7-17. Wiring System Diagram for Group Control
This diagram shows when several units (maximum of
8) are controlled by a signal receiving unit (main
unit). In this case, a signal receiving unit can be
connected at any indoor unit.
Group control using 2 signal receiving units
It does not matter which of the 2 signal receiving units
you set as the main controller.
Wiring procedure
Wire according to the diagram at left:
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.
When using multiple signal receiving units (up to 2
can be used), one is the main signal receiving
unit and the other is the sub-signal receiving unit.
To set up a sub-signal receiving unit, change its
remote control address connector (RCU. ADR)
located on its PCB from main to sub position
(main: when shipped from factory).
