*1. When BS is connected to the system,
automatic address setup is not available.
(2) Cautions
1) M-NET remote controller and MA remote controller can-
not 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.)
When the P200 and P250 mod-
els are not included in the con-
nected indoor units
When the P200 and P250 mod-
els are included in the connect-
ed indoor units
The table above shows the number of transmission
boosters 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 connected.

4) Automatic address setup is not available if start-stop in-
put(CN32, CN51, CN41) is used for a group operation of
indoor units. Refer to "[5] 2. Manual address setup for
both indoor and outdoor units"
5) To connect more than 2 LOSSNAY units to indoor units
in the same system, refer to the next section "[5] 2. An
example of a system with one outdoor unit to which 2 or
more LOSSNAY units are connected".
