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
Using the Touch Screen
The operator-display touch screen uses five different screen types, as well
as selection buttons and navigation buttons to view and change system
status information. The five screen types are the home screen, standard
screens, custom screens, confirmation screens, and the security screen.
Home Screen
The home screen is where each operator display task begins. It includes
five task buttons: View, Alarms, Schedule, Timed Override, and Setup
(see Figure 2). These buttons enable you to access system status information for a particular task. Table 1 on page 3 briefly describes the function
of each button.
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.

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

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.

BCU Operator Display Overview
Security Screen
The operator-display security screen appears when a password is
required to edit a task (see Figure 7). The password is a four-to-eightdigit number. Contact your supervisor for more information.
Figure 7: Security Screen
To enter a password:
1. Enter your password by pressing the numerical keys.
2. Press the OK button to display the edit screen. (An edit screen is any
screen that allows you to change or edit system status information.)
Note:
To clear your entry, press the Clear button. To cancel your entry
and return to the previous screen, press the Cancel button.

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:
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.
10 BMTW-SVU02C-EN
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.

Viewing System Status Information
Use the following procedures to view equipment status using one of the
three sort methods:
• Viewing equipment by building area
• Viewing equipment by equipment name
• Viewing equipment by equipment type
Viewing Equipment by Building Area
All operator tasks begin at the home screen (See “Home Screen” on
page 2).
1. From the home screen, press the View button. The View Equipment
screen displays (refer to Figure 10 on page 13).
Note:
To access the View Equipment screen from a custom screen,
press the Custom Screen View button (see Figure 5 on page 7).
2. Press the Building Area button. The View-By Area list displays, listing in alphabetical order the areas that are available at the BCU
operator display.
Note:
The Building Area button will not display if areas have not
been assigned to the operator display.
3. Press an area to display the Members screen. (Members are pieces of
equipment that belong to a group, in this case an area.)
4. Press a member name to view status information about that piece of
equipment. The unit control module (UCM) main screen displays for
that equipment. You can only view information from this screen. To
change system information, see “Changing System Values” on
page 18.
Note:
Some equipment may not have a UCM main screen, More
Details screen, or Unit Summary information associated with
it.
The UCM main screen may or may not have a graphic (picture
of the equipment) associated with it.
5. To return to the home screen, press the Home button.
