NOTE
• What’s a remote controller group?
A single remote controller can simultaneously control a maximum of 16 indoor units.
This capability is referred to as group control. A remote controller group is a group of
indoor units controlled under the same remote controller.

2.2.2 Requirements that must be met
Cable specica-
tions
• Cable type: 2-core vinyl-insulated vinyl-sheathed cable/vinyl cabtyre cable or 2-core
shielded cable
• Core thickness: 0.75mm² - 1.25mm²
• Terminal treatment: Use a round crimp-type terminal (M3.5) with insulating sleeve
Precautions • Do not use multicore cables with three or more cores.
• When using a shielded cable, connect only one end of each shield wire to the ground.
• The maximum wire distance must be kept to 1000 meters or less. The total wire length
must be limited to 2000 meters, except when using a shielded cable whose total wire
length must be kept to 1500 meters or less.
2.2.3 Precautions for using multiple centralized controllers
Equipment that controls multiple air conditioners is referred to as “centralized controller”.
DAIKIN’s product portfolio includes a wide range of centralized controllers suited to differ-
ent applications or target sizes, which can be used in combination to construct an optimal
air conditioning control system.
If two or more centralized controllers are used in combination in DIII-NET, you must estab-
lish a MASTER to SLAVE relationship among those controllers to prevent confusion. The
MASTER authority may be assigned to one controller only. The remaining controllers must
be set to SLAVE.
The intelligent Touch Manager 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.
• Where there is another MASTER intelligent Touch Manager or MASTER DGE601A51,
MASTER DGE601A52, MASTER DGE601A53, and it is connected in relations of main/
sub.
