PREFACE
This User Guide is intended to provide a general overview of
the S7999B or S7999C Operator Interface (OI) Displays. The
general overview goes to page 20 and the actual configuration
begins on page 20.
It is intended to guide you through the features and operation
of the OI Display as you interface with the R7910A or R7911
Sola control and establish the Parameter points of the system.
Note that this sheet shows all parameters. The actual product
may have parameters made invisible or Read Only by
Honeywell as they may not apply to the product.
Use the Product Data Sheet for the Sola Controls (form 65-
0303) as a guide and explanation of the parameters that are
being programmed.
SOFTWARE UPGRADE
S7999B Only
You can download new software for the OI Display through
the Internet. Downloading software should only be done when
recommended by Honeywell. This feature is intended to
permit field upgrades for bug fixes and to install new features.
Requirements for downloading new software:
• Ethernet connection for Internet access (RJ45 male
connector). Carefully insert the RJ45 connector into the
Ethernet jack in the lower right corner on the back of the
display to ensure no damage to the jack.
• Dynamic IP addressing (from DHCP server).
IMPORTANT
If these requirements can’t be met at the location of
the OI Display, this procedure should not be done or
the OI Display should be moved to a location where
these requirements can be met. Failure to satisfy
these requirements can result in the OI Display
becoming inoperable when the upgrade steps are
followed.
The above requirements can be checked prior to execution of
the software upgrade procedure on the Ethernet Setup page
(see Advanced Setup section). On the Ethernet Setup page a
connectivity check can be performed to validate whether
access to the Honeywell server is possible.
The OI Display must be reset to initiate the download
procedure. Initial boot procedure of the device permits the
user to enter into Advanced Startup options within the first five
seconds after power up.
Follow these steps:
1. Select the Advanced Startup Options button. A Warning
message is displayed. If you don’t want to proceed with
the software upgrade, you can cancel the procedure at
this time.
2. Select OK to proceed.
3. Select the “Force Application Update” checkbox.
4. Deselect the “Use Existing Application” checkbox.
5. Select the Continue button.

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).
65-0303—0512
• History: used to view burner control history (see “History
Button” on page 16 for more details).
• ?: used to expand the pump status information.
• Modulation: used to toggle between status displays: pump,
setpoints, and modulation.
Fig. 14. Summary status page (Hydronic Control shown).
Configure Button
Pressing the Configure button (bottom left) on the Status page
opens the Configuration page. The Configuration page shown
in Fig. 15 is for the S7999C OI display.
S7999B, S7999C SOLA LOCAL OPERATOR INTERFACE
Fig. 15. Configuration menu page. Shown is the S7999C on
a Hydronic Control.
No specific order for configuration is required. All parameters
are enabled for editing, though some may not be applicable
(e.g., a configuration parameter may disable a control feature).
Selecting a parameter group from the menu displays
parameters exclusively applicable for the functional group on
the page (see Fig. 16). These parameters can be edited, and
when the user is finished, control returns back to the
configuration menu page.
The S7999B Configuration page does not have a “Display
Setup” button.
Display Setup (S7999C only): Pressing the Display Setup
button displays miscellaneous S7999C OI Display setup and
diagnostic functions (See page 47 for options). (The same
function as the 1234 Setup on the S7999B home page.)
The configuration page allows the user to view and set
parameters that define how the connected R7910A functions in
the hydronic heating system or the R7911 steam heating
system.
The configuration page contains a menu of parameters
grouped into functional areas that the user selects for
configuration (see Fig. 16). See Table 61 on page 53 for all
parameters available for configuration. If some parameters are
not visible, they have been made invisible by Honeywell.
Fig. 16. Sample configuration page for the S7999B
Hydronic Control.
Each parameter is displayed in its group. If there are more
parameters than will fit on the screen, a vertical scroll bar
allows the user to scroll up and down to view all parameters.
The parameter name is displayed on the left and the current
setting is displayed in the text box on the right.
Configuration Password
Some parameters require a valid configuration password be
entered by the user before the parameter can be changed. The
password need only be entered once while the user remains
on the configuration pages. Leaving the configuration pages
ends the scope of the password.

