However, to
change
most of the parameters,
you will need a password.
At the bottom of the screen, the system
indicates that you need to enter a password.
Menu 4. Login Required
The screen used to Login is similar to the
Keyboard screen.
It may be difficult for some operators to press
the keys on this screen. In this case, use the
back of a plastic pen, or a stylus, or a pencil
eraser. (Do not use sharp metal tools – these
may damage the plastic surface of the screen.)
Each time you press a key, the system will
respond with a beep. If you are entering a
password, an asterisk (*) will appear for each
character you enter. The beeps and asterisks
will help you enter the correct number of
characters for your password.
When changing a numerical value, the system
presents a numerical entry screen, as shown
below.

Verification Process for Safety-
Related Parameters
The verification process allows the user
to confirm that all the changes made are
correct and that there have not been any
inadvertent changes made.
1. When you start to change a parameter
that is related to safety, the system will
present a warning which looks like this:
Menu 6. Parameter Safety Warning
WARNING
Changing safety parameters should only be
conducted by experienced, licensed boiler
operators and mechanics. Hazardous burner
conditions can happen with improper operations
that may result in PROPERTY LOSS,
PHYSICAL INJURY, or DEATH.
Press OK to continue. The system will
ask you to login before you make a
change. (For more information on logging
in, see Section 8.2.)
2. If you make a change in any group that
could affect the safe operation of the unit,
the control system will ask you to “verify”
the change before it is accepted.
3. Once all parameters have been changed,
return to the configure menu. In the lower
right hand corner of the screen you will
see ‘VERIFY’ Press VERIFY, then press
BEGIN to start verification.
Notes –
• Once you change one of these safety-related
parameters, you
must
finish the verification
process for the group that includes the parameter,
or the control system will not let the boiler
operate
. You can wait to do the verification until
you have changed parameters in other groups, but
before you return the boiler to service, you must
complete the verification process for all groups
that have been changed.
