Malfunction-diagnosis method at maintenance service>
9-2. MALFUNCTION-DIAGNOSIS METHOD BY REMOTE CONTROLLER
<In case of trouble during operation>
When a malfunction occurs to air conditioner, both indoor unit and outdoor unit will stop and operation lamp blinks to inform
unusual stop.
• "CHECK" lights, and refrigerant
address "00" blinks.
• Check that the remote controller's
display has stopped before continuing.
• Select the refrigerant address of the
indoor unit for the self-diagnosis.
Note: Set refrigerant address using the
outdoor unit’s DIP switch (SW1).
(For more information, see the
outdoor unit installation manual.)
• If an air conditioner error occurs, the
indoor unit's sensor emits an intermit-
tent buzzer sound, the operation lamp
blinks, and the error code is output.
(It takes 3 seconds at most for error
code to appear.)
• The check mode is cancelled.