S7999B, S7999C SOLA LOCAL OPERATOR INTERFACE
WARNING
Three levels of access to Sola Control parameters are
permitted. Each access level has defined rights when
interfacing with configuration and status parameters within the
controls.
• End user: The end user can read or view the control
parameters and be allowed to change some operating
parameters, CH setpoint as an example.
• Installer: The installer can read all control parameters and
change Honeywell's allowed parameters. This access level
is used to customize the control for a particular installation.
• OEM: The OEM can read and change all parameters,
change sensor limits and burner control safety parameters.
Different passwords exist in the Sola Control for each access
level. The end user level requires no password, but the
installer and OEM levels have unique passwords defined for
them.
The installer and OEM passwords can be changed in the Sola
Control after logging in with the current password. When the
password is changed, it is saved for all future logins.
NOTE: For the S7999B System OI display, each boiler in a
multi-boiler configuration has its own set of installer
and OEM passwords. To avoid user confusion, the
passwords should be changed to the same password
in each control, but there is no requirement to do so.
Make sure to record your password.
The user is notified that a new password is needed to change a
parameter (or until a password is entered successfully)—see
Fig. 17. The user can continue viewing the configuration
parameters regardless of whether a password is entered
successfully.
The user is not required to enter a configuration password for a
parameter that has a lower access level than the access level
achieved by an earlier password entry for any configuration
group (as long as the user stays in the configuration pages).
The user only needs to enter a password once until a
parameter that has a higher access level is selected.
Keyboard
Some pages request user entry of characters. When this type
of input is required, a keyboard page appears, as shown in Fig.
18. The text box at the top of the screen displays the current
(or default) setting of the user input. The user can add to this
text, clear it, or change it.
The Shift key on the left side of the screen shifts between
upper and lowercase characters. Pressing the Shift key
toggles the keyboard from one mode to the other (continuous
pressing of the Shift button is not required). The OK button
should be pressed when the user is done entering the text
input. The Cancel button on the bottom of the screen allows
the user to ignore any text changes that have been made and
keep the original text value. Pressing the OK or Cancel buttons
returns the user to the page displayed prior to the keyboard
page.
Login
Pressing the Login button allows entering the password from a
keyboard as shown in Fig. 18. After the password is entered,
the OK button is selected. The Cancel button aborts the
password login.
Fig. 17. Login required. (S7999B Hydronic Control Shown.)
The Sola Controls maintain a password time-out that limits the
scope of the password entry. Once a password is successfully
entered, the control starts an internal timer that expires after 10
minutes of inactivity. After the timer expires, the user is
required to re-enter a password before a parameter can be
changed.
65-0303—0514

