The "S" on indoor unit TB5 is a shielding wire connection. For specifi cations about
the connecting cables, refer to the outdoor unit installation manual.
• Install a remote controller following the manual supplied with the remote controller.
• Connect the remote controller's transmission cable within 10 m, 33 ft using a
2
0.75 mm (AWG18) core cable. If the distance is more than 10 m, 33 ft, use a 1.25
mm 2 junction cable.
1
MA Remote controller
• Connect the "1" and "2" on indoor unit TB15 to a MA remote controller. (Non-polarized
2-wire)
• DC 9 to 13 V between 1 and 2 (MA remote controller)
2
M-NET Remote controller
• Connect the "M1" and "M2" on indoor unit TB5 to a M-NET remote controller. (Non-
polarized 2-wire)
• DC 24 to 30 V between M1 and M2 (M-NET remote controller)
3
Wireless remote controller(When installing wireless signal receiver)
• Connect the wire of wireless signal receiver (9-pole cable) to CN90 of indoor control-
ler board.
• When more than two units are run under group control using wireless remote
controller, connect TB15 each with the same number.

• There are 2 types of rotary switch setting available: setting addresses 1 to 9 and
over 10, and setting branch numbers.
1
How to set addresses
Example: If Address is "3", remain SW12 (for over 10) at "0", and match
SW11(for 1 to 9) with "3".
2
How to set branch numbers SW14 (Series R2 only)
Match the indoor unit's refrigerant pipe with the BC controller's end connection
number.
Remain other than series R2 at "0".
• The rotary switches are all set to "0" when shipped from the factory. These switches
can be used to set unit addresses and branch numbers at will.
• The determination of indoor unit addresses varies with the system at site. Set them
referring to the Data Book.
