log have been
viewed. Figure 24 shows the location of the indicator light.

Figure 24: Alarm Indicator

Indicator light

The Trane installer or programmer can set up alarms and events to beep
when they are received by the operator display. The speaker on the BCU
will beep until you press the Alarms button on the home screen. If you
exit the event log with an unacknowledged alarm or event, the system
will reset the beep-timer to beep again in 60 minutes.

Using the Alarms and Events Screens

There are three screens associated with viewing and acknowledging
alarms and events.

These screens are:

• Event log

• Event Details #1

• Event Details #2

Note:

The screen names listed above do not appear on the operator­display screens. Descriptive screen names have been assigned
to help identify each screen.

Figure 25 on page 29 provides basic information about the alarms and

Chapter 4

Displaying and Editing
Schedules

The BCU operator display schedule function enables you to view and edit
schedules. Schedules available at the operator display have been selected
for viewing and editing by the Trane installer or programmer.

A schedule is a set of events (instructions) that tells the HVAC (heating,
ventilating, air conditioning) equipment connected to Tracer Summit
what to do and when to do it. For example, an event in a schedule tells a
rooftop unit when to turn on or off.

There are three types of events in a schedule:

• Daily Events: These types of events occur every day, unless you over-

ride them with an exception. (An example daily event is a change in
building occupancy at 6 P.M.) Each day of the week can have separate
events scheduled. Any combination of days can share the same
events. For example, Monday, Wednesday, and Friday can have the
same events, and Tuesday and Thursday could each have a different
set of events or share the same events.

• Holidays: The Trane installer or programmer creates and assigns

these types of events in the Tracer Summit software. (An example of a
holiday would be New Year’s Day or some other designated day.)

You can change the events scheduled for a holiday, but you cannot cre­ate or delete a holiday from the operator display. The Trane installer
or programmer creates and deletes holidays from a schedule on a
Tracer Summit PC Workstation.

• Exceptions: These types of events override both daily events and

holidays. Like a holiday event, you can define specific days that the
exception will override.

Note:

You cannot create or delete schedules or holidays from the oper­ator display. These activities are performed in the Tracer Sum­mit software.

Changes made to schedules from either the operator display or
from a Tracer Summit PC Workstation are automatically
updated the next time the PC Workstation is online with the
site.

BMTW-SVU02C-EN 31

Displaying and Editing Schedules

Using the Schedule Screens

There are nine screens associated with viewing and changing
schedules. These screens are:

Schedule list

• Calendar

• Basic events

• Detailed events

• Events editor

• Select dates

• Other date

• Items Scheduled

• Add or Remove

Note:

Most of the screen names listed above do not appear on the
operator-display screens. Descriptive screens names have been
assigned to help identify each screen.

The following sections provide examples for using the schedule screens to
view and edit schedules.

Viewing a Schedule

Figure 26 on page 33 shows an example of how to use the scheduling
screens to view a schedule. The step-by-step procedure for viewing sched­ules is found on page 35.

In this example, you select the Administration Normal schedule from the
list and then view the events scheduled for September 5, 2001. Scheduled
events display on either the basic events screen or the detailed events
screen. Because there are only two events scheduled and the events are
neither night economize nor analog setpoints, the basic events screen dis­plays. However, you can still access the detailed events screen by pressing
the Detailed View button.

Editing a Schedule

Figure 27 on page 34 shows an example of how to edit a schedule from the
detailed events screen. This screen is the default events screen when
there is more than two events scheduled or the events are either night
economize or analog setpoints. The step-by-step procedure for editing
schedules start on page 38.

In this example, you change the event start and stop times and then
apply the change to the weekly schedule.
