If there is more than one slave unit, repeat setting for each
8
Detach user interface from the slave unit, and reattach to the
master unit.
INFORMATION
▪ You do not need to rewire the user interface from the
master unit if the optional remote controller for slave
unit is used. However, remove the wires attached to the
user interface terminal board of the master unit.
▪ After the slave unit setting, remove the user interface
