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 “RESET” button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error
Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is
changed from one “beep” to four “beep” sounds.
