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

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 

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. 

Title bar

Figure 5: Custom Screen—Example 

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.

Chapter 2 

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: 




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 


Note: 

Navigation of custom screens is not discussed in this guide. 


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. 

10 BMTW-SVU02C-EN

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: 




BMTW-SVU02C-EN 27


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 

events screens. The screens listed above are shown in the order that they 

appear on the operator display.

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 override 

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.
