5. After wiring is complete, make sure again that there is no slack on the connec-
tions, and attach the cover onto the terminal box in the reverse order of
removal.
Notes:
• Do not pinch the cables or wires when attaching the terminal box cover.
Doing so may cause a risk of disconnection.
• When accommodating the terminal box, make sure that the connectors on
the box side are not removed. If removed, it cannot operate normally.
9.4. External I/O specifications
1. Wiring should be covered by insulation tube with supplementary insulation.
2. Use relays or switches with IEC or equivalent standard.
3. The electric strength between accessible parts and control circuit should
have 2750 V or more.
9.5. Selecting the airflow mode and external static pressure
This indoor unit supports two types of airflow modes and four external static pressure settings. The fan speed and the corresponding airflow rate for each mode vary with
models as shown in the table below.
Notes:
• When the airflow mode and the static pressure setting were set from the remote controller, the actual setting and the switch setting on the control board may
not match because the latest setting from the remote controller overrides the previous setting. To check the latest airflow mode and static pressure setting,
check them on the remote controller, not on the switch.
• If the static pressure setting for the duct is lower than that for the unit, the fan of the unit may repeat start/stop, and the outdoor unit may remain in a stopped
state. Match the static pressure settings for the unit to that for the duct.
To set the airflow mode and the static pressure setting with the switches on the control board
To set the airflow mode and the static pressure setting from the function selection screen on the remote controller (Some remote controllers do not support
the function selection function. Refer to the Instruction Book of a given remote controller.)
Follow the instructions below and the instructions detailed in the remote controller manual for how to set the switches.
1. Set the function setting No. 32 (Switch setting/Function selection) to “2”.
2. Set the function setting No. 115 to appropriate values, according to the airflow mode and the static pressure setting.
9.6. Setting addresses
(Be sure to operate with the main power turned OFF.)
[Fig. 9.5.1] (P.6)
• There are two types of rotary switch setting available: setting addresses 1 to 9
and over 10, and setting branch numbers.
• 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.

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.
