*1. When BS is connected to the system,
automatic address setup is not available.
(2) Cautions
1) ME remote controller and MA remote controller cannot both
be connected to the same group of indoor units.
2) No more than 2 MA remote controllers can be connected to
a group of indoor units. It is not possible to connect a pair of
PAR-30MAAU.
3) When the number of the connected indoor units is as shown
in the table below, one or more transmission boosters (sold
separately) are required.
To connect two transmission boosters, connect them in par-
allel. (Observe the maximum number of connectable indoor
units that are listed in the specifications for each outdoor
unit.)

are not included in the connect-
ed indoor units

The table above shows the number of transmission boost-
ers that is required by the system with three BC controllers.
For each BC controller that is subtracted from the above-
mentioned system, two additional indoor units can be con-
nected.
