EXAMPLES
„ „
Example 1 : To automatically set both addresses of signal amplifiers and
„ z
indoor units
Step 1:

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.)
Step 2:

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.
Step 3:

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.
Step 4:

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.
1: If the total wiring length within a segment is expected to exceed 500 m, insert a signal amplifier (Refer to 5-3-2).

2: If the number of nodes (the number of units of indoor units, outdoor units, controllers and others) is expected to

exceed 64 (including signal amplifiers), insert a signal amplifier (Refer to 5-3-2).
Caution
Before activating the Automatic Address Setting function, make sure to finish setting the refrigerant ●
circuit addresses of outdoor units.
Setting the addresses of indoor units automatically does not necessary mean that addresses are
●
assigned sequentially starting from the indoor unit which is located the closest to the outdoor units
(instead, addresses are assigned randomly).
With respect to the setting of refrigerant circuit addresses, the same address numbers of the
refrigerant circuit addresses of the outdoor units being connected within the same refrigerant
system are assigned.
To find out what addresses have been assigned to individual indoor units, it is necessary to ●
perform a separate address check operation.
