3.2 Connecting DIII-NET compatible air conditioners
DIII-NET is an original DAIKIN air conditioner communication protocol.
Using DIII-NET, you can centrally control multiple DIII-NET-compatible air conditioning
devices by connecting them to your DGE601A51 or iTM.
1 DGE601A52 allows you to connect 64 additional air conditioners.
Using all 8 DIII ports, you can connect and control a total of 512 indoor units, at maxi-
mum.
WARNING
• Be sure to perform operation during power-off conditions.
Not doing so may cause an electric shock.
• To the extent possible, route the high-current cable of the power supply
cable and the low-current cable of the communication cable so that they
remain separate and are not side-by-side.
NOTE
The setting range of DIII address for the air conditioners controlled via the DGE601A52
is from “1-00” to “4-15”.
The DGE601A51 or iTM adds a DIII-NET port number to each address for identica-
tion. For example, “2:1-00” and “3:1-02”.
3.2.1 Terminals location and schematic wiring diagram
To connect the DIII-NET communication line, use the [F1] and [F2] terminals that are
located on the front face and indicated with [DIII]. These 2 terminals do not have polar-
ity.
An example of connecting more than 2 air conditioning devices is shown in the following
schematic connection diagram.
WARNING
Make sure that the wires that you connect to the [F1] and [F2] terminals are not
power wires.
Inadvertently connecting power wires to these terminals will result in a failure
of the air conditioner or DGE601A52.
