9.5. Selecting the external static pressure
As the factory setting is for use under an external static pressure of 0.20 in. WG (50
Pa), no switch operation is needed when using under the standard condition.

9.6. Setting addresses
(Be sure to operate with the main power turned OFF.)
[Fig. 9.5.1] (P.5)
<Indoor controller board>
•
There are two 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)
The branch number assigned to each indoor unit is the port number of the
BC controller to which the indoor unit is connected.
Leave it to "0" on the non-R2 series of units.
•
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.

9.7. Sensing room temperature with the
Switch operation
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
