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

SimplyVAV

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
