11-8-2. Basic wiring diagram 2

Group control (when a central control device is not used)

Simultaneous-operation multi system
A maximum of 8 indoor units can be connected to 1 remote controller.
Set the system address (refrigerant tubing system address) before turning on the remote power switch.
(Refer to 11-8-3. Setting the system addresses.)
(Set using the system address rotary switch on the outdoor unit control PCB.)

Fig. 11-6a

(Wiring procedure)

(1) Connect the remote controller to the indoor unit remote controller

wiring.

Use the remote controller connection wire coming from the

indoor unit, and field-supply wire and a wire joint to complete

the connection as shown in Fig. 11-6b. The remote controller

connection wire coming from the indoor unit includes a

connector, therefore cut off the connector and use the wire

joint to connect the wire from the remote controller.

(2) Connect the indoor units (U1, U2) and the outdoor units (1, 2).

Connect the other outdoor units and indoor units (with different

refrigerant systems) in the same way.

Connect the inter-unit control wiring to the indoor units (U1, U2)

for each refrigerant system.
