(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.
3) When the number of the connected indoor units is as shown in
the table below, one or more transmission boosters (sold sepa-
rately) are required.
To connect two transmission boosters, connect them in parallel.
(Observe the maximum number of connectable indoor units that
are listed in the specifications for each outdoor unit.)
