If you want to sense room temperature with the built-in sensor in a remote control-
ler, set SW1-1 on the control board to "ON". The setting of SW1-7 and SW1-8 as
necessary also makes it possible to adjust the air fl ow at a time when the heating
thermometer is OFF.

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.
How to set addresses
1
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)
2
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.
