Secti on 1: About the controll er s
This section provides a description of the SimplyVAV series of controllers. It also
introduces safety information. Review this material before selecting, installing, or
operating the controllers.
The SimplyVAV series of controllers are an easy and unique approach to operating a wide
variety of VAV terminal units. The integrated actuators, internal airflow sensors, and wide
variety of application programs make these BACnet Application Specific controllers ideal for
either new or retrofit installations.
The controllers feature simple, menu driven setup choices when used with a SimplyVAV
digital sensor. No special programming skills or software tools are required to choose
applications, enter setpoints, set network addressing, and balance airflow. 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.
All models are BACnet Application Specific 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
sensor without special software.
BAC-8001 Model BAC-8001 is supplied with inputs, outputs, and sequences of operation for
the following functions.
lSingle duct heating and cooling VAV
lAutomatic heating/cooling changeover including morning warmup
lOccupancy setback—requires STE-8201
lSystem diagnostic indicators
lAirflow balancing
BAC-8005 and BAC-8205 Models BAC-8005 and BAC-8205 are supplied with inputs,
outputs, and sequences of operation for the following functions.
lSingle duct heating and cooling VAV
lModulating, floating, time proportional, and staged reheat
lSeries and parallel fan control
lAutomatic heating/cooling changeover including morning warmup
lDischarge air temperature limiting
lOccupancy setback—requires STE-8201
lActuator position feedback for true damper positioning (BAC-8205 only)
lSystem diagnostic indicators
lAirflow balancing

Revision H 5

BAC-8007 Model BAC-8007 is supplied with inputs, outputs, and sequences of operation for
the following functions.
lDual-duct VAV heating and cooling
lOccupancy setback—requires STE-8201
lSystem diagnostic indicators
lAirflow balancing
