9-2-8. Setting of Remote Control
Selector Switch
When two indoor units are installed in the
separated rooms, there is no need to change
the select 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
and 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.
