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 set point 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 set point 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.
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 screen
which contains Cool LWT=XX.X°F.
5. Press the ENTER key to move the cursor down from the top line to the second line in order to
make the change. If a password is not active, the control will automatically go to the Set
PASSWORD screen
6. Use the ARROW keys (now in the edit mode as shown above) to change the setting.
7. When the desired value is achieved, press ENTER to enter it and also move the cursor down.
At this point, the following actions can be taken:
1. Change another setpoint in this menu by scrolling to it with the ENTER key.
2. Using the ENTER key, scroll to the first line in the menu. From there the ARROW keys can
be used to scroll to different menus.
During edit mode, the display will show a two-character wide menu pane on the right as shown
below. They stand for; Default, Cancel, (+) Increase, (-) Decrease
