Home Screens

The Home screen appears when you first activate the System Manager or Zone Coor- dinator by touching its screen. This screen indicates the name and type of device, the current date and time, the software revision, and the outdoor air temperature. The Zone Coordinator Home Screen also shows Zone System Status. After 10 minutes of touch screen inactivity, the local UI times out, the user is logged out, and the screen goes to the Home screen. After 5 more minutes of inactivity (15 minutes total), the screen turns black.
