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 Figure 1: BCU Operator Display Operator-display touch screen BMTW BCU BMTW-SVU02C-EN 1
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.

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. 6 BMTW-SVU02C-EN
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 appear on a custom 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. Figure 6: Confirmation Screen for Changing a Setpoint BMTW-SVU02C-EN 7
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.

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

Chapter 3 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 events screens. The screens listed above are shown in the order that they appear on the operator display. The step-by-step procedures for viewing, acknowledging, and deleting alarms and events are found on page 30. 28 BMTW-SVU02C-EN

For unacknowledged alarms or events, you must first acknowledge the event before you can delete it. 30 BMTW-SVU02C-EN
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. 32 BMTW-SVU02C-EN
