The keypad/display consists of a 5-line by 22-character
display, three buttons (keys) and a "push and roll" navigation
wheel. There is an Alarm Button, Menu (Home) Button and a
Back Button. The wheel is used to navigate between lines on
a screen (page) and to increase and decrease changeable
values when editing. Pushing the wheel acts as an Enter
Button and will jump from a link to the next set of parameters.

Generally, each line on the display contains a menu title, a
parameter (such as a value or a setpoint), or a link (which will
have an arrow in the right of the line) to a further menu.
The first line visible on each display includes the menu title and
the line number to which the cursor is currently "pointing." In
the above screen, Temperature is highlighted.
The left most position of the title line includes an "up" arrow ▲
to indicate there are lines (parameters) "above" the currently
displayed line; and/or a "down" arrow ▼ to indicate there are
lines (parameters) "below" the currently displayed items or an
"up/down" arrow • to indicate there are lines "above and below"

Or a line in a menu may be a link to further menus. This
is often referred to as a jump line, meaning pushing the
navigation wheel will cause a "jump" to a new menu. An arrow
(>) is displayed to the far right of the line to indicate it is a
"jump" line and the entire line is highlighted when the cursor is
on that line.
NOTE - Only menus and items that are applicable to the
specific unit configuration are displayed.
This manual includes information relative to the operator level
of parameters; data and setpoints necessary for the every
day operation of the chiller. There are more extensive menus
available for the use of service technicians.

also be accessed by pressing the Menu Button The navigating
wheel is the only navigating device necessary, although the
