Fundamental of DIII-NET ED721208
4.2 Connection of Devices other than VRV
• You can connect adaptors and other devices (SkyAir adaptor, RA adaptor, Di/Dio units, etc.), which are not VRV, to
either indoor-outdoor connection or outdoor-outdoor connection.
• You cannot connect a chiller (which accommodates DIII-NET) to the same DIII-NET to which VRV, SkyAir, and RA
are connected.
- If you connect a chiller which accommodates DIII-NET to intelligent Manager III, divide the DIII-NET for VRV use
and for the chiller.
[Example]
• The maximum number of adaptors, except VRV indoor units, to be connected is 64 groups including VRV indoor
untis.
- One air-conditioner connecting adaptor (SkyAir adaptor, etc.) is counted as one group.
- One Di unit is counted as 8 groups.
- One Dio unit is counted as 4 groups.
- When the output of Dio unit is set to an instant contact point, one unit is counted as 2 groups.
* Regarding Di/Dio units, if you specify the number of groups to be connected to each unit, you can reduce the
number of groups connected to one unit.
