Linkage
The i-Vu® Control System uses linkage to exchange data between the zone terminals and their air source to form
a coordinated HVAC system. The system's air source controller and zone controllers are linked so that their data
exchange can be managed by one zone controller configured as the VAV Master.
A VAV Master can have a maximum of 63 slave zone controllers reporting to it. A typical VAV Master has slave
controllers that are sequentially addressed beneath its own address on the same network. A VAV Master may also
have zones reporting to it that are not sequentially addressed, including those on other networks. These are
commonly referred to as Rogue zones.
A linked VAV system can be as simple as a single network with a VAV Master and slaves, or it can be as complex
as multiple networks with VAV sub-masters and slaves on other networks. See the following examples.
EXAMPLE #1: A simple network. The VAV Master exchanges data between the slave controllers and the AHU
controller. The linked controllers on the network must be sequentially addressed, and the VAV Master must have
the highest address.
EXAMPLE #2: The above network plus one slave controller (11) not sequentially addressed and one slave
controller on a different network.
