2. If the dialog box begins with the word “ENTER”,
use the numeric keys to enter the desired value.
Leading zeroes are not necessary. If a decimal point
is necessary, press the ‘•’ key (i.e. 45.0).
Pressing the ▲ key, sets the entry value to the default
for that setpoint. Pressing the ▼ key, clears the pres -
ent entry. The ◄ key is a backspace key and causes
the entry point to move back one space.
If the dialog box begins with “SELECT”, use the
◄ and ► keys to select the desired value.
If the previously defined setpoint is desired, press
the ‘X’ (Cancel) key to dismiss the dialog box.
3. Press the ‘

’ (Enter) key.
If the value is within range, it is accepted and the
dialog box disappears. The chiller will begin to op-
erate based on the new programmed value. If out of
range, the value will not be accepted and the user is
prompted to try again.
Manual Controls
Some keys are used to perform manual control func-
tions. These may involve manual control of items such
as the pre-rotation vanes, variable orifice or oil pump
speed. Other keys in this category are used to initiate/
terminate processes such as calibrations or reports.
Free Cursor
On screens containing many setpoints, a specific “soft”
key may not be assigned to each setpoint value. A soft
key will be assigned to enable the cursor arrow keys
below the numeric keypad which are used to “highlight”
the desired setpoint field. At this point, the ‘

’ key is
pressed to bring up a dialog prompting the user to enter
a new setpoint value. The ‘X’ key cancels cursor mode.
(See the Schedule Screen for an example.)
NaVigatioN
In order to maximize the amount of values which the
panel can display to the user, and in order to place those
values in context, multiple screens have been designed to
describe the chiller operation. In order to move from one
screen to the next, navigation keys have been defined.
These keys allow the user to either move “forward” to
a sub-screen of the present screen, or move “backward”
to the previous screen. Except for the Home Screen
display, the upper-right “soft” key will always return
the user to the Home Screen. Navigating with “soft”
keys is as simple as pressing the key next to the label
containing the name of the desired screen. The system
will immediately refresh the display with the graphics
for that screen. Following is a layout of all the screens
and how they are connected.
