Turn off the main power supply switch after (2).
4
Detach remote controller from the master unit and connect it to
the slave unit.

Turn on the main power supply switch again, and as in (1),
change the Second code No. to "02", individual setting.

and reattach to the master unit. This is the end of the setting
procedure.
You do not need to rewire the remote controller from the master unit if
the optional remote controller for slave unit is used. (However,
remove the wires attached to the remote controller terminal board of
the master unit.)
