*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.

4) Automatic address setup is not available if start-stop input
(CN32, CN51, CN41) is used for a group operation of indoor
units or when multiple indoor units with different functions
are grouped in the same group. Refer to the following
page(s). [2-7-2 Single Refrigerant System with Two or More
LOSSNAY Units](page 34)
5) For information about connecting two or more LOSSNAY
units to a system, refer to the following page(s). [2-7-2 Sin-
gle Refrigerant System with Two or More LOSSNAY
Units](page 34)
(3) Maximum allowable length

2) Transmission line for centralized control
No connection is required.
3) MA remote controller wiring

*When connected to the terminal block on the Simple re-
mote controller, use cables that meet the following cable
size specifications: 0.75 - 1.25 mm
*When connecting PAR-30MAAU, use a 0.3 mm
sheathed cable.
