Fig. 8. Lockout page
For pages other than Home and Lockout a
smaller font size is used to display the text
and pages have a format like the one shown
in Fig. 9.
Fig. 9. Page structure
The top line of the page is a title that
describes the context or purpose of the
page (see Fig. 9).The bottom line of the
page is a navigation bar which indicates
the more important button actions that can
be performed for the current input focus
(see Fig. 10). The middle or main body
of the page contains the lines that show
information or allow for user input. Up to 5
lines of text may be displayed in the main
body. Solid lines separate the title and
navigation bar from the main body.
INPUT FOCUS
Fig. 10. Input focus
An item on a page that has input focus
is usually highlighted with an inverse
look (black text on white background) to
distinguish it from the rest of the page.
The arrow buttons move the input focus
to another selectable item if another one
exists on the page (some pages may only
have a single focus item).
For pages that allow user input (see Fig.
10) the input value is edited on the page
and then is acknowledged or confirmed at
another tab position on the page ("Yes" tab
in the above example). This confirmation
action permits the user to cancel the editing
and not commit to the change or to accept
the edited value.

The Home page is the main status page
DETAIL
that displays primary status of the burner
control operation (see Fig. 11). This page is
intended to be the primary one displayed
most often when the user is not specifically
looking for other information or configuring
the display. The following information is
displayed by default:
• Burner control sequence or lockout state
• Flame signal strength
TITLE BAR
• Total cycles count
MAIN
• Total run-time hours count
BODY
• Annunciator connection status
NAVIGATION
• Remote command status
BAR
The burner control sequence state may
be displayed in one or two lines due to the
length of the text. In case of two lines the
remaining lines are pushed down to make
room for the second line.
This page also permits navigation to the
following pages:
• Lockout message (when burner control is
in a lockout condition)
• Fault history
• Burner control diagnostic status
• Annunciator diagnostic status (when
annunciator is connected)
• Burner control commissioning
(supported models only)
• Display menu
