It is easier if the optional remote controller is used
when setting the slave unit.
• Perform the following procedures when setting the mas-
ter and slave unit separately.
Procedure
(1)
Change the SECOND CODE NO. to “02”, individual
setting, so that the slave unit can be individually set.
( Refer to Table 10 )
(SECOND CODE NO. is factory set to “01”, unified
setting.)
Table 10
(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”, indi-
vidual setting.
(6)
Perform field setting for the slave unit.
(7)
Turn off the main power supply switch after (6).
(8)
If there is more than one slave unit, repeat steps 4 to
7.
(9)
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.)
10-7 CONTROL BY 2 REMOTE CONTROLLERS
(Controlling 1 indoor unit by 2 remote
controllers)
• When using 2 remote controllers, one must be set to
“MAIN” and the other to “SUB”.
MAIN/SUB CHANGEOVER

Insert a wedge-head screwdriver into the recess
between the upper and lower parts of remote control-
ler and, working from the 2 positions, remove care-
