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.
10-5 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
(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”, 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 sub-unit, repeat steps (4) – (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.)
(Refer to Fig. 30 on “9. WIRING EXAMPLE”)
10-6 When implementing group control
• When using as a pair unit or as a parent unit for simultaneous operation multi, you may simultaneous start/
stop (group) control up to 16 unit with the remote controller.
•
In this case, all the indoor units in the group will operate in accordance with the group control remote con-
troller
.
• Select a remote controller which matches as many of the functions (swing flap, etc) in the group as possible.
Wiring Method
(1) Remove the terminal box lid. (See ‘‘8. ELECTRIC WIRING WORK’’.)
(2) Cross-wire the terminal block for remote controller (P
