5. After wiring is complete, make sure again that there is no slack on the con-
nections, and attach the cover onto the terminal bed box in the reverse order
of removal.
Notes:
• Do not pinch the cables or wires when attaching the terminal bed box
cover. Doing so may cause a risk of disconnection.
• When accommodating the terminal bed box, make sure that the con-
nectors on the box side are not removed. If removed, it cannot operate
normally.

10.4. Selecting the power source

It is 230V setting at factory shipment.
So, it is necessary to change the setting in other power supply districts.
Please remove the connector of motor from the control box, and insert the attach-
ment connector according to each power supply between those.
The connector colors are as follows.
Power source 230V

10.5. Setting addresses

(Be sure to operate with the main power turned OFF.)
[Fig. 10.5.1] (P.5)
<Address board>
• There are two types of rotary switch setting available: setting addresses 1 to
9 and over 10, and setting branch numbers.
A 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".
B How to set branch numbers SW14 (Series R2 only)
Match the indoor unit's refrigerant pipe with the BC controller's end con-
nection number. Remain other than 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 technical data.
Notes:
Please set the switch SW5 according to the power supply voltage.
• Set SW5 to 240V side when the power supply is 230 volts.
• When the power supply is 208 volts, set SW5 to 220V side.
10.6. 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 con-
troller, set SW1-1 on the control board to "ON".
