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.

• 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.

NIGHT QUIET operation requires initial programming during installation. Please consult your retailer or dealer for assistance.
NIGHT QUIET operation reduces the operation noise of the outdoor unit during the nighttime hours to prevent annoyance to neighbors.
• The NIGHT QUIET operation is activated when the temperature drops 6°C or more below the highest temperature recorded that day.
When the temperature difference between the current outdoor temperature and the maximum outdoor temperature becomes less than 4°C,
the NIGHT QUIET operation will be stopped.
• NIGHT QUIET operation reduces slightly the cooling efficiency of the unit.
