3. Wiring method for M-NET
(1) Attention
① Outside of the unit, the wires for transmission (called for transmit wires later) should keep away (5 cm
or more) from power cable not to receive electric noise. (Never put the transmit wires and power cable
in the same cable pipe.)
② Never supply voltage 220V-240V to the terminals (TB7) for transmission. If the voltage is supplied, it
can break the electronic parts on the A-M CONVERTER board.
③ Use the shielded cable (CVVS, CPEVS) of 1.25mm square thickness with 2 wires for the transmission
cable. Never use transmit wires of different system with a cable which contains multi wires. The
communication of transmit signals will not work properly and it can cause wrong operation.

Between the outdoor units, it is OK that only M-NET wiring (2 wires, no polarity) is done.
(2) M-NET address setting
Make M-NET setting and refrigerant address setting on only outdoor unit.
There is no address settings for outdoor unit and remote controller like City Multi system.
The M-NET address setting for taking into centralized control system should be done only to the
outdoor unit.
The address set number should be 1-50 same as for City Multi indoor unit and make set in order of
number for the same group.

(3) Refrigerant address setting
In case that the A control Slim is set for group between different refrigerant (when multiple refrigerant
system is set in one group), it is necessary to make refrigerant address setting besides the wiring for
remote controller (TB5) between the indoor untis.
In case that the group setting is not done, be sure to leave the refrigerant address set for 00.
The refrigerant address is set by dip switch SW1 (3-6) on the outdoor controller of the outdoor unit.
(Factory settings are all OFF ・・・・・Refrigerant address 00).

(4) Limitation for address settings
In case of group operation, the M-NET address settings and the refrigerant address settings should be
done with the procedure above.
However, make the minimum M-NET address settings in the group for the outdoor unit which has the
refrigerant address 00.

※It is not good with the above setting in the group B because the outdoor unit which has the refrigerant

refrigerant address set with the minimum address in the group like the group A.

Attention for A control Slim M-NET connection
Pay attention to the next points for wiring of shielded wires.
CAUTION
The shielded wires of M-NET transmission should be connected with
the ground wire at any only one place of the unit to be connected.
It can cause the transmission error due to noise.
Outdoor unit digital LED display reads "Ed" error.
Centralized control remote controller reads "0403" error.
