Refer to 1.2.3. cause Code of I.U. or O.U. Stoppage
1. The cause code of indoor unit stoppage is not always “02” (Alarm) during stoppage by the abnormality.
If the unit is under Thermo-OFF by other cause of stoppage before “02” (Alarm) occurs, the previous cause code of indoor
unit stoppage remains.
2. When the communication between the indoor unit and the outdoor unit is disconnected for 3 minutes, the indoor micro-
computer will be reset. Accordingly when the alarm code “03” (Communication Failure between Indoor Unit and Outdoor
Unit) occurs, the cause code of indoor unit stoppage may be indicated “05”.
