NOTE: The sensor begins operation as soon as
the solar cell has charged the internal
energy storage device. Under normal
operating conditions this should be no
more than a few minutes. However, if the
sensor has been in dark storage for 36
months or more (deeply discharging the
energy storage), it may take several days
(depending on ambient light intensity)
for the circuit to become fully charged
and operational. Expose the sensor
to adequate light sources well before
installation as needed.
NOTE: Because the wireless sensors normally
transmit only several times per hour
to conserve power, allow at least 30
minutes for transmissions to be received
and all the relevant object values to be
updated when verifying normal operation.
NOTE: Sensors only transmit. They do not receive
signals from a gateway.
NOTE: See the data sheet for specications and
other information.

SELECT MOUNTING LOCATION
Installation Factors
Proper mounting location for wireless, solar-
powered sensors is far more critical than for
traditional wired sensors. When picking a location
to mount the sensor, the installer must be aware
of optimal placement regarding all three of the
following factors:
INTRODUCTION
Complete the following steps to mount a KMC
STW-6010, STW-6014, or THW-1102 wireless
sensor and connect it to a Conquest™ HPO-
9007NW or HPO-9007DW gateway.
KMC recommends charging up the sensors,
conguring them near the gateway, and testing
them (for signal strength, etc.) in the intended
locations BEFORE permanently mounting them.
Read carefully the following sections BEFORE
attempting installation.
STW-6010 and THW-1102 STW-6014

STW/THW Wireless Sensors Installation Guide 2918-019-02D
NOTE: Also consider the future use of the room
and avoid locations that may be later used
for ling cabinets, shelf units, or other
large obstructions that could block air
flow, light, and/or the RF signal.
Adequate RF Range/Path to the Gateway
For the RF signal, the maximum theoretical
straight-line distance between the gateway
and sensors is about 100 feet (30 meters).
However, in practice, the maximum distance will
be substantially reduced by obstacles in the
path, the shape of the room, sources of radio
interference, and placement/orientation of the
sensors and gateway!
See the application guide Planning for Wireless
Sensors Application Guide for important
information about proper placement of the
sensors and their gateway.
NOTE: To provide optimized placement
for all three sensor location factors,
repositioning the wireless gateway may
be necessary.
Adequate Light for Sensor Charging
To keep the sensor properly charged, mount the
sensor in an area with a minimum illumination
of 200 lux (e.g., typical light levels of interior
corridors, stairwells, storage rooms, or mechanical
rooms) for three to four hours every day. The
light source can be daylight (preferred) or articial
(dependent on type).
Articial lighting sources are not as effective in
keeping sensors charged as indirect daylight
because of spectrum and intensity differences.
LED lights (although energy efcient) are even less
effective in charging sensors than incandescent
or fluorescent lights. In an interior room that
has LED (only) lighting, a sensor should have
a battery installed as a backup. See (Optional)
Install Battery Backup on page 3.
Avoid recessed areas that are not sufciently
illuminated throughout the day. Avoid mounting
the sensor angled away from light sources. The
long-term illumination should not exceed 1000
lux (equivalent to outdoors on an overcast day).
The sensors can be mounted with the solar cell
toward a window but not in direct sunlight at any
time of the day since direct sunlight will give false
temperature values.
If fully charged, the sensor can transmit normally
for about four days in total darkness (without the
backup battery). If longer periods of darkness may
occur, install a battery as a backup. See (Optional)
Install Battery Backup on page 3.
Accurate Temp/Humidity Measurement
Install the sensor on an inside wall where it
can sense the average room temperature/
humidity and be away from direct sunlight, heat
sources, windows, air vents, and air circulation
obstructions (curtains, furniture, etc.).
See the Room Sensor and Thermostat Mounting
and Maintenance Application Guide for additional
mounting and troubleshooting information for
measuring temperature and humidity.
REMOVE BACKPLATE
To permanently mount the sensor, the cover must
be removed. The sensor cover is held to the black
backplate by three, small, round pegs that t in
the holes of the sensor body. The bottom peg is a
spring tab and snaps into the center bottom hole.

3. Note the Learn pushbutton on the other
side of the sensor. The button may be on
the “top” of the switch body facing you or
on the side, depending on the model. Use
a small screwdriver to push the button for
device discovery and immediate transmission
updates.
NOTE: The antenna is a wire whip looped under
the cover for 902 MHz models and is a
helical wire for 868 MHz models.
MOUNTING
NOTE: KMC recommends conguring the
sensors near the gateway and testing
them (for signal strength, etc.) in the
intended locations BEFORE permanently
mounting them.
1. Locate the sensor identication number on the
label that is inside of the sensor body.
2. Record the location of the sensor and
identication number on the system plans.
3. Using the backplate as a template, drill two
holes for mounting screws 1-13/32 inches
(35.6 mm) apart. For the supplied screws, drill
7/64 inch (3 mm) holes.
NOTE: For drywall, plaster, or concrete
mounting surfaces, plastic anchors are
recommended. If anchors are used, adjust
the size of the holes for the anchor.

