1 1 If simultaneous twin, triple or four, connect the remote controller to anyone of the indoor units. Can control all functions of the
indoor unit even if different models (different types) are mixed.
2 2 Do not use crossover wiring among indoor units with simultaneous twin, triple or quadro units. (Prohibited item.)
3 3 On simultaneous twin, triple or four, it is possible to connect one each of the remote controller optical receiving section
to each indoor unit.
15-4. Group control operation (Operating control of multiple refrigerant systems (2 to 16)
as one group)
• Multiple Slim air conditioners operate at the same setting (operating mode, set temperature, etc.). However, each outdoor
unit is turned on and off individually by the intake sensor.
• Can be used when there are restrictions when combining Free Combo Multi units (such as floor mount type and ceiling cassette,
ceiling suspended, ceiling recessed, etc.) Up to 16 refrigerant systems can be controlled as a group by one remote controller.
• The outdoor unit addresses must be set. An address can be between 0 and 15 with no duplicates. Also, always set one unit
as zero (0).
w Simultaneous twin, triple and quad are one refrigerant systems. They are not multiple refrigerant systems. Individual twin is
a two refrigerant system and addresses must be set for two refrigerant systems.

Outdoor unit address setting
• The address of each outdoor unit must be set when there is to be group control.
• The setting of the address of the outdoor unit is done by using DIP switch SW1 (3 to 6) on the circuit board of each outdoor
unit. (Factory setting: all are set to off).
• The address setting by SW1 is as follows.

1 1 When there is two remote controller
control, refer to two remote controller
control operation.
2 2 When there are different indoor unit
models mixed within the same
group, always set the outdoor unit
that is connected to the indoor unit
with the most functions (fan speed,
vanes, louvers, etc.) as the host
(refrigerant address = 00).
3 3 Do not use crossover wiring among
indoor units with simultaneous twin,
triple or quadro units.
