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.

To change some parameters, a password is required.
The control system includes three levels of password
protection:
OEM Password Setup and parameter changes
available only to the factory.
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.")
User Level (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.

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.
