Note for Multi System
Multi system has one outdoor unit connected to multiple indoor units.
■
Selecting the operation mode
With the priority room setting present but
inactive or not present.
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 as the first unit.
Otherwise, they will enter the standby state, and the OPERATION
lamp will flash: this does not indicate malfunction.
NOTE
■
Notes on operation mode for multi system
• COOL, DRY and FAN operation may be used at the same time.
• AUTO operation automatically selects COOL operation or HEAT operation based on the room temperature.
Therefore, AUTO operation is available when selecting the same operation mode as that of the room with the first unit to be turned on.
CAUTION
• 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 operation, then using HEAT operation in any room after this will give priority to HEAT operation. In
this situation, the air conditioner running in FAN operation will go on standby, and the OPERATION lamp will flash.
With the priority room setting active.
Refer to priority room setting on the next page.
■
NIGHT QUIET mode (Available only for COOL operation)
NIGHT QUIET mode requires initial programming during installation. Please consult your retailer or dealer for assistance.
NIGHT QUIET mode reduces the operation noise of the outdoor unit during the nighttime hours to prevent annoyance to
neighbors.
• The NIGHT QUIET mode is activated when the temperature drops 5°C or more below the highest temperature recorded that day. Therefore,
when the temperature difference is less than 5°C, this function will not be activated.
• NIGHT QUIET mode reduces slightly the cooling efficiency of the unit.

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.
