installation manual of the remote controller.
Setting ceiling height
Adjust the Second code No. according to the table below so that it
corresponds to the ceiling height of your installation. (Second code
No. is factory set to "01")
The figure of ceiling height is for air discharge in all directions.
Setting air discharge direction
For changing air discharge direction (2, 3 or 4 directions), refer to the
option handbook of the optional blocking pad kit. (Second code No. is
factory set to "01" for all-round air discharge)

Setting indoor unit number of simultaneous operation
system
When using in simultaneous operation system mode, change the
Second code No. as shown in the table. (Second code No. is factory
set to "01" for 1 connected unit.)
When using in simultaneous operation system mode, refer to
"Simultaneous operation system individual setting" on page 8
to set
master and slave units separately.
When using wireless remote controllers
When using wireless remote controllers, wireless remote controller
address setting is necessary. Refer to the installation manual
attached to the wireless remote controller for setting instructions.
Simultaneous operation system individual setting
It is easier if the optional remote controller is used when setting the
slave unit.
Perform the following procedures when setting the master and slave
unit separately.
Procedure
(See figure 17)
1
Change the Second code No. to "02", individual setting, so that
the slave unit can be individually set. (Second code No. is
factory set to "01", unified setting.)
2
Perform field setting for the master unit.
3
Turn off the main power supply switch after (2).
4
Detach remote controller from the master unit and connect it to
the slave unit.
5
Turn on the main power supply switch again, and as in (1),
change the Second code No. to "02", individual setting.
6
Perform field setting for the slave unit.
7
Turn off the main power supply switch after (6).
In case there are 2 or more slave units, repeat steps (4) to (7) for
all slave units.
8
Detach the remote controller from the slave unit after the setting,
and reattach to the master unit. This is the end of the setting
procedure.
You do not need to rewire the remote controller from the master unit if
the optional remote controller for slave unit is used. (However,
remove the wires attached to the remote controller terminal board of
the master unit.)
