MENU Key
The MENU key is used to switch between the shortcut method (known as the MENU mode
and as shown in Figure 15) and scrolling method (known as the SCROLL mode). The
MENU mode is the shortcut to specific groups of menus used for checking ALARMS, for
VIEWING information, or to SET setpoint values. The SCROLL mode allows the user to
move about the matrix (from one menu to another, one at a time) by using the four
ARROW keys. A typical menu screen is shown in Figure 16.
Pressing the MENU key from any menu screen will automatically return you to the MENU
mode as shown in Figure 15.

Menu Screens
Various menus are shown in the controller display. Each menu screen shows specific
information; in some cases menus are used only to
view
the status of the unit, in some cases
they are used for checking and clearing
alarms
, and in some case they are used to
set
setpoint values.
The menus are arranged in a matrix of screens across a top horizontal row. Some of these
top-level screens have sub-screens located under them. The general content of each screen
and its location in the matrix are shown in Figure 17. A detailed description of each menu
begins on page 51.
The ARROW keys on the controller are used to navigate through the menus. The keys are
also used to change numerical setpoint values contained in certain menus.
Changing Setpoints
Pressing the ENTER key changes the function of the ARROW keys to the editing function
as shown below:
LEFT key
Default, changes a value to the factory-set default value.
RIGHT key Cancel, cancels any change made to a value and returns to the original setting.
UP key
Increment, increases the value of the setting
DOWN key Decrement, decreases the value of a setting.
These four edit functions are indicated by one-character abbreviation on the right side of
the display (this mode is entered by pressing the ENTER key).
Most menus containing setpoint values have several different setpoints shown on one menu.
When in a setpoint menu, the ENTER key is used to proceed from the top line to the second
line and on downward. The cursor will blink at the entry point for making a change. The
ARROW keys (now in the edit mode) are used to change the setpoint as described above.
