  on page 364 about the operation distance.

It is necessary to change setting of interface PCB and wireless remote controller.
(1) Interface PCB 

Set SW1-1 to “OFF” position.

(2) Wireless remote controller

Pressing ACL  and  AIR FLOW button at the same time or inserting the batteries with 
pressing  AIR FLOW button will customize the signal.

VRF system (except heat recovery 3-pipe system) cannot be operated in Auto mode.
Make sure to set the remote controller for the models so as not to be able to choose 
Auto mode.
Pressing ACL  and  MODE button at the same time or inserting the batteries with 
pressing  MODE button will make auto mode operation.

ATTENTION

When the batteries are removed, the setting will return to the default setting. Please 
make sure to reset it when the batteries are replaced.

     Caution

The backup switch is provided on the receiver section. It is possible to use the backup switch as shown in the 
figure below. When operation from the wireless remote controller unit is not possible (due to flat batteries, a 
mislaid unit, a unit failure), the backup switch can be used as an emergency means. The backup switch is 
operated manually.
(1) If pressed while the air conditioner is in a halt, it will cause the air conditioner to start operation in the 

automatic mode (in the case of cooling only, in the cooling mode).
Fan speed: Hi fan, Temperature setting: 23

C, Louver: horizontal

(2) If pressed while the air conditioner is in operation, it will stop the air conditioner.

• After safety confirmation, turn on the power.
• Transmit a cooling operation command with the wireless remote controller, while the backup switch on the 

receiver is depressed.

• If the backup switch on the receiver is pressed during a test run, it will end the test run.
• If the air conditioner can not operate properly during the test run, check wiring according to the trouble shooting 

guides.

Up to 16 indoor units can be connected.

    Connect indoor units with each other with 2-core wires. As 

for size, refer to the following note.

The receiver wires must be connected only with the indoor 

unit that will be operated by the remote controller directly.

    Use the rotary SW1 and SW2 provided on the indoor unit 

PCB (Printed circuit board) to set unique remote control 
communication address avoiding duplication.
