unit.)
• The wired remote controller only can control a group
control. The wireless remote controller is unavailable
for this control.
• For wiring procedure and wires of the individual line
(Identical refrigerant line) system, refer to “8 Electrical
connection” in this Manual.
• Wiring between indoor units in a group is performed in
the following procedure.
• Connect the indoor units by connecting the remote
controller wires from the remote controller terminal
blocks (A, B) of the indoor unit connected with a
remote controller to the remote controller terminal
blocks (A, B) of the other indoor unit. (Non-polarity)
• For address setup, refer to the Installation Manual
attached to the outdoor unit.
