■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.

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.

(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.

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.
蘆It can cause the transmission error due to noise.
Outdoor unit digital LED display reads "Ed" error.
Centralized control remote controller reads "0403" error.
