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

Setting the rotation limits
SimplyVAV controllers are manufactured for a damper that rotates 90 degrees from open to
close. If the VAV damper is not a 90 degree damper, set the rotation limits to 45 or 60
degrees before mounting the controller.
Caution
Before setting the rotation limits on the controller, refer to the
damper position specifications in the VAV control box to which
the controller will be attached. Setting rotation limits that do not
match the VAV damper may result in improper operation or
equipment damage.

Revision H 13

To set the rotational limits, do the following
1Turn the controller over so you have access to the back.
2Manually rotate the actuator fully clockwise as viewed from the back.
3Remove the stop screw from its storage location and clean any debris from the
threads.
4Insert the screw into the correct stop position hole.
5Tighten the screw only until the head touches the plastic in the bottom of the recess.
Mounting on a VAV terminal box
Mount the controller inside of a metal enclosure. To maintain RF emissions specifications,
use either shielded connecting cables or enclose all cables in conduit.
Mount the controller directly over the damper shaft. A minimum shaft length of 2.0 inch
(51mm) is required.
Note: SimplyVAV controllers are designed to directly mount to 3/8 to 5/8inch (9.5to16mm)
round or 3/8 to 7/16 inch (9.5to11 mm) square damper shafts.

direction that opened the damper. Turn the hub until it reaches a rotation limit.
3Loosen the nuts on the V-bolt until the damper shaft can fit through the collar.
4Place the controller over the damper shaft.
5Finger tighten the nuts on the V-bolt to position the shaft in the drive hub.
6Center the mounting bushing in the mounting tab and fasten it with a #8 sheet metal

application. Follow the instructions supplied with the sensor for installation.
lFor DAT limiting and reheat, install the sensor in the airflow after the reheat unit. See
the topic, Advanced options on page 33 to enable discharge air temperature control.

lUse a Class–2 transformer of the appropriate size to supply power to the controller.
lKMC Controls recommends powering only one controller from each transformer.
lDo not run 24 volt, AC power from within an enclosure to external controllers.
Connect the 24 volt AC power supply to the power terminal block on the lower right side of
the controller. Connect the ground side of the transformer to the ground terminal and the
AC phase to the phase terminal. Power is applied to the controller when the transformer is
connected to power.