4. With the plastic tab button on the bottom,
attach the backplate to the wall using two
#6self‑threading screws.
5. Place the top of the cover over the top of the
backplate and gently push the bottom part of
the cover toward the wall until the cover snaps
onto the backplate.
OPERATION
The sensor will begin operation as soon as the
solar cell has charged the internal energy storage
device. Under normal operating conditions this
should be no more than a few minutes with
adequate illumination. However, if the sensor
has been in dark storage for 36 months or more
(deeply discharging the energy storage), it may
take several days (depending on ambient light
intensity) for the circuit to become fully charged
and operational. Expose the sensor to adequate
light sources well before installation as needed.
TROUBLESHOOTING
Erratic Temperature Readings
• Reposition the sensor. See the Mounting for Op-
timal Temperature Sensing section in the Room
Sensor and Thermostat Mounting and Mainte-
nance Application Guide.
Sensors Not Discovered
• Bring the sensor close to the gateway and press
the Learn button. See Conguration on page 3.
• Check that the sensor and gateway are the same
frequency (models DW vs. NW).
• Check that controller rmware and software tool
versions are current. See the Software and Firm-
ware Requirements section in the HPO-9007
Series Gateways Installation Guide.
• Allow adequate time for sensor to charge or add
the optional backup battery to the sensor. See
(Optional) Install Battery Backup on page 3.
Sensor Signals or Values Erratic or Lost
• Check area for new or changing obstructions.
• Add a battery backup to the sensor.
• Reposition the sensor.
• Add a repeater or an additional gateway. See
the Adding Gateways or Repeaters to Extend
Coverage section in the Planning for Wireless
Sensors Application Guide.
NOTE: The AV in a KMC Conquest controller
associated with a sensor’s value
maintains the last received value until it is
refreshed by a new signal.
NOTE: If the HPO-9007 is momentarily
unplugged or the controller momentarily
loses power, sensor values will
temporarily return to 0 until updated
by a later sensor transmission. The
sensors may also need to be discovered
again to see the icon and EEP in the
Gateway Sensor List section of the
EnOcean Sensor Port object. See the Add
Sensors section in the HPO-9007 Series
Gateways Installation Guide. (Restarting
the controller through software may also
cause a temporary loss of values but
should not require a new discovery of the
sensors.)
NOTE: Creating an alarm for a lost signal event
may be desired. For example, if the time
since the last received transmission
exceeds 3600 seconds (at least two
missed signals), an alarm is generated.
NOTE: Some lost signals may be self-correcting,
such as a sensor in a darkened ofce
during a long, holiday weekend that
recharges the next open business day.
Setpoint Adjustment Does Not Work
• Check the conguration. See Conguration on
page 3.
• Check the Control Basic programming.
• Verify that the objects are not being overwritten
by other sources.
• Check the HVAC/BAS system.

Wrong Values
• Check the conguration. See Conguration on
page 3.
• Allow enough time for sensor transmissions.
NOTE: Because the wireless sensors normally
transmit only several times per hour
to conserve power, allow at least 30
minutes for transmissions to be received
and all the relevant object values to be
updated when verifying normal operation.
Other Issues
• If an HPO-9001 distribution module is being
used on the controller, see the “Use of HPO-9001
Distribution Module” section in the HPO-9007
Series Gateways Installation Guide.
• Contact KMC Controls for assistance.
MAINTENANCE
Careful installation will help ensure long-term
reliability and performance.
To maintain accurate temperature and humidity
sensing, remove dust as necessary from the
ventilation holes in the top and bottom of the
cover.
To clean the cover, use a soft, damp cloth (and
mild soap if necessary). Do not spray any liquids
on the cover.
Replace the optional lithium battery every three
years or as needed by actual use.*
*NOTE: Factors that shorten battery life include:
• Installation in interior spaces with only
articial light (which charges sensors
less efciently than indirect daylight).
• Lengthy periods of darkness (which
increases the reliance on the battery).
• Adding setpoint adjustment or humidity
to a temperature sensor (which requires
more power).
• Frequent changes (beyond their respec-
tive thresholds) in measured tempera-
ture, humidity, or setpoint values (which
makes transmissions more frequent).
