System Configuration

Components of the YCCS self configure as they come online. The system requires no database commissioning or programming – the System Manager detects all Coordina- tors on the network and displays them to the user. As the Zone Coordinator comes online to the Zone Bus network, it automatically discovers each zone and zone con- troller, then displays them to the user. A relearn function updates which devices are online to the Zone Bus and System Bus. During the relearn process, groups and sched- ules that contain any of the removed devices are also updated.

User Interface Overview

The System Manager and Zone Controller each consist of a colored Liquid Crystal Display (LCD) touch sensitive screen that you use to make all selections. No stylus pen or mouse is required. The display contains a menu-driven interface program that is stored in the embedded firmware. This program enables you to set system parameters, access system information, and monitor and control connected equipment. These oper- ations are available from five screen types that use a common layout. The five types are the Home screen, Alarm screen, Summary screen, Schedule screen, and Setup screen. When you select a screen by touching its icon, the icon turns green, indicating that it is currently active.

System Startup

When the System Manager/Coordinator is powered on, the user interface displays a splash screen with a progress bar to indicate the status of the startup. At this point, the Alarm LED in the upper right corner of the unit is red. Seconds later, the Alarm LED turns green. Finally, the System Manager/Coordinator displays the Home screen (Figure 5 on page 13), which is the starting point for monitoring and controlling the system. The entire startup sequence takes no more than a few minutes.
