2. An example of a system with one outdoor unit to which 2 or more LOSSNAY units are connected
(manual 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) 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.)
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.
(3) Maximum allowable length
1) Indoor/outdoor transmission line
Same as [5] 1.
2) Transmission line for centralized control
No connection is required.
3) MA remote controller wiring
Same as [5] 1.

* If the BC address overlaps any of the addresses that are assigned to either the OC, OS, or BS, use a different, unused address.
OC, OS, and BS addresses (lowest indoor unit address in the group plus +50) have higher priority than the BS address.
