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 

fi

 rst unit that was turned on.

In this case, set the units that are turned on later to the same
operation mode as the 

fi

 rst unit.

Otherwise, they will enter the standby state, and the OPERATION
lamp will 

fl

 ash: 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 

fi

 rst unit to be turned on.

 CAUTION

Normally, the operation mode in the room where the unit is 

fi

 rst run is given priority, but the following situations are exceptions, so please keep 

• 

this in mind.
If the operation mode of the 

fi

 rst 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 

fl

 ash.

With the priority room setting active.

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 6°C or more below the highest temperature recorded that day. 

• 

Therefore, when the temperature difference is less than 4°C, this function will not be activated.
NIGHT QUIET mode reduces slightly the cooling ef

fi

 ciency of the unit.
