System S7999B Home Page
A burner or boiler icon is displayed on the page for each Local
burner/boiler system detected. The icon type displayed is
based on the type of system the Local S7999B states that it is.
The name of the burner/boiler system is displayed above the
icon. This system name is also obtained from the Local
S7999B.
The burner or boiler icon on the page is a button that can be
selected by the user to zoom in to show just the components
of that burner/boiler system (burner control, R7999, UDC
controllers, etc.) in the same manner as seen on the Local
S7999B Home page (see Fig. 18). All status pages visible
from the Local S7999B Home page are also accessible after
zooming in on a specific burner/boiler system.
Below each burner or boiler icon one key status variable can
be selected for display. The table below lists the possible
selections the user can choose for display. A different variable
can be displayed for each burner/boiler system.
Fig. 18. System S7999B Home Page.
A fault audio alarm bell button displays in top-left corner of
Local Home page instead of the top-right to accommodate the
Return Back button.
No title is displayed on this page unless specified in User
Preferences. The custom title entered by the user is displayed
on the page when selected by the user.
If you want to go from a Local mode to a System mode (all
burner/boiler systems on the System Home page), press the
Return Back button in the top-right corner of the page (see
Fig. 19). This button is the same icon that displays in the
same position on all pages that have a title.

If more Local burner/boiler systems exist in the network than
can reasonably fit on the page, Previous page and Next page
buttons (see Fig. 20) are used to move between the burner/
boiler systems on the page. These buttons appear only when
the total number of burner/boiler systems exceeds the display
limit. Unlike the switchable S7810M Modbus™ network, no
yellow burner system button is displayed in the top left corner
of the page to switch between burner/boiler systems.
