GENERAL

The Entry keys allow the user to change numerical val-
ues programmed in as chiller setpoints, cutouts, clock,
etc.
5.2

NUMERICAL KEYPAD

The Numerical keypad provides all keys necessary to
program numerical values into the Micro Panel.
The "*" key is used to designate holidays when pro-
gramming special start/stop times for designated holi-
days in the SET SCHEDULE/HOLIDAY program
mode.
The "+/-" key allows programming -C setpoints and
cut-outs in the metric display mode.
5.3

ENTER KEY

The Enter key must be pushed after any change is made
to setpoints, cutouts, or system clock. Pressing this key
tells the micro to accept new values into memory. If
this is not done, the new values entered will be lost and
the original values will be returned.

5. ENTRY KEYS

The Enter key is also used to scroll through available
data when using the Program or Set Schedule/Holiday

keys.

5.4

CANCEL KEY

When the Cancel key is pressed, the cursor will always
return to the first character to be programmed in the
display message. This allows the operator to begin re-
programming, if an error is made. When the Cancel
key is pressed, the values already keyed in will be erased
and the original or internally programmed default val-
ues will appear. In other instances the display will re-
main the same and the only reaction will be the cursor
returning to the first character.

der the OPER DATA and HISTORY Key and to select
the correct day of the week and the correct month when
programming the micro with the correct time and date.
The # key also operates as a toggle AM/PM key if the
cursor is over "AM" or "PM" on the display. For ex-
ample, pressing the # key when the cursor is on "PM"
changes it to "AM."
