6.4. Connecting remote controller, indoor and
outdoor 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
controller.
• Connect the remote controller's transmission cable within 10 m using a 0.75 mm
core cable. If the distance is more than 10 m, use a 1.25 mm
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.
(Nonpolarized 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 change Pair No. setting, refer to installation manual attached to wireless re-
mote controller. (In the default setting of indoor unit and wireless remote control-
ler, Pair No. is 0.)

6.5. Setting addresses (Fig. 6-4)
(Be sure to operate with the main power turned OFF.)
• There are two 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.
6.6. Sensing room temperature with the built-in
sensor in a remote controller
If you want to sense room temperature with the built-in sensor in a remote
controller, set SW1-1 on the control board to "ON". The setting of SW1-7 and SW1-
8 as necessary also makes it possible to adjust the air flow at a time when the
heating thermometer is OFF.
