(2) Cautions
1)
M-NET 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.
3)
Do not connect the terminal blocks (TB5) on the indoor units that are
connected to different outdoor units with each other.
4)
Replacement of male power jumper connector (CN41) must be per-
formed only on one of the outdoor units.
5)
Short-circuit the S (shield) terminal of the terminal block for the cen-
tral control unit (TB7) and the ground terminal (
unit whose power jumper was moved from CN41 to CN40.
6)
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.)
When the P200 and P250 models are not
included in the connected indoor units
When the P200 and P250 models are in-
cluded in the connected 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.
7) When a power supply unit is connected to the transmission
line for centralized control, leave the power jumper connec-
tor on CN41 as it is (factory setting).
