Description
The SimplyVAV series of controllers are an easy and
unique approach to operating a wide variety of VAV
terminal units. The integrated actuators, internal
airow sensors, and wide variety of application
programs make these BACnet Application
Specic controllers ideal for either new or retrot
installations.
Easy to install Just mount the controller, wire it
to a 24 volt transformer, and then connect airow
and temperature sensors. A SimplyVAV controller
automatically detects sensors as they are connected
without special programming or soware tools.
Simple, menu driven setup The controllers feature
simple, menu driven setup choices. No special
programming skills or soware tools are required
to choose applications, enter setpoints, set network
addressing, and balance airow. All options can
be set by using only an STE-8001 sensor which
can be installed as the permanent room sensor or
temporarily connected as a technician’s service tool.
New or retrot applications The SimplyVAV
controllers are ideal for new installations or
upgrades of older, less ecient controllers.
 Staged, modulated, oating, or time proportional
reheat
 Series or parallel fan control
 Single or dual duct application
Native BACnet All models are BACnet Application
Specic Controllers that are ready to connect to a
BACnet MS/TP network. Device instance, MAC
address, and baud rate are set from an STE-8001
without special soware.
Easy system integration For SimplyVAV
installations that are part of a BACnet building
automation system, the controllers provide system
diagnostic indicators. Through the MS/TP network,
the controllers signal demands for higher static duct
pressure, cooler or warmer supply air, and when to
start air handler units.
