4.5. Setting addresses (Fig. 4-4)
(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.
Note:
Please set the switch SW5 according to the power supply voltage.
• Set SW5 to 240 V side when the power supply is 230 and 240 volts.
• When the power supply is 220 volts, set SW5 to 220 V side.
