Sometimes a screen is used to present a list, and often
the list is too long to present on a single screen view. To
see the rest of the list, pull down on the bar on the right
side of the screen, or use the up- and down-arrows.
To make a change, or to get more information about one
of the items on the list, press on the line for that item.

Login (required for some parameters)
To change some parameters, a Login (password) is
required. The control system includes three levels of
password protection:
OEM Factory Password Setup and parameter
changes Available only to the factory.
Login Installer Password
Setup and parameter changes made
when the system is installed, and some
diagnostic and troubleshooting functions.
The installer level password is “lnt” (lower
case “LNT.”) See Menu 3
User (no password required)
Non-critical adjustments and functions,
including adjusting the Central Heat and
Domestic Hot Water setpoints, monitoring
the input and output variables, reading
parameters from the controller, and reading
the error log
(For some special safety-related functions, besides
entering the correct password, the system will ask you
to go through an additional “verification” process. For
more information, see the section on “Configuration.”)
When a password is necessary, the system will present
the keyboard screen. See Menu 3.
Menu 3.
Keyboard Screen
The passwords used by this system are “case
sensitive” – it matters whether a letter in the password
is capitalized or not. Pressing the Shift key toggles
between capital and lower case letters.
“BS” stands for “Back Space,” and also works as a
Delete key.
Anyone can view
all of the parameters. 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