Explosion Hazard.
Improper configuration can cause fuel buildup and
explosion.
Improper user operation may result in PROPERTY
LOSS, PHYSICAL INJURY or DEATH.
Using the OI Displays to change parameters must be
attempted by only experienced and/or licensed burner/boiler operators and mechanics.
S7999B, S7999C SOLA LOCAL OPERATOR INTERFACE
Change Parameter Settings
Change parameter settings by selecting the parameter on the
page. A dialog box displays for the parameter with controls
allowing the user to change the value (see Fig. 19). After
changing the setting to a new value, press the OK button.
Pressing the Cancel button leaves the parameter unchanged.
The changed setting is reflected on the screen and sent to the
control when the OK button is pressed.
Like operating parameters, safety parameters can be viewed
without the need to enter a password.
Safety parameter blocks that have been changed require
verification. The verification steps do not have to be completed
immediately; the installer can move between and change
parameter groups before the verification is done. A Verify
button is enabled that allows the installer to conduct verification
sessions (the example of the Verify button in Fig. 15 is not yet
enabled because the installer hasn’t logged in).
NOTE: When the installer proceeds with the safety parameter
configuration, the control unlocks the safety parameters in this group and marks them unusable. Failure to
complete the entire safety configuration procedure
leaves the control in an un-runnable state (lockout 2).
All safety configuration parameters in the group should have
the same access level. If this condition isn’t so, the user is
asked to enter another password when a higher access level is
needed.
Successful login is noted by the lock icon, which changes to
“unlocked” on the page. The installer may begin to change
safety parameters (or any other parameters) at that time. (See
Fig. 21.) If the Sola Control is in an unconfigured (or new)
state, then this warning doesn’t appear. All parameters that
need changes should be changed during the login.
Fig. 19. Change configuration parameter page example of
a Hydronic Control.
Verify
Pressing the Verify button displays safety configuration
parameters for an additional verification step to commit the
changes.
Safety parameters are grouped into blocks that include only
safety parameters, not a mixture of safety data and non-safety
data. All parameters within the safety group undergo a
verification process. A safety parameter group is identified on
the display to indicate when the configuration parameters are
safety-related. Each safety parameter group is verified one at a
time until all have been verified. See Fig. 20.
Fig. 21. Edit safety data.
If the safety configuration session is terminated after it has
started (in the Edit or Verify stages), the Sola Control is left in
an unconfigured (unrunnable) state.
The installer can terminate the session by pressing the Menu
button or by attempting to leave the Verification page with the
Home or Back buttons (top-left and -right screen corners,
respectively). However, leaving the session at this point leaves
the control in an unrunnable state and confirms whether the
installer still wants to do so.
Fig. 20. Safety verification.
The settings of all parameters in each safety block must be
verified to save them in the control.
When the installer is done changing safety parameters,
pressing the Verify button on the configuration screen begins
the Verification process. The settings for all safety parameters
in each changed block are presented and Verified by the
installer (see Fig. 22).
1565-0303—05
S7999B, S7999C SOLA LOCAL OPERATOR INTERFACE
Fig. 22. Safety parameter confirmation.
Press the Yes button to confirm each safety parameter block. If
the No button is selected, the safety parameter block remains
unconfirmed and the Configuration menu page is displayed.
The control remains in an unconfigured state in this case.
After all safety parameter blocks have been confirmed, the
installer is asked to press and hold the Reset button on the
Sola Control to complete the safety verification session (see
Fig. 23).
Safety lockouts are indicated on each configuration page as an
alarm bell symbol. At the home (for S7999C) or status page
(for S7999B), the History button turns red. If the S7999B is
displaying the system status icons, the control in alarm will turn
red.
The lockout history can be displayed by pressing on the
History button. The state information about each lockout is
displayed along with the date/time that the lockout occurred
(see Table 3). Current date/time stamp is a display setup
feature.
NOTE: In the event of a power interruption, the date/time
must be reset. The OI Display does NOT have a
backup means.

above Reset dialog box automatically closes when this step is
completed.
If this step is not performed, the control remains in a safety
lockout state until the installer resolves the unverified safety
parameters.
Fault/Alarm Handling
Each Sola Control reports to the OI display when a safety
lockout or an Alert occurs.
65-0303—0516
An alert log can be displayed for each control by pressing the
Alert button on the bottom of the history status page. A
description of the alert is displayed along with the time when
the alert occurred (see Table 4).

