(2) Cautions
1) Be sure to connect a system controller.
2) M-NET remote controller and MA remote controller cannot both be
connected to the same group of indoor units.
3) Assign to the indoor units connected to the MA remote controller ad-
dresses that are smaller than those of the indoor units that are con-
nected to the M-NET remote controller.
4) No more than 2 M-NET remote controllers can be connected to a
group of indoor units.
5) No more than 2 MA remote controllers can be connected to a group
of indoor units.
6) Do not connect the terminal blocks (TB5) on the indoor units that are
connected to different outdoor units with each other.
7) Replace the power jumper connector of the control board from CN41
to CN40 on only one of the outdoor units.
8) Provide an electrical path to ground for the S terminal on the terminal
block for centralized control on only one of the outdoor units.
9) 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 left table shows the number of transmission boost-
ers that is required by the system with three BC control-
lers. For each BC controller that is subtracted from the
above-mentioned system, two additional indoor units
can be connected.
10) When a power supply unit is connected to the transmis-
sion line for centralized control, leave the power jumper
connector on CN41 as it is (factory setting).
(3) Maximum allowable length
1) Indoor/outdoor transmission line
Same as [5] 3.
2) Transmission line for centralized control
Same as [5J 4.
3) MA remote controller wiring
Same as [5] 1.
4) M-NET remote controller wiring
Same as [6]
