S e c t i o n 1 : A b o u t th e c o n t r o ll e r 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 without special software.

who install, operate, and service the equipment as well as protection of the
equipment itself. To promote safety, we use hazard alert labeling in this
manual. Follow the associated guidelines to avoid hazards.
Danger represents the most severe hazard
alert. Bodily harm or death will occur if danger
guidelines are not followed.
Warning represents hazards that could result in severe
injury or death.
Caution indicates potential personal injury or equipment or
property damage if instructions are not followed.

Section 2: Installing the controllers SimplyVAV
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.
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.
Illustration 2–1 Controller rotation limit selections
To set the rotational limits, do the following
1. Turn the controller over so you have access to the back.
2. Manually rotate the actuator fully clockwise as viewed from the back.
3. Remove the stop screw from its storage location and clean any debris
from the threads.
4. Insert the screw into the correct stop position hole.
5. Tighten the screw only until the head touches the plastic in the bottom

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.

Illustration 2–2 Controls and indicators
Mount the controller as follows:
1. Manually rotate the damper on the VAV box to the fully open position.
2. On the controller, press the gear clutch button and rotate the drive hub
in the same direction that opened the damper. Turn the hub until it
reaches a rotation limit.
3. Loosen the nuts on the V-bolt until the damper shaft can fit through the
collar.
4. Place the controller over the damper shaft.
5. Finger tighten the nuts on the V-bolt to position the shaft in the drive
hub.
6. Center the mounting bushing in the mounting tab and fasten it with a #8
sheet metal screw.
7. Evenly tighten the V-bolt nuts on the drive hub to 30-35 in-lbs.

Connecting power
The controllers require a 24 volt, AC power source. Use the following
guidelines when choosing and wiring transformers to the controller.
Use a Class–2 transformer of the appropriate size to supply power to the
controller.
KMC Controls recommends powering only one controller from each
transformer.
Do 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.

This topics in this section are advanced topics for control technicians and
engineers.
The configuration functions that are accessible through an STE-8000 series
sensor are all of the values and settings that are entered during the
installation and commissioning of a VAV terminal unit. Typically, these
functions do not change after the installation and commissioning process.
To set up the configuration functions, you will need the following items and
information.
Details about the VAV terminal unit including the configuration for fans
and reheat.
An STE-8001 or STE-8201 to use as a configuration tool.
The building automation system plans for controllers connected to a
