14.4. Error Codes Table
Note:
“O” - Frequency measured and fan speed fixed.
The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until “beep” sound heard
following by pressing the “CHECK” button at Remote Control.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error
Codes Table) by using Remote Control or Auto Switch at indoor unit. However, the Remote Control signal receiving sound is
changed from one “beep” to four “beep” sounds.
