When in the MENU mode (as shown in Figure 8), pressing the LEFT ARROW key will
select the ALARM menus, the RIGHT ARROW key will select the VIEW menus and the
UP key the SET menus. The controller will go the next lower menu in the hierarchy, and
then other menus can be accessed by using the ARROW keys. Pressing the MENU key
from any menu screen will automatically return to the MENU mode as shown in Figure 8.
Another way to navigate through the menus is to press the MENU key when in the MENU
mode (as above). This will switch the controller to the SCROLL mode.
The controller will
automatically go to the first screen as shown below (the upper-left menu on the menu matrix
shown in Table 25 on page 40). From there, the four ARROW keys can be used to scroll
up, down, or across to any other menu.

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.

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
screen. 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. When the change has been made, press the ENTER key to enter it.
Nothing is changed until the ENTER key is pressed.
For example, to change the chilled water setpoint:
1. Press MENU key to go to the MENU mode (see Figure 8).
2. Press SET (the UP Key) to go to the setpoint menus.
3. Press UNIT SPs (the Right key) to go to setpoints associated with unit operation.
4. Press the DOWN key to scroll down through the setpoint menus to the third menu which
