• When two indoor units are installed in the

a unit, two units may receive the remote
controller signal simultaneously and operate. In
this case, the operation can be preserved by

when the settings of indoor unit and remote
controller are different.
• There is no relation between A setting/B
setting and A room/B room when connecting
the piping and cables.
