Figure 16 Sample Configuration Page
These parameters can be edited, and when the
user is finished, control returns back to the
configuration menu page. 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.
2.2.7 CONFIGURATION PASSWORD
Any user can view the configuration parameters
(default mode). No access-level password is
required to view the parameters. A valid
configuration password for the parameter’s level
must be entered 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 entry. The user is
notified that a new password is needed upon the
first attempt to change a parameter (or until a
password is entered successfully). The user can
continue viewing the configuration parameters
regardless of whether a password is entered
successfully.
The boiler also maintains a password timeout
that limits the scope of the password entry.
Once a password is successfully entered the
boiler 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. 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.
The user enters the password from a keyboard
as shown in Figure 13. After the password is
entered, select the OK button. The Cancel
button aborts the password login.
WARNING:
Explosion Hazard.
Improper configuration can cause fuel
buildup and explosion. Improper user
operation may result in PROPERTY
LOSS, PHYSICAL INJURY or DEATH.
Changing parameters, must be
attempted by only experienced and/or
licensed burner / boiler operators and
mechanics.
Three levels of write access to boiler parameters
are permitted. Each access level has defined
rights when interfacing with configuration and
status parameters in the Boiler.
• End user: The lowest access rights (no
password login). The end user can, in most
cases, only read or view boiler parameters. In
some instances the end user can change boiler
parameters, e.g., change the CH, central heat,
setpoint.
• Installer: The next highest level. The installer
can read all boiler parameters and change most
boiler parameters. This access level is used to
customize the boiler for a particular installation.
The default installer password is ‘
bryan’.
• OEM: The highest access level. The OEM can
read and change all R7910 parameters, as well
as change sensor limits and burner control
safety parameters
.

Different passwords exist in the boiler for each
access level. The end user level requires no
password, but the installer and OEM levels have
unique passwords defined for them. The display
