SECTION 1
Introduction to STE-8000 sensors
Models STE-8001 and STE-8201 are wall-mounted, temperature sensor for use
with Titus BAC-8000 series VAV controllers. Key features include the following:
Integrated operator interface ready to use with BAC-8000 series VAV
controllers
Large LCD display
Simple three-button interface
Continuously displays temperature and time
Separate password protection for user and commissioning functions
Use as a service tool to set up BAC-8000 series VAV controllers
Optional motion sensor to detect space occupancy
Note
The STE-8000 series sensors will display time if the controller to which they are
attached have been synchronized with system time within the previous 24
hours.

Safety
considerations
Danger
Danger represents the most severe hazard alert. Bodily harm or death will
occur if danger guidelines are not followed.
Warning
Warning represents hazards that could result in severe injury or death.
Caution
Caution indicates potential personal injury or equipment or property damage
if instructions are not followed.
Note
Notes provide additional information that is important.
Detail
Provides programing tips and shortcuts that may save time.
Titus assumes the responsibility for providing you a safe product and safety
guidelines during its use. Safety means protection to all individuals 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.

SECTION 2
Installing STE-8000 sensors
This section provides important instructions and guidelines for
installing the STE-8000 series sensors. Carefully review this
information before installing the controllers.
Installing the sensors includes the following topics that are covered in this
section.
Planning for motion sensing on page 9
Rough-in preparation on page 10
Installing the sensors on page 10
Maintenance on page 11
Planning for
motion sensing For STE-8201 only—Mount the STE-8201 sensor on a wall that will have an
unobstructed view of the typical traffic in the coverage area. When choosing a
location, do not install the sensor in the following areas.
Behind curtains or other obstructions
In locations that will expose it to sunlight or heat sources
Near a heating/cooling duct.
For details on the coverage pattern, see Specifications on page 6.
The effective detection range is approximately 10 meters or 33 feet. Factors that
may reduce the range include:
The difference between the surface temperature of the object and the
background temperature of the room is too small.
Object movement in a direct line toward the sensor.
Very slow or very fast object movement.
Obstructions as shown in the illustration Typical motion sensing coverage area
on page 9.
Illustration 2-1 Typical motion sensing coverage area

Installing STE-8000 sensors
Rough-in preparation
8
False detections may be triggered by:
The temperature inside the detection range suddenly changes because of
the entry of cold or warm air from an air-conditioning or heating unit.
The sensor being directly exposed to sunlight, an incandescent light, or
other source of far-infrared rays.
Small animal movement.
Rough-in
preparation Complete rough-in wiring at each sensor location prior to sensor installation.
This includes the following.
Routing the connecting cable from the sensor to a controller.
If required, install the appropriate backplate. See Accessories on page 6for
model numbers.
Connect the STE-8000 series sensor to a controller with a standard Ethernet cable
with RJ-45 connectors on each end. Maximum cable length is 75 feet (22.9
meters). Plenum-rated preassembled cables are recommended.
Installing the
sensors To install the sensor on a backplate, do the following:
1. Turn the Allen screws in the base of the NetSensor clockwise until they
clear the cover. Swing the sensor away from the mounting base to remove
it.
2. Route the Ethernet cable through the mounting base.
3. Fasten the mounting base directly to a 2 x 4 inch outlet box or a backplate
with the Allen screws toward the floor.

4. Insert the Ethernet cable coming from the base into the sensor.
5. Place the top of the sensor over the top of the mounting base and swing it
down over the Allen screw brackets. Be careful not to pinch any wiring.
6. Back the Allen screws out of the brackets until they engage the sensor cover
and hold it in place.
Maintenance Remove dust as necessary from holes in top and bottom. Clean the display with
soft, damp cloth and mild soap.

SECTION 3
User functions
This section covers topics for the end user in a facility.
User functions are limited to changing the occupied temperature setpoints from
the STE-8000.
Operating the
STE-8000 The functions are accessible through an STE-8000 series sensor. The functions are
entered or changed using the buttons and display on the front of the STE-8000.
Pressing either the up button or down button changes a selection,
setting, or value.
Pressing the setpoint button saves the setting or value. Typically saving
an entry also advances to the next display.
Note
The STE-8000 series sensors will display time if the controller to which they are
attached have been synchronized with system time within the previous 24
hours.

SECTION 4
Commissioning functions
This topics in this section are advanced topics for control technicians
and engineers.
The commissioning functions that are accessible through an STE-8000 series
sensor are 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 commissioning functions, you will need the following:
Information about the VAV terminal unit including the configuration for
fans and reheat
The installation and operation manual supplied with the controller to
which the STE-8000 series sensor is connected.
The building automation system plans.
Users may change the occupied heating and cooling setpoints without accessing
the commissioning functions. This procedure is covered in User functions on
page 13.
Note
The instructions for commissioning functions cover all of the functions that an
STE-8000 sensor can set up in the BAC-8000 series of controllers. Not all
functions are available on every model of controller. Consult the installation
and operation manual supplied with the controller to verify the functions and
options that are available.
