11.   SELECTING THE REMOTE  

   CONTROLLER SIGNAL CODE

When 2 or more air conditioners are installed in a room and the remote 
controller is operating an air conditioner other than the one you wish to 
set, change the signal code of the remote controller to operate only the air 
conditioner you wish to set (4 selections possible).

When two or more air conditioners are installed in a room, please contact 
your retailer to set the individual air conditioner signal codes.

Selecting the Remote Controller Signal Code

Use the following steps to select the signal code of the remote controller. 
(Note that the air conditioner cannot receive a signal code if the air 
conditioner has not been set for the signal code.)

1

  Press the START/STOP button until only the clock is displayed on the 

remote controller display.

2

  Press the MODE button for at least 5 seconds to display the current 

signal code (initially set to  ).

3

  Press the SET TEMP. (

) (

)  button to change the signal code 

between 

 

Match the code on the display to the air conditioner signal code.

4

  Press the MODE button again to return to the clock display. The signal 

code will be changed.

10°C HEAT

If no buttons are pressed within 30 seconds after the signal code is 
displayed, the system returns to the original clock display. In this case, 
start again from step 1.

The air conditioner signal code is set to A prior to shipment. Contact your 
retailer to change the signal code.

The remote controller resets to signal code A when the batteries in the 
remote controller are replaced. If you use a signal code other than signal 
code A, reset the signal code after replacing the batteries.

If you do not know the air conditioner signal code setting, try each of the 
signal codes (

) until you find the code which operates the air 

conditioner.

12.   TEST OPERATION

The outdoor unit may not operate depending on the room temperature. In 

this case, press the test run button on the remote controller while the air 

conditioner is running. (Point the transmitter section of the remote controller 

toward the air conditioner and press the test run button with the tip of a 

ballpoint pen, etc.)
