3. Group Addressing Types for Indoor Units
A group address is a unique address that assigned manually to an indoor unit or a group of indoor units on the DIII-
Net system during the VRV commissioning process. Up to 64 group addresses can be assigned in one DIII-Net
system. Group addresses are as follows: 1-00 to 1-15, 2-00 to 2-15, 3-00 to 3-15 and 4-00 to 4-15. A remote control
group consists of 1 to 16 indoor units daisy-chained together via P1P2 connections. The unit# is used to identify
the indoor unit within a group of indoor units, unit#0 is the indoor unit responsible for receiving commands from
the iTM, and relay the data to the other units in the group.
