Chapter 1

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

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 informa-

tion for a particular task. Table 1 on page 3 briefly describes the function

of each button.

Figure 2: Home Screen Components

Note:

You may not have access to all of the tasks presented in this

guide. Your access privileges depend on your user profile. Con-

tact your supervisor for information.

Selection and Navigation Buttons

You navigate through the touch screens by using selection buttons and

navigation buttons (see Figure 3). Selection buttons enable you to select

an item to view or edit. Navigation buttons enable you to page through a

list of items, return to a previous page, or return to the home screen.

Table 2 on page 5 describes the navigation buttons.

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 avail-

able 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).

Title bar

Note:

Navigation of custom screens is not discussed in this guide.

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 exam-

ple of a confirmation screen for changing a setpoint.

The Trane installer or programmer has the option of disabling non-criti-

cal confirmation screens. Consequently, you may not be prompted to con-

firm some changes.

Figure 6: Confirmation Screen for Changing a Setpoint

Press the Custom

Screen View button

to access standard

screens. This button

may or may not

appear on a custom

screen.

Note:

Although confirmations screens are not shown in this guide, all

operator-display procedures are written as if all confirmation

screens are enabled.

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-eight-

digit 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

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 custom-

ized for use at your site (see Figure 5 on page 7).

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 dis-

plays 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).

Standard Screens

If the Trane installer or programmer has not selected custom screens for

use at the operator display, then standard screens are automatically dis-

played. The first standard screen to display after you press the View but-

ton is the View Equipment screen (see Figure 8 on page 10).

Note:

You may not have access to all of the tasks presented in this

guide. Your access privileges depend on your user profile. Con-

tact your supervisor for information.

Note:

Standard screens are available with most, but not all, Tracer

Summit equipment (see Appendix B on page 67).

Note:

Navigation of custom screens is not discussed in this guide.

Viewing and Changing System Status Information

10 BMTW-SVU02C-EN

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.

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 equip-

ment 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 build-

ing area. In this example, you use the area sort method to view the oper-

ating 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.

Note:

The building area sort method only appears if the Trane

installer or programmer has assigned areas to the operator dis-

play.
