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”, SWU2 (for over 10) remains at “0”, and match SWU1 (for 1 to 9) to “3”.
b) How to set branch numbers SWU3 (only for R2 series)
Branch number matches the BC controller branch number. If two branches are used, SWU3 should be set to a
smaller branch number. For other than R2 series, remain SWU3 as "0".

(6)-2 Switch operation (WCB)
a) How to set addresses
Example: If Address is “3”, SWU2 (for over 10) remains at “0”, and match SWU1 (for 1 to 9) to “3”.

There are two branches for WCB. Indoor unit/PWFY connecting branch should be set as "0" and PWFY connecting
branch as "1".
