Unit Controls
The Entry Keys allows the user to view or change pro-
grammed values. The ENTRY keys consist of an UP
ARROW key, DOWN ARROW key, and an ENTER/ADV
key.
UP AND DOWN ARROW KEYS
Used in conjunction with the OPER DATA and HISTORY
keys, the UP and DOWN arrow keys allow the user to
scroll through the various data screens. Refer to the sec-
tion on "Display/Print" keys for specific information on
the displayed information and specific use of the UP and
DOWN arrow keys.
The UP and DOWN arrow keys are also used for pro-
gramming the control panel such as changing cooling
setpoints, setting the daily schedule, changing safety
setpoints, unit options, and setting the clock.

ENTER/ADV key
The ENTER key must be pushed after any change is
made to the cooling setpoints, daily schedule, safety
setpoints, unit options, and the clock. Pressing this key
"enters" the new values into memory. If the ENTER key
is not pressed after a value is changed, the changes will
not be "entered" and the original values will be used to
control the condensing unit.
Programming and a description on the use of the UP
and DOWN arrow and ENTER/ADV keys are covered in
detail under the SETPOINTS, and UNIT keys.
