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.
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.
Common OI Display Page Symbols
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.
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.
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.
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 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.
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.
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
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
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.
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.
•
•
•
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.
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.
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 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.
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.
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.
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.

WARNING
Improper configuration can cause fuel buildup and
explosion.
Improper user operation may result in PROPERTY
LOSS, PHYSICAL INJURY or DEATH.
Explosion Hazard.
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.
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
Like operating parameters, safety parameters can be viewed
without the need to enter a password.
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.
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).
The changed setting is reflected on the screen and sent to the
control when the OK button is pressed.
NOTE: When the installer proceeds with the safety parameter
configuration, the control unlocks the safety parame-
ters 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.
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).

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.

of history to view. The user can also silence an audible alarm
generated by the control during a lockout or alert by alarm
condition.
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.
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 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 con-
trols’ 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

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
more information about this status.
(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.
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.
Fig. 34. System refresh.
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. 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.

The MAC (Media Access Control) address is a hardware
address that uniquely identifies the S7999B on the network.
This information is likely only of interest to the network
administrator.
ADVANCED SETUP
Pressing the ADVANCED SETUP button on the Setup page
displays more options that can be set by the user (Fig. 104).
The IP (Internet Protocol) address is the address that the
S7999B has been assigned by the DHCP server in the local
network to use for others to access the S7999B. This address
is necessary for the remote user to identify the S7999B in an
FTP (File Transfer Protocol) application for transferring trend
analysis information. Like the MAC address, it is displayed for
informational purposes for the network administrator.
If the IP address has a private network designation (192.x.x.x),
remote access from outside the local network may not be
possible. Contact the network administrator for assistance in
this case. If the IP address is 255.255.255.255, then no IP
assignment has been made, and there is no connection to the
network. This possibility could be due to no physical
connection to an Ethernet network, or there is no DHCP server
present on the Ethernet network. Check with the network
administrator for assistance.
The Gateway IP address is displayed for informational
purposes for the network administrator. The gateway node
provides remote access for devices located off of the local
network to the S7999B.
Fig. 104. Advanced Setup.
The Enable Network checkbox specifies that the Ethernet
interface is on or not when the S7999B is powered up. The
selection must be saved to permanent storage (flash) with the
Save button for it take effect at boot time. This checkbox
should normally be disabled, and enabled when Ethernet
access to the S7999B is necessary. This interface must also
be enabled for the Software Server Connectivity check to
function properly (the Check button). If the Ethernet interface is
disabled, the check procedure fails.
Ethernet Settings (S7999B Only)
Ethernet Settings is used to enable Ethernet communications
for remote diagnostics, file transfers, and remote support, and
is not typically enabled (Fig. 105). This feature should remain
disabled unless directed to do so for remote troubleshooting.
Once the feature is enabled, the S7999B must be reset to start
it at power-up. The Ethernet interface can also be used to
transfer profile curve files to/from the S7999B over a local
intranet or the Internet.

S7999B, S7999C SOLA LOCAL OPERATOR INTERFACE
The S7999B must be assigned an IP address by a DHCP
server for it to operate on the local network, so the Use DHCP
box should be checked. However, because the S7999B
requires this feature, it ignores the checkbox and always
regards it as checked. The checkbox is included for future
purposes when dynamic IP addressing isn’t required.
The status variable with the largest range (minimum to
maximum) is used as the Y-axis range in the graph.
As the status variables are selected they are listed in a trend
variables list box. The user chooses the status variables from a
drop down menu and then presses the Add button to add each
status variable to the trend variable list. See Fig. 108. After all
status variables have been selected press the Show button to
view the trend analysis graph.
Trend Analysis Page (S7999B Only)
Trend analysis of R7910 or R7911 status data can be viewed
on the S7999B. A graph displays a historical view of R7910 or
R7911 status data over varying time periods.
A 2-dimensional graph with status data values shown on the Y
axis over time specified on the X axis is displayed. Status for
the most recent time is represented on the left side of the
graph with older status running towards the right side of the
graph.
Fig. 108. Trend analysis menu page.
Each status variable displayed in the trend analysis is
represented by a different colored line, as follows:
1. First status variable = green
2. Second status variable = yellow
3. Third status variable = red
4. Fourth status variable = blue
Fig. 106. Trend analysis page.
No more than two different measurement units (such as
degrees), are allowed for the status variables selected in the
trend analysis graph. Attempts to add a status variable with a
third measurement unit are rejected.
Up to 4 R7910 or R7911 status variables can be viewed at the
same time on one trend analysis graph. Select the status
variables for the graph on the menu page (see Fig. 107). This
menu displays when the Trend Analysis button is selected on
the R7910 or R7911 status page.
A second Y axis is displayed on the right side of the graph to
represent the scale for the second measurement unit. This can
result in minor clipping of the curves on the right side, as
shown in Fig. 109 and 110.

the graph so the Y axis depicts different degrees of detail for
the data range. The viewing window can be moved up and
down the graph to see the complete range when zoomed in.
The smallest measurement interval is a single whole digit (no
fractional precision) when the entire range exceeds 10 units,
e.g., 20–30 degrees.
Pressing the Stop button will pause trend data updates of the
graph. The graph “freezes” the view when stopped. However,
trend data sampling from the R7910 or R7911 continues
regardless whether the graph update is stopped or not.
Restarting the updates causes the graph to be refreshed with
the latest data samples.
Pressing the Clear button will clear the trend sample data for
an R7910 or R7911. All trend data for the R7910 or R7911 is
cleared including status variables that are not included in the
graph. The user is asked to confirm this action before
proceeding.
Fig. 109. Trend analysis page with firing rate.
NOTE: For system trend analysis graphs the Clear button
isn’t present, so no status variables can be cleared.
A snapshot of the trend analysis graph can be taken and saved
to the S7999B. The user is asked to confirm the save before it
occurs.
NOTE: While this snapshot is saved, trend data sampling for
all R7910s or R7911s is temporarily halted. Gaps or
static level values occur in the trend data as a result.
The date and time that the snapshot is taken is stored with the
snapshot. Only the status variables displayed in the graph are
stored in the snapshot. All raw sample data for the status
variables are stored so that any sample rate can be viewed
offline.
Sample data stored in snapshot is either the real-time status at
the time that the Save button is pressed or it is the sample data
at the time that the graph is stopped.
Special case trend analysis graphs for PID tuning can be
viewed for CH, DHW, and Lead Lag demands.
Fig. 110. Trend analysis page with demand source.
If any of the status variables has degrees as a unit of
measurement, degrees is used for the main Y axis (on the left
of the graph). The status variables selected are saved and are
displayed by default when the trend analysis menu page is first
displayed. Status data is updated on the graph with new status
at the same rate as the sample time period selected. The
current sample time period is displayed in a button on the page
(in Fig. 109 and 110, the button is “Seconds”).
Status older than the sample time period is dropped from the
right end of the curve as newer status appears on the left end
of the curve.
Trend data can be viewed in one-second (most recent 60
second time period), 15-second (most recent 15-minute time
period), and hour (most recent 24 hour time period) intervals.
NOTE: Full graphs require that the S7999B has been moni-
toring the R7910 or R7911 for the complete time
period. Partial graphs display if this is not the case.

invoke sampling.
NOTE: Sample data is collected and stored in the S7999B. The
R7910 or R7911 don’t collect any historical data for trending
purposes. For this reason any S7999B reset causes all
R7910 or R7911 sampling to start over with no data.
