The Unit Controller Operation
Figure 9, Unit Controller
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 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 case 3. 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” the currently displayed line. The selected line is highlighted.
Each line on a page can contain status only information or include changeable data fields
(setpoints). When a line contains status only information and the cursor is on that line,
all but the value field of that line is highlighted, meaning the text is white with a black
box around it. When the line contains a changeable value and the cursor is at that line,
the entire line is highlighted.
