Example System with an MA and an ME Remote Controller

2-9-1 System with a Connection of System Controller to Centralized Control
Transmission Line
(1) Sample control wiring
(2) Cautions
1) Be sure to connect a system controller.
2) ME 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 addresses that are smaller than those of the in-
door units that are connected to the ME remote control-
ler.
4) No more than 2 ME 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) Replacement of male power jumper connector (CN41)
must be performed only on one of the outdoor units (not
required if power to the transmission line for centralized
control is supplied from a controller with a power supply
function, such as AE-200E).
8) Provide an electrical path to ground for the S terminal on
the terminal block for centralized control (TB7) on only
one of the outdoor units.
9) A transmission booster must be connected to a system

Note1 When only the LM adapter is connected,
leave SW5-1 to OFF (as it is).
Note2 LM adapters require the power supply
capacity of single-phase AC 220/240V.
in which the total number of connected indoor units ex-
ceeds 20.
10) A transmission booster is required in a system to which
more than 16 indoor including one or more indoor units
of the 200 model or above are connected.
Refer to the DATABOOK for further information about
how many booster units are required for a given system.
11) 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 2-7-3
2) Transmission line for centralized control
Same as 2-7-4
3) MA remote controller wiring
Same as 2-7-1
4) M-NET remote controller wiring
Same as 2-8-1
5) Maximum line distance via outdoor unit
2
(1.25 mm [AWG16] min. )
