The Entry Keys allows the user to view, 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 HIS-
TORY keys, the UP and DOWN arrow keys allow the
user to scroll through the various data screens. Refer to
the section on “Display/Print” keys for specific infor-
mation 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.
“ENTRY” KEYS
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.
