[5] An Example of a System to which an MA Remote Controller is connected
1. System with one outdoor unit (automatic address setup for both indoor and outdoor units)
(1) Sample control wiring
(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 72 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 29)
5) To connect more than 2 LOSSNAY units to indoor units
in the same system, refer to the next section "[5] 2. An

more LOSSNAY units are connected".(page 29)
