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.
