9-2-8. Setting of Remote Controller Selector
Switch
When two indoor units are installed in the
separated rooms, there is no need to change
the select switches.
Remote Controller 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
controller signal simultaneously and operate. In
this case, the operation can be preserved by
setting either one indoor unit and remote
controller 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
controller are different.
• There is no relation between A setting/B
setting and A room/B room when connecting
the piping and cables.
