■ Manual address setting using a remote control
This procedure should be used if the indoor unit wiring is completed and the outdoor unit wiring has not been
started.
For this procedure the group remote control should not be connected. One individual remote control should be used
to set the address on each individual indoor unit (one unit at a time), by wiring the remote control directly to the
indoor unit that is to be addressed.
When the address setting procedure is completed for the individual indoor units the group remote control should
1
be connected as shown.
CAUTION

Connector
Do not close the connectors between the (U1, U2) and (U3, U4) terminals before completing all refrigerant line
