The VLT® HVAC Drive is
hooked upon your net
The VLT® HVAC Drive integrates and
communicates seamlessly with all
HVAC devices, mastered by Building
Management Systems via the fi eldbus.
HVAC-specifi c features make it
economical, fl exible and user-friendly
and make HVAC operation simple.
Improve system performance
VLT® HVAC Drive uses limited network
bandwidth, and it requires less
resources in the DDC controller due to
the support of alarm and event
notifi cation.
This can reduce traffi c by more than
50% compared to other drives.
With VLT® HVAC Drive it is possible to
read all the inputs and control all the
outputs on I/O options.
This means that when integrating a
VLT® HVAC Drive into the control
system it is possible to save by
requiring fewer physical I/O points.
Detailed information about
warnings and alarms
VLT® HVAC Drive has points giving
detailed information about alarms and
warnings. DDC controllers can
monitor these and see when an alarm
or warning occurs and why it
occurred.
VLT® HVAC Drive comes with an
embedded BACnet protocol that
makes it suited for most smaller
plants.
For larger plants, more system
performance is required.
Have BACnet your way
The VLT® BACnet option is a plug-and-
play solution that optimizes the use of
VLT® HVAC Drive together with
building management systems using
the BACnet® fi eldbus.
VLT® HVAC Drive has objects defi ned
to accept 3 separate feedbacks
transmitted over BACnet.
This option makes it easy to control or
monitor points required in typical
HVAC applications.
Listed by BTL
The option has passed comprehensive
and long-lasting tests at the BTL
laboratories, which ensures that the
function will work together with any
other BLT-listed equipment.
