Before starting operation
• Start running after the "HO" display has disappeared. The "HO" display
briefly appears on the room temperature display (max. 3 minutes) when
the power is turned on and after a power failure. This does not indicate
any failure of the air conditioner.
• The operation modes of the indoor units' cooling operation, dry opera-
tion, and heating operation are different from those of the outdoor units.
When the operation is started with cooling/dry (heating) and other in-
A
door units connected to the counterpart outdoor units are already run-
ning in the same operation mode, the remote control displays "
" " ("
") mode. However, the operation comes to stop, and you cannot
B
get a desired mode. When this occurs, you will be notified by the "
" " ("
") display that flashes in the liquid crystal display of the remote
controller. Set to the operation mode of other indoor unit by the opera-
tion switch button.
The above does not apply to the models that simultaneously run both
the cooling operation and heating operation.
• The outdoor units stop when all the indoor units connected to the coun-
terpart outdoor units stop.
• During heating operation, even if the indoor unit is set to operation while
the outdoor unit is in defrosting operation, operation starts after the de-
frosting operation of the outdoor unit has ended.
