Precautions for using multiple centralised controllers

"Centralised controller" refers to the equipment (e.g. the DGE601A51) that controls
multiple air conditioners. Besides the DGE601A51, DAIKIN's product portfolio includes a
wide range of centralised controllers suitable for different applications or building sizes,
which can be used in combination to construct an optimal air conditioning control system.
If multiple centralised controllers are connected on the DIII­NET network, you must set the
"MAIN (MASTER)" and "SUB (SLAVE)" relationship for those controllers.
Set only one of those controllers as "MAIN (MASTER)", and the other controllers as
"SUB (SLAVE)".
The [DIII-1] and [DIII-2] switches
located on the front face of the DGE601A51. The
switches in the [ON] position set it as "MAIN" and
the switches in the [OFF] position set it as "SUB".
When installing multiple centralised controllers, set only the highest­priority controller as
"MAIN (MASTER)" and all other controllers as "SUB (SLAVE)" according to the follow­
ing order of priority.
