6.4. Connecting remote controller, indoor and out-
door transmission cables (Fig. 6-3)
Connect indoor unit TB5 and outdoor unit TB3. (Non-polarized 2-wire)
The “S” on indoor unit TB5 is a shielding wire connection. For specifications
about the connecting cables, refer to the outdoor unit installation manual.
Install a remote controller following the manual supplied with the remote control-
ler.
Connect the remote controller’s transmission cable within 10 m using a 0.75 mm²
core cable. If the distance is more than 10 m, use a 1.25 mm² junction cable.

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 con-
troller board.
When more than two units are run under group control using wireless remote
controller, connect TB15 each with the same number.
To chang Pair No. setting, refer to installation manual attached to wireless remote
controller. (In initial setting of indoor unit and wireless remote controller, Pair No.
is 0.)

6.5. Setting addresses (Fig. 6-4)
(Be sure to operate with the main power turned OFF.)
• 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.