History Button
The History button on the Home page serves not only as a
button, but also displays Sola Control lockouts, holds, and
alerts as they occur. The History button can be selected at any
time, regardless of which type of information is displayed, to
view history information. Pressing the History button displays a
dialog box (see Fig. 24) that allows the user to select the type
S7999B, S7999C SOLA LOCAL OPERATOR INTERFACE
of history to view. The user can also silence an audible alarm
generated by the control during a lockout or alert by alarm
condition.
This History dialog box provides an exploded view of the status
information displayed in the History button (the font is larger).
One of the four buttons (OK, Lockouts, Alerts, or Silence) can
be selected. If none of these buttons are selected the dialog
box closes after 30 seconds.
The date and time that each fault occurred is displayed in the
lockout history. The lockout timestamp displays in both the
lockout summary and detail information.
The Sola Control does not maintain date or time of day
information. The date and time stamp is assigned by the OI
display. When the OI display first obtains the lockout and alert
history from the control (during the display data
synchronization), no timestamps are assigned since the times
that the lockouts occurred are unknown. All new lockouts that
occur after the synchronization are assigned timestamps.
NOTE: The system time can be set in the OI display to
ensure that correct timestamps are given to the controls’ lockouts and alerts. Power interruptions will
require the time to be reset as the display DOES NOT
have a time backup means.
The Clear Lockout button allows the user to acknowledge and
clear (reset) the lockout when in lockout state, much the same
as pressing the reset button on the front of the Sola Control.
The user can toggle between displaying the controls’ lockout
history and alert log by pressing the Alerts or Lockouts button
on the bottom of the pages.
Fig. 24. Hydronic history example shown—exploded view.
Two types of historical data can be displayed on the history
page: lockout history and alert log.
The entire 15 fault code history is displayed in a scrollable list
with the most recent fault displayed first followed by the next
most recent fault. Summary information is displayed for each
fault entry, including the burner cycle count, fault code, and
fault number with description. Detailed information for a
specific fault entry that also includes burner control sequence
state, burner run-time hours, annunciation status, etc., is
viewed by selecting (touching the History line) the lockout entry
in the list (see “Fault/Alarm Handling” on page 16 for details).
Fig. 26. Alert log example shown.
To see additional detail about a lockout or alert, touching on the
lockout or alert in the list expands the view of that lockout or
alert, as shown in Fig. 27 and 28.

Operation Button
The operation button displays the SOLA Control running
operation, including setpoint and firing rate values. From this
page the user can change setpoints, manually control the
boiler’s firing rate, manually turn pumps on, view annunciation
information, and switch between hydronic heating loops
(Central Heat and Domestic Hot Water), as shown in Fig. 22. If
a password is required to change any of the settings on this
page, the user can press the Login button to enter the
password.

Diagnostics Button
The Diagnostics button displays analog and digital I/O status of
the SOLA Control. A snapshot of the diagnostic status is
displayed and updated once per second as it changes in the
control. See “R7910A or R7911 Diagnostics” on page 44 for
more information about this status.
The digital I/O data is displayed as LEDs that are either on
(green) or off (red) (See Fig. 23). Not all digital I/O can be
displayed at the same time on the page, so a horizontal scroll
bar is used to move the view left and right to show all digital
I/O data.
System Configuration
(S7999B OI DisplayOnly)
The OI Display has some functions related to general
configuration for the control in the end user installation.
Pressing the Display Refresh button invokes a search
procedure (see Fig. 34). A new R7910A Hydronic Control or
R7911 Steam Control is identified by “Unknown” status next to
its name in the boiler system list (see Fig. 35). “Unknown”
indicates that configuration data has not been retrieved from
the control yet.
Fig. 32. Diagnostic page (digital I/O).
The control analog I/O can also be viewed on the OI Display. A
snapshot of the diagnostic status is displayed and updated as
it changes in the control.
The analog I/O data is displayed as bar charts with I/O level
represented in the I/O range (see Figure 24.) Analog I/O that is
not enabled for the installation displays a blank I/O level. Not
all analog I/O can be displayed at the same time on the page,
so a horizontal scroll bar is used to move the view left and right
to show all analog I/O status.
Fig. 34. System refresh.
Fig. 35. System configuration page.
The control connected to the Modbus network is indicated to
the user after the search procedure has concluded.
Once the control is located it must be synchronized with the OI
Display before it can be displayed. New controls are not
displayed on the Home page until this synchronization (see
below) is performed.
Fig. 33. Diagnostics page (analog I/O).
System Synchronization
(S7999B OI Display Only)
The user can manually synchronize configuration data from the
connected controls at any time.
1965-0303—05
S7999B, S7999C SOLA LOCAL OPERATOR INTERFACE
WARNING
A new control is visible when configuration and status data is
gathered from it. This collection procedure takes a few
minutes. The control is marked as “Unknown” when no
configuration information exists. Normally, control configuration
data collection only needs to be performed when the control is
initially installed. However, a re synchronization is necessary
after the OI Display is reset. See Fig. 36.
The user presses the Synchronize button to begin
synchronization with the control. See Fig. 36.
Fig. 36. System synchronization.
Status of the synchronization is reflected in the dialog box. The
synchronization can be aborted by selecting the Cancel button.
