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.

(OPTIONAL) INSTALL BATTERY BACKUP

CR1225

Battery

Holder

Optionally, a single CR1225 lithium battery can be

installed as a power backup for locations without

sufcient light to maintain sensor operation.

1. Position the battery with the plus (+) symbol

visible.

2. Slide the battery into the battery holder.

NOTE: If replacing the battery, rst carefully

push out the old battery using a narrow

screwdriver blade through the slots in the

other side of the holder.

CONFIGURATION

1. See the HPO-9007 Series Gateways

Installation Guide for instructions on

conguring the sensors in the software.

2. Note the sensor identication number

(identifying that unique sensor) on a label that

is inside of the sensor body.

Button

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.
