10-16-2. Basic wiring diagram 2
Group control (when a central control device is not used)
● A maximum of 8 indoor units can be connected to a single
remote controller.
Example: In a refrigerant system where 2 or 3 indoor units
are connected to 1 outdoor unit, set the new
system address (refrigerant system address)
before turning ON the remote power switch.
(Refer to 10-16-3.)
(Set using the system address black rotary switch
on the outdoor unit control PCB.)
(for single-phase outdoor unit)
1. Wall-mounted units do not include a terminal plate for
connecting a remote controller.
2. For group control of wall-mounted units, connect
the remote controller crossover wiring to the remote
controller connector (2P) on the main unit, as shown in
the diagram.
(Wiring procedure)
(1) Set the No. 1 wall-mounted indoor unit so that it can be
operated by the wireless remote controller.
(This is set at the time of shipment.)
On the indoor unit control PCBs, set the No. 2 and
following wall-mounted units to the sub remote controller.
(Refer to Item 10-16-5.)
(2) Connect the crossover wiring to 1 and 2 on the remote
controller wiring terminal plates of the No. 1 indoor unit
and the other indoor units (as shown in Basic wiring
diagram 2).
(3) Connect the inter-unit control wiring to 1 and 2 on the No.
1 indoor unit terminal plate, and to 1 and 2 on the outdoor
unit terminal plate.
Connect the wiring in the same way from the other outdoor
units to U1 and U2 on the indoor units terminal plates
(different refrigerant system).
(4) Perform automatic address setting from the outdoor unit.
(For the automatic address setting procedure, refer to
10-16-4.)

* Models with auxiliary heaters cannot be used for "crossover
wiring" of the indoor unit power wires. (Use a pull box to divide
the wiring.)
* Be sure to use the indoor unit temperature sensor (body
sensor) when using this control. (Status at shipment)
