On System applications, each Burner Control System is
represented on the Home page by an icon and name. Pressing
the icon allows the user to zoom in on that boiler and see its
specic details. These details are provided on a new page, which
can include additional buttons that display additional detail and
operation information, which itself leads to other pages. The
pages are traversed in a tree structure method, as shown in
Figure 53 on Page 52.
The Control System icons will appear in one of four colors
indicating the boiler status.
• Blue: Normal operation
• Red: Lockout condition
• Gray: Standby mode (burner switch off)
• Gray and crossed out: communication error
(disconnected or powered off)
• Yellow: Preparing for Start-up.
Up to 8 Systems can be displayed on the Home page. The name
of each boiler is displayed next to the Control System icon button.
When Lead Lag is enabled, the system header temperature and
ring rate are displayed for each System. When the burner is in
standby or not ring the ring rate is not displayed.
Note: The boiler name may be cut off on the Home page when
all icons are present.

allows the user to view status information on a system-wide
(that is, multiple boiler) basis. The user can choose which status
information to compare from the Burner Controls in the system.
