1. Precautions for using multiple centralized controllers.
a. The “centralized controller” refers to the equipment (e.g. the
iTM
) that controls multiple
indoor units. In addition to the
iTM
, the Daikin product portfolio includes a wide range of
centralized controllers suitable for different applications or building sizes. These controllers
can be used in combination to construct an optimal air conditioning control system.
b. If multiple centralized controllers are connected on the DIII-Net network, set a MASTER and
SLAVE relationship for those controllers.
c. Assign only one of the controllers to MASTER, and other controllers to SLAVE.
d. The iTM is set to MASTER by default. Change the setting to SLAVE in the following cases:
• Interface for use in BACnet® is installed in parallel.
• Interface for use in LONWORKS is installed in parallel.
• If another
iTM
or
iTM
Plus Adaptor is assigned to MASTER.
