SWU2 SWU1
• 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 SWU2 (for over 10) at "0", and match SWU1 (for 1 to 9) with "3".
b) How to set branch numbers SWU3 (Series R2 only)
Match the indoor unit's refrigerant pipe with the BC controller's end connection 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.
