6-4. Wiring System Diagram for Group Control
This diagram shows when several units (maximum of
8) are controlled by a remote controller (master unit).
In this case, a remote controller can be connected at
any indoor unit.
Wiring procedure
Wire according to the left diagram:
●
Address setting is executed automatically when the
outdoor unit is turned on.
●
Each successive unit will respond at one-second
intervals following the order of the group address
when the remote controller is operated.
●
Group control using 2 remote controllers.
It does not matter which of the 2 remote controllers
you set as the main controller.
When using multiple remote controllers (up to 2 of
them can be used), one is the main remote controller
and the other is the sub-remote controller.
●
To set up a sub-remote controller, change its
remote control address connector (RCU. ADR)
located on its PCB from main to sub position (main:
when shipped from factory).
