Table 8. Outdoor Control Seven-Segment Unit Status Displays (continued)
Description
Idle Mode: Decimal point blinks at 1 Hz
Soft Disabled: Top and bottom horizontal line and decimal point
blink at 1 Hz.
O.E.M test mode
Anti-Short Cycle Delay
Cooling Stage: Shows what stage of cooling is currently operat­
ing.
Heat Pump Stage: Shows what stage of heat pump is currently
operating.
Defrost Mode: Shown only while in an active defrost.
Dehumidification mode: Shows that the unit is providing dehu­
midification instead of straight cooling.
Diagnostic recall: Shows the last 10 stored diagnostic error
codes.
Fault Memory clear
Active error in outdoor control Idle mode: Shown all active
error(s) codes.
Active error in run mode: Shown current status and all active
error(s) codes.
Outdoor Ambient Temperature (OAT): Any time OAT is sensed
in operating range value is displayed if unit is in diagnostic and
non-diagnostic modes.
Outdoor Coil Temperature (OCT): Any time OCT is sensed in
operating range value is displayed if unit is in diagnostic mode.
Discharge Line Temperature (DIS): Any time DIS is sensed in
operating range value is displayed if unit is in diagnostic mode.

Example of Display
Idle Mode: Decimal point blinks at 1 Hz (0.5 second on, 0.5 second off).
Display OFF.
Soft Disabled: Top and bottom horizontal line and decimal point blink at 1
Hz (0.5 second on, 0.5 second off). Note: Control should be replace.
All segments flashing at 2 Hz (unless error is detected) Note: Control
should be replace.
Middle line shall blink at 1 Hz for 2 seconds, followed by a 2 second display
of the rounded up number of minutes left in the timer (2 minutes 1 second
shall be displayed as "3"). The Anti-Short Cycle Delay time remaining is
displayed whenever the delay is active.
Following string is repeated if second stage cooling is active with outdoor
fan speed set at 700 RPM. Note: A - If available, displays outdoor ambient
temperature.
