The Command Display provides a com mu ni ca tion interface with
the Excel 10 via a series of display screens. The front view of the
display screen shows the digital display with a cluster of arrow
keys on the lower left side. These directional arrow keys move
the cursor in the direction of the arrow.
On the lower right side is a back key which moves the display to
the previous screen and a select key which high lights a field in
the display.
There are also four softkeys along the right side of the display. A
notation on the specific screen defines the function of each of
these keys. The softkeys may be defined as configure, change,
save, cancel, + to increase a value or - to decrease a value on the
screen.
PASSWORD FUNCTION
On initial operation of the Intelli-Fin the owner may enter three
levels of password with the Command Display to limit access to
the changeable op er at ing parameters in the Excel 10. Each
password is composed of a four digit number. As shipped from
the factory all passwords are zeros. The first level of password
allows access to the six changeable points accessible from the
Command Display. The second level of password allows access
to the configura tion settings of the Command Display. The third
level of password allows the password to be changed.
FIG. 55 Command Display Password Screen
The configure button also allows the user to access the password
function to enter a password in the Excel 10 from the Command
Display. Use of a password will limit the access to the
changeable points. When located at the password screen, move
the cursor to the first blank space (by using the left or right
buttons on the left side of the Command Display). Use the “+”
or “-” buttons on the right side of the Command Dis play to either
increase (+) or decrease (-) the number to the desired number.
Then use the left or right buttons to move the cursor to the next
space and repeat this procedure. Once the pass word has been
entered, push the “SAVE” button. Once a password number
sequence has been entered into the Command Display, they must
be correctly reentered to change any of the six adjustable points.
If an incorrect password sequence is entered, the pass word screen
will stay in place.
NOTE:
Once a password is correctly entered, it will not have to be
reentered unless five minutes of inactivity on the Command
Display has elapsed.
CONFIGURING THE
COMMAND DISPLAY
When the “CONFIGURE” button on the right side of the Command
Display is pressed, a password screen will appear. The user must
enter the appropriate password and press “SAVE” to access the
changeable screen. Pressing this but ton provides access to a
“setup” screen that allows the user to adjust such items as:

ACCESSING THE SIX
CHANGEABLE POINTS FROM
THE COMMAND DISPLAY
When the “CHANGE” button on the right side of the control is
pressed, a pass word screen will appear. The user must enter the
appropriate password and press “SAVE” to access the changeable
screen. The desired point to change must be highlighted by moving
the cur sor and then use the “+” or “-” buttons on the right side to
change the value to the desired value. Once the desired value is
reached, press the “SAVE” button and the new value will be saved
and the Command Display will return to the first screen of the 21
points for that boiler/water heater. The password must be entered
each time a user wants to change the settings of any of the six
changeable points. However, if you go to the screen again within
5 minutes of the last time, it will not require the password again. If
the screen is left in the changeable point screen for more than 5
minutes with no activity, it will automatically return to the first
screen of the 21 points for the boiler/water heater. Re-entry into this
changeable point screen will then require password access again.
