*1. The figures above show a system to which two
outdoor units are connected, but only a single
outdoor unit can be connected in an HVRF
system.
(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 separately) 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.)

included in the connected indoor units

cluded in the connected indoor units
