Keyboard Functions
The keyboard contains six push-buttons that are used to navigate on each page and between pages on the display
module (see Fig. 6). These buttons generally have the following functions:
• Up arrow - move up on a page or increment a value for an input control
• Down arrow - move down on a page or decrement a value for an input control
• Left arrow - move to the left on a page (tab left) or go to a previous page
• Right arrow - move to the right on a page (tab right) or go to the next page when applicable
• OK - approve/accept the highlighted item or go to the next page when applicable
• Home - go to the Home (Main Status) page
These buttons are acted on when they are pressed and released. In some cases a button can be pressed and held, i.e., not
released, for repeated execution of the button (arrow buttons). Buttons are active on some pages only when the action for
the button makes sense for the position of the input focus on the page. If the input focus doesn't make sense for the
button action, selecting the button is ignored.

When the burner control module is in a Lockout condition the "Home" button navigates to the Lockout page instead of the
Home page to display the lockout.
Page Structure
The Home and Lockout pages display text using a larger font size than all other pages so that information on them can be
more easily viewed from distances farther away from the display module (see Fig. 7 and Fig. 8).
Up to 4 lines of text are displayed at a time on the page. When the page has more than 4 lines of text to display a scroll bar
is present on the right-hand side of the page to indicate this situation. The "Up arrow" and "Down arrow" buttons are used
to scroll up and down the lines of the page. Each line is highlighted with a white background to indicate that it currently
has input focus for any button actions. The scroll bar adjusts to give a relative position of the current view with respect to
all lines that the page can display.
