La Crosse Alerts™ Remote Water Detector &

Temp. & Humidity Monitor w/ Early Warning Alerts

Model: D012.104.E1

Did you know that frozen pipes that crack and burst damage a
quarter million properties each year? The best defense against
costly water damage to your home, business or vacation rentals

is the La Crosse Alerts™ Remote Water Detector with early

warning alerts to notify you of a water leak before it has time to
cause extensive damage.*

Use your smartphone, tablet or computer to monitor for water
leaks and high or low temperature and humidity levels that could
lead to frozen pipes and mold growth.*

Water damage can originate in almost any room: frozen pipes,
broken pipes, broken dishwasher hose or leakage, washing
machine overflow, leaking roof, basement leaks, foundation
cracks, plumbing leaks, sump pump overflow and leaks from
bad weather such as snow, rain or floods.*

The good news is that water damage is a costly problem that
you can prevent with text and e-mail alerts from anywhere with
Internet access.*

Wall-mount the water detector, or use the included tabletop
stand and place the H2O sensor on the floor to activate the
wireless alert system when it becomes wet.* Alerts are sent
when pre-set temperature and humidity levels are exceeded,
water is detected and when the batteries are low or the
connection is lost, saving you from having to stop and check.*

MONITORING OPTIONS

 Home, second home, office or rental property
 Kitchens, baths, laundry & pool rooms
 Utility sinks, sumps & water heaters
 Basements, garages & attics
 Near aquariums & terrariums

gateway(not included) to monitor additional areas

 200 Ft wireless range

(B) D000.104 Water Sensor on 6 Ft. Detachable Cable:

Detects the presence or absence of water which is displayed on
the LCD: WET (H20) / DRY status (Channel 2)

The detachable H20 (water) sensor detects water.

 **Attach it to the main sensor case and place the

sensor on the floor or other area you wish to monitor
for WET/DRY conditions.

 **The official D000.104 H20 Sensor can be plugged

into the sensor at any time without resetting.

HOW IT WORKS

 The wireless sensor transmits water status & temperature

and humidity measurements to a La Crosse Alerts™
Gateway (not included) within a 200 Ft. (60.96m) wireless
range.*

 The Gateway (not included) connects to your existing

network router and uses your high-speed Internet
connection to upload collected measurements to your own
account at www.lacrossealerts.com.*

 Once the Gateway (not included) and temperature and

humidity sensor are activated on your account, you can
monitor sensors online from a smartphone, tablet or
computer, and set up custom e-mail/text alerts*.

PREPARE FORSETUP

1. Begin the set up near your existing network router and a
computer with high-speed Internet access.

2. Unpack package contents and insert the H2O sensor cord
into the TX70U-IT water detector (see diagram 1).

SELECT A LOCATION TO MOUNT WATER

DETECTOR

Select a location…

 Select a location that protects the sensor from water.

The sensor case is water resistant, not water proof.

 Select a location within range of the Internet Gateway (not

included) (see “IMPORTANT SETUP & OPERATION
NOTES”).

 Place H2O sensor on the floor where you choose to monitor

for water and secure the water detector case in an area that
is protected from water. Once activated, you can view the
temperature/ humidity and H2O/Dry readings on the LCD.

 Mount the sensor once it is activated (see “SETUP AND

ACTIVATION”).

 IMPORTANT! Test the sensor in the desired mounting

location for at least 1 hour to ensure good reception with

the Internet Gateway (not included). Confirm your readings at
www.lacrossealerts.com before permanently mounting. Move

the sensor closer to the Internet Gateway (not included)
if the signal is lost or not received.

MOUNT TO WALL WITH SCREWS

1. Remove the mounting bracket from the
water detector.

2. Place the mounting bracket over the
desired location.

3. Mark mounting surface with a pencil
through the 2 holes of the bracket.

4. Screw mounting bracket onto surface and
tighten screws to bracket.

5. Insert the water detector into the bracket.

TABLE STAND AND OTHER MOUNTING OPTIONS

Attach the mounting bracket to the bottom or on
the top of the water detector and place it on any flat
surface.

