of the iTM plus adaptor to ON position.
<plus ADP ADDRESS switch and TERM switch>
NOTE
If the two LEDs, CPU ALIVE and ALARM, both light up during power-on after installa-
tion, there is a possibility of a problem with the address assignment:
•An invalid address is set. (“0”, “1”, and “9” are not allowed.)
•A duplicate address is used.
You must assign a unique address between 2 and 8 for each iTM plus adaptor. Power
off the unit once, check and correct the address, and then turn it on again.
Check the status of the two LEDs, CPU ALIVE and ALARM.

2.2 Connecting DIII-NET-compatible air conditioning equipment
DIII-NET is a unique air conditioning equipment communication capability developed by
DAIKIN. Using DIII-NET, you can centrally control multiple DIII-NET-compatible air condi-
tioning devices by connecting them to your intelligent Touch Manager.
The iTM plus adaptor allows you to connect additional 64 groups of air conditioners per
unit. Considering that the intelligent Touch Manager can be connected with a maximum of
seven iTM plus adaptors, you can control a total of 512 groups of air conditioners at a
maximum using a single intelligent Touch Manager.
WARNING
•Be sure to perform the operation during power-off conditions. Not doing so
may cause an electric shock.
•The maximum length of adhered wiring of high current electrical line of power
wires and weak current line of communication wires must be kept to 65 ft. or
less.
NOTE
The setting range of DIII address for the air conditioners controlled via the iTM plus
adaptor is also from “1-00” to “4-15”. The intelligent Touch Manager adds a DIII-NET
port number to each address for identication. For example, “2:1-00” and “3:1-02”.

2.2.3 Precautions for using multiple centralized controllers
The “centralized controller” refers to the equipment (e.g. the intelligent Touch Manager)
that control multiple air conditioners. Besides the intelligent Touch Manager, the DAIKIN's
product portfolio includes a wide range of centralized controllers suitable for different
applications or building sizes, which can be used in combination to construct an optimal
air conditioning control system.
If multiple centralized controllers are connected on the DIII-NET network, you must set
MASTER and SLAVE relationship for those controllers.
Assign only one of those controllers to MASTER, and other controllers to SLAVE.
The iTM plus adaptor is set to MASTER by default. Change the setting to SLAVE in any of
the following cases:
•Where Interface for use in BACnet is installed in parallel.
•Where Interface for use in LONWORKS is installed in parallel.
•If there is another intelligent Touch Manager or iTM plus adaptor which is assigned to
MASTER.
