Each UDC controller icon is a button that the user selects to
advance to a status page that displays information about just
the UDC controller selected. Information displayed varies by
controller type.
Up to 6 UDC controllers can display on the page at one time. If
the Local burner/boiler system has more than 6 UDC
controllers, then "Right" and "Left" arrows will appear on either
side of the screen, allowing the user to scroll to view the
additional UDC controllers.
When 2 or more S7810M Modbus Modules are connected to a
Com port, 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 "Installation type" (Burner system or
Boiler system) that was selected under the "General" tab on
the Display Setup page. The name of the burner/boiler system
is displayed above the icon. The user can input the system
name on the "Control Setup" page using the "Rename Boiler"
button.
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 single
system. All status pages visible from the single system 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. (See "Boiler key variable selection" on
page 19 for details). Table 3 on page 24 lists the possible
selections the user can choose for display. A different variable
can be displayed for each burner/boiler system.

Fig. 43. S7999D Home Page with Multiple Systems.
A fault in one of the burner/boiler systems will cause the Fault
Dialog box to pop up on the Home Page. The Fault Dialog box
will indicate which Boiler system has a fault and a fault
message. If the "Sound audio alarm for faults?" box (Display
Setup Page, General Tab) has been checked, an Alarm Bell
button will appear in the lower left hand corner. The S7999D
audio alarm will also be sounding. The Alarm Bell button can
be touched to silence the S7999D audio alarm.
No title is displayed on this page unless specified in "Display
Setup" page under the "Title" tab. The custom title entered by
the user is displayed on the page.
If you want to return from the components of a single system
back to the multiple system display, (all burner/boiler systems
on the Home page), touch the Return Back button in the top-
right corner of the page (see Fig. 44). This button is the same
icon that displays in the same position on all pages that have a
title.