Note: Before permanently mounting,
TEST the sensor in the selected location for at
least 1 hour to ensure good reception.

PLACEMENT OF THE H2O SENSOR

The H2O sensor should be placed on the dry floor or against the
wall near your foundation, water heater, sump, plumbing,
washer aquarium, or dish washer etc. to monitor for leaks.

FLOOR:

Place the H2O sensor (circuit board down)
on the dry floor within range of the water
detector with temperature / humidity that is
mounted on the wall or standing on a table.
Note: The water detector will sit 1/8 inch
from the floor in this position.

WALL:

Place the H2O sensor against the wall with
the edge touching the floor within range of
the water detector with temperature/humidity
that is mounted on the wall or standing on a
table.

 The H2O sensor can be secured to the floor or wall with the

included screws & anchors or with two-sided tape (not
included).

 Secure the 6 ft. H2O sensor cable to avoid tripping hazards:

Loosely coil and secure the extra cable with a twist tie.

CLEANING THE H2O SENSOR

Routine cleaning of the H2O
sensor is recommended to
ensure proper operation.

Use clean water and a soft cloth to clean dirt and debris from
the circuit board of the H2O sensor.

Note: When using two-sided tape, replace the tape after
cleaning the H2O sensor to maintain adhesiveness.

IMPORTANT SETUP & OPERATION NOTES

 The water detector with temperature and humidity sensor

case should be placed in a dry, shaded area. Please avoid a
location with direct sun, as that will cause incorrect readings.

 Fog and mist will not harm the temperature and humidity

sensor but direct rain must be avoided.

 Note: Exposing the water detector and temperature and

humidity sensor case to extreme humidity may temporarily
disrupt data. The temperature and humidity sensor case
reads humidity, but should not be submerged in water. Attach
the H20 sensor on 6 ft. detachable cable to detect water on
floor or other location.

 The H20 sensor on 6 ft. cable is not for use in a pool or hot

tub where chemicals may cause malfunction.

 The water detector and temperature and humidity sensor has

a wireless range of 200 feet (60.96 m). Keep in mind that the
200 ft. range equates to open air with no obstructions, and
that radio waves DO NOT curve around objects. Actual
transmission range will vary depending on what is in the path
of the signal. Each obstruction (roof, walls, floors, ceilings,
etc.) will effectively cut signal range in half.

 Metal, stucco, and some types of glass can reduce signal

range by as much as ¾ or more, compared to the ½
reduction typical of most obstructions. It is possible to
receive a signal through these materials, however maximum
range will be reduced due to their tendency to absorb or
reflect a much larger portion of the sensor’s signal.

 The water detector and temperature and humidity sensor

measures and updates the temperature and humidity on the
LCD every 12 seconds.

Note: The new measurement is reported to your account at
intervals that you select using your online account.

BATTERY REPLACEMENT

1. Remove the battery cover by sliding the cover down.

2. Observing the correct polarity install 2-AAA batteries. The
batteries will fit tightly (to avoid start-up problems make sure
they do not spring free).

3. Do not mix old and new batteries.

4. Do not mix alkaline, lithium, standard or rechargeable
batteries.

5. Replace the battery cover by sliding upwards and check that
it is securely fitted.

LOW BATTERY INDICATOR

 Low battery icon appears on LCD when batteries are low.
 You will receive an e-mail or mobile text message alert when

the battery power of the sensor is low. Change the batteries
immediately.

Note: The LED light turns ON briefly after changing batteries.
The LED light turns OFF when not needed to save battery
power. The previously stored information in the temperature and
humidity sensor will not be affected or cancelled while you
change the batteries.

MAINTENANCE AND CARE

 Avoid extreme temperatures, vibration and shock.
 Clean the water detector and H20 sensor with a soft, damp

cloth. Do not use solvents or scouring agents.

 Do not submerge the water detector case in water.
 Avoid kinking the 6 ft. H20 sensor cable.
 Secure the 6 ft. cable to avoid tripping hazards.
 Immediately remove all low powered batteries to avoid

leakage and damage.

 Opening the casings invalidates the warranty. Do not try to

repair the unit. Contact La Crosse Technology® for repairs.
