PAGE NAVIGATION

The Sola OI Displays present information and options in a
paged manner. Pages are displayed in a tree structure in which
the user navigates up and down to arrive at the desired
Function (see Fig. 8 for S7999B or Fig. 13 for S7999C). The
page descriptions are provided below so that you can
understand the purpose of each and view the selections,
parameters, and information that is available or required on
each.

Common OI Display Page Symbols

Most pages have a Home button in the top-left corner of
the screen and a Back button in the top-right corner of
the screen. The Home button returns the user to the Home
page and terminates any operation in progress. The Back
button returns the user to the previous page.
Two other icons may be noticed near the boiler name.
A bell will be displayed if the system is in Lockout that
reset will be required.
A padlock will be shown on screens that require a password
to change the parameter. An unlocked padlock indicates the
password has been entered to change the parameter.

Status or Home Page

A status (summary) page (Fig. 14) is displayed when the
S7999C display is connected. This status page appears on the
S7999B when the Sola control icon is pressed on the “Home”
page. The status page displays the current condition of the
burner control and displays some of the more important
configuration settings.
The boiler name associated with the burner control is
displayed in the title on the status page.
NOTE: When the burner control has no boiler name defined,
Modbus address is used to identify the boiler.
The initial status page displayed contains summary status
information as shown in Fig. 14. Any status information not
applicable for the installation is grayed/blanked out on the
screen.
Buttons on this screen include:
•Configure: used to configure the burner control (see
“Configure Button” on page 13 for more details).
•Operation: used to perform daily or frequent functions with
the burner control, such as setpoint adjustment, etc. See
“Operation Button” on page 18 for details.
•Diagnostic: used to view burner control diagnostic
information (see “Diagnostics Button” on page 19 for more
details).
•Details: used to view burner control detail status
information (see “Details” on page 38).
