For group control, install connection cables between the unit and package air conditioner indoor units.
• Connect the cables to terminals X, Y and Z in the interface unit. Each terminal has polarity, so be sure to connect wires to the
corresponding terminals at each end.
• Use cables with a size of 0.5 mm
2
or larger. (cables that are large enough to endure the
routing required)
• Keep the total length of connection cables and remote control wiring to within 600 m.

Set the address in each unit.
Set the address of using the rotary switch on the circuit board inside each unit. (“0” ~ “F”)
Set the addresses in each group so that there is no overlapping of addresses.
After turning on the power, the indoor unit’s address is displayed when the Air
Conditioner No. button on the remote control is pressed, so check if the indoor unit
addresses is displayed in the remote control’s display when the and buttons
are pressed to select each unit.

Cautions when extending the connection cable length
Cut jumper wire “J2” on the circuit board.
Caution: Both the wired remote control and the wireless remote control supplied with the
indoor unit cannot be used together.
Strip off the sheath material from the connection
cable wires inside the wired remote control case.
The length of wire with the sheathing removed
should be as shown below for each wire.
Black: 195 mm
White: 205 mm
Red:

Connect the interface and remote control.
The terminals have polarity, so be sure to connect the wires to the corresponding terminal on each end.
Be sure to strip off the only the proper length of sheath material from each connection cable in the interface unit.
