Zoning / Averaging
The Vulcain 301C controller offers unique zoning
capabilities which permit the averaging and
comparison of multiple sensor readings. Zoning can
reduce operational costs by ensuring that localized
brief fluctuations registered at a single transmitter
do not activate relays. For example, a car idling in
a parking structure may locally increase a reading
at a nearby transmitter. Rather than activating a fan
as a result of the temporary localized fluctuation,
zoning can be used to limit relay activation until the
average reading for a zone exceeds a set-point.
This can reduce run time of fans, yielding savings in
both energy usage and wear and tear. The Vulcain
301C has the capacity to manage input from three
Modbus channels for up to 96 transmitters and up
to 50 wireless transmitters which can be associated
with up to 126 zones. Transmitters can belong to
an unlimited number of zones, providing maximum
operational and control flexibility.
Using an addressable RS-485 Modbus
communication protocol, the Vulcain 301C uses
daisy chain wiring requiring only 2 pairs of wires
to connect up to 96 transmitters on the 3 input
channels. This simplifies installation, in turn
lowering costs. The 301C’s zoning and averaging
abilities significantly reduce operational and
maintenance costs.
