Setting of Remote Control
Selector Switch
When two indoor units are installed in the separated rooms, it
is not necessary to change the selector switches.
Remote control selector switch
• When two indoor units are installed in the same room or
adjacent two rooms, if operating a unit, two units may receive
the remote control signal simultaneously and operate. In this
case, the operation can be preserved by setting either one
indoor unit or 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.
