wiring.
Use the remote control connection wire coming from the
indoor unit, and fi eld-supply wire and a wire joint to complete
the connection as shown in Fig. 8-6b. The remote control
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.

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.
