Countermeasure

1. Remote controller display does not 

work.

. “PLEASE WAIT” display is remained 

on the remote controller.

. When pressing the remote controller 

operation switch the OPERATION 
display is appeared but it will be 
turned off soon.

 After cancelling to select function from the remote 

controller, the remote controller operation switch will 
not be accepted for approx. 0 seconds.

1

 Normal operation

1

 At longest  minutes after the power supply “PLEASE 

WAIT” is displayed to start up.

2

 Communication error between the remote controller 

and indoor unit

3

Check LED on indoor controller board.

   (1) When LED is lit.
        Check the remote controller wiring for  
        breaking or contact failure.
   () When LED is blinking.
        Check short circuit of remote controller 
        wiring.
