6.4. Setting addresses (Fig. 6-6)
(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.

6.5. Switch setting for different ceiling heights (Fig. 6-6)
With this unit, the air flow rate and fan speed can be adjusted by setting the SWA
(slide switch). Select a suitable setting from the table below according to the instal-
lation location.
* Make sure the SWA switch is set, otherwise problems such as not getting cool/
warm may occur.

6.6. Sensing room temperature with the built-in sensor
in a remote controller (Fig.6-6)
If you want to sense room temperature with the built-in sensor in a remote
controller, 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 flow at a time when
the heating thermometer is OFF.
