ues programmed in as chiller setpoints, cutouts, clock,

5.2 NUMERICAL KEYPAD
The Numerical keypad provides all keys necessary to

cutouts in the metric display mode.

The Enter key must be pushed after any change is

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.

data when using the Program, Operating Data, His-
tory, or Set Schedule / Holiday keys.

return to the first character to be programmed in the

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.
