 Activate the Signal Amplifier Automatic Address Setting function on the master
unit of Refrigerant System 1.
An address is automatically assigned to all signal amplifiers on the network.
(Because an address is also assigned to the signal amplifiers being
connected in Refrigerant Systems 2 and 3, it is not necessary to perform the
automatic address setting of these signal amplifiers again on the master units
of Refrigerant Systems 2 and 3.)
 Activate the Indoor Unit Automatic Address Setting function on the master unit
of Refrigerant System 1.
An indoor unit address and a refrigerant circuit address are automatically set
up for all indoor units being connected in Refrigerant System 1.
 Activate the Indoor Unit Automatic Address Setting function on the master unit
of Refrigerant System 2.
An indoor unit address and a refrigerant circuit address are automatically set
up for all indoor units being connected in Refrigerant System 2.
 Activate the Indoor Unit Automatic Address Setting function on the master unit
of Refrigerant System 3.
An indoor unit address and a refrigerant circuit address are automatically set
up for all indoor units being connected in Refrigerant System 3.
 Activate the RB Unit Automatic Address Setting function on the master unit of
Refrigerant System 1.
A RB unit address and a refrigerant circuit address are automatically set up
for all RB units being connected in Refrigerant System 1.
 Activate the RB Unit Automatic Address Setting function on the master unit of
Refrigerant System 2.
A RB unit address and a refrigerant circuit address are automatically set up
for all RB units being connected in Refrigerant System 2.
