(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) A transmission booster is required in a system to which
more than 32 indoor units (26 units if one or more indoor
units of the 200 model or above is connected) are con-
nected.
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".(page 30)
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".(page 30)
