operate. In this case, the operation can be preserved
by setting either one remote control to B setting.
(Both are set to A setting in factory shipment.)

•

   

The remote control signal is not received when the 

settings of indoor unit and remote control are different.

•

  

There is no relation between A setting/B setting and A

room/B room when connecting the piping and cables.

<Remote control A-B selection>

To separate using of remote control for each indoor unit

in case of 2 air conditioners are installed nearly.

Remote Control B Setup.
