(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 does not matter if the refrigerant address settings are same with the different group.

※It is not good with the above setting in the group B because the outdoor unit which has the refrigerant
address 00 does not have the minimum M-NET address 3 in the group. Make the outdoor unit of the
refrigerant address set with the minimum address in the group like the group A.
