Seven-Segment Alert and System Status
Codes
Alert codes are displayed using the seven-segment display
located on the outdoor control.
NOTE — System fault and lockout alarm code displays
takes precedence over system status (cooling, heating
stages or defrost/dehumidification).
The seven-segment will display an abnormal condition
(error code) when detected in the system. A list of the
codes are shown in table 12.
RESETTING ALERT CODES
Alert codes can be reset manually or automatically:
4. Manual Reset
Manual reset can be achieved by one of the following
methods:
Disconnecting R wire from the main control's R
terminal.
Turning the indoor unit off and back on again
After power up all existing codes are cleared.
5. Automatic Reset
After an alert is detected, the main control continues to
monitor the unit's system and compressor operations.
When/if conditions return to normal, the alert code is
turned off automatically.
