and over 10, and setting branch numbers.

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”.

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

8 as necessary also makes it possible to adjust the air flow at a time when the
heating thermometer is OFF.
