Page Navigation - A.O. Smith 100 Series Service Handbook

On System applications, each Burner Control is represented on the Home page by an icon and name. Pressing the icon allows the
user to zoom in on that burner and see its specific 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 31 on Page 47.
The Control System icons will appear in one of four colors indicating the boiler/water heater status.
• Blue: Normal operation
• Red: Lockout condition
• Gray: Communication error (disconnected or powered off)
• Yellow: Holding mode
Up to 8 Systems can be displayed on the Home page. The name of each burner is displayed next to the Control System icon button.
When Lead Lag is enabled, the system header temperature and firing rate are displayed for each System. When the burner is in
standby or not firing the firing rate is not displayed.
Note: The boiler/water heater name may be cut off on the Home page when all icons are present.
The Home page also includes buttons for Lead Lag configuration when lead lag master and slave in the Burner control is enabled.
Pressing the Setup button on the Home page displays miscellaneous setup and diagnostic functions. It also contains the setup
configuration for BAS applications.
The "Control snapshot" button allows the user to dump the current status and/or configuration settings of any Burner controller into
a text document. The text document can be viewed on the display, saved to flash for later viewing, and can be written to a USB stick
for viewing on a PC or file transfer. Pressing the Burner control icon opens that control's status page. Go to "Configure" button to
continue.
