Note:
"○" – Frequency measured and fan speed fixed
" * "– For cooling only model, it is the indication when indoor heat exchanger sensor or indoor air intake sensor has
abnormality.
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 Code Table) by using remote control or Auto OFF/ON button at indoor unit. However, the remote
control signal receiving sound is changed from one "beep" to four "beep" sounds.
