room A
When more than one indoor unit is operating, priority is
given to the first unit that was turned on.
In this case, set the units that are turned on later to the
same operation mode (*1) as the first unit.
Otherwise, they will enter the Standby Mode, and the
operation lamp will flash; this does not indicate malfunction.
• COOL, DRY and FAN mode may be used at the same time.
• AUTO mode automatically selects COOL mode or HEAT mode based on the room temperature.
Therefore, AUTO mode is available when selecting the same operation mode as that of the room
with the first unit to be turned on.
Normally, the operation mode in the room where the unit is first run is given priority, but the following situations are
exceptions, so please keep this in mind.
If the operation mode of the first room is
FAN Mode
, then using
Heating Mode
in any room after this will give priority to
heating.
In this situation, the air conditioner running in FAN Mode will go on standby, and the operation lamp will flash.
When using the OUTDOOR UNIT QUIET operation feature with the Multi system, set all indoor units to
OUTDOOR UNIT QUIET operation using their remote controllers.
When clearing OUTDOOR UNIT QUIET operation, clear one of the operating indoor units using their remote controller.
However OUTDOOR UNIT QUIET operation display remains on the remote controller for other rooms.
We recommend you release all rooms using their remote controllers.
