4.4. Connecting remote controller, indoor and outdoor
• 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 con-
necting 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 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 remote
controller. (In the default setting of indoor unit and wireless remote controller, Pair
No. is 0.)
4.5. Setting addresses (Fig. 4-6)
(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
2 How to set branch numbers SW14 (Series R2 only)
• 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.
4.6. Sensing room temperature with the built-in sensor
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.

(for 1 to 9) with "3".
Match the indoor unit's refrigerant pipe with the BC controller's end connection
number.
Remain other than series R2 at "0".
