La Crosse Technology TX22U User Manual

TX22U -Wireless 915 MHz Thermo-hygro

transmitter

The TX-22U thermo-hygro transmitter measures the outdoor
temperature and humidity and also transfers the wind and rain data to
the weather station.

INVENTORY OF CONTENTS

1. One TX22U Thermo-hygro transmitter

2. Mounting hardware

3. Instruction manual and warranty card.

ADDITIONAL EQUIPMENT (not included)

•

Two fresh AA 1.5V batteries for the remote Thermo-hygro
transmitter, which in turn powers the wind speed sensor and the
rainfall sensor (No need to insert batteries to Wind and Rain
sensor.)

Important Notes on Set-up and Operation

• The Thermo-hygro transmitters both the source of power for both
outdoor sensors and source of transmission for all remote sensor
data.

• The Thermo-hygro transmitter should be placed in a dry, shaded
area. Avoid direct sun, as that will cause incorrect readings.

• Fog and mist will not harm your Thermo-hygro transmitter but
direct rain must be avoided.
The thermo-hygro sensor has a range of 330 feet. Keep in mind
that the 330 feet is i n 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, thick trees, etc.) will
effectively cut signal range in half.

Example: A wireless weather station with a 330 feet range is
mounted on an interior wall, so that the signal has to pass
through one interior wall, one exterior wall, and across the 10
feet width of the room between the 2 walls. The first wall will
reduce the range to 165 feet, and the second wall will reduce the
range to 87 feet. Factoring in the 10 foot room, this leaves a
maximum of 77 feet of remaining signal range.

This allowance is typically enough for a frame wall with non­metallic siding; however certain materials can reduce range even
further. Metal siding, 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 much less due to their tendency to absorb or reflect a much
larger portion of the sensor’s signal.

• The Thermo-hygro transmitter transmits a signal about every 4.5
seconds. After the batteries have been installed, the indoor
weather station will search for the signal for the duration of few
minutes. If there is no temperature or humidity reading in the
OUTDOOR LCD or wind speed in the WIND SPEED LCD after 5
minutes, user shall make sure the units are within range of each
other, or repeat the battery installation procedure.

• If a button is pressed before the indoor weather station receives
the signal from the Thermo-hygro transmitter, you will need to
follow the battery installation procedure again.

First user shall unwind the cables of the Rain and the Wind sensors.
Connect the Rain and the Wind sensors to the Thermo-hygro
transmitter by plugging the connector heads of the two sensors into
the appropriate sockets of the Thermo-hygro transmitter. Be sure they
“click” into place.

Battery Installation
REMOTE Thermo-hygro transmitter

1. Remove the mounting bracket and humidity hood.

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

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

4. Replace the battery cover by sliding upwards. Be sure battery
cover is on securely.

5. Replace the humidity hood.

Weather Station

1. Then insert the batteries into the Weather Station. Once the
batteries are installed, all segments of the LCD will light up
briefly and a short signal tone will be heard. It will then display
the time as 12:00, the date as 1.1.05, the weather icons, and air
pressure value. "- - -" will be shown for outdoor data.

2. Afterwards, the Weather Station will start receiving data from
the transmitter. The outdoor temperature, humidi ty wind chill
and wind speed should then be displayed on the Weather
Station. If this does not happen after 30 seconds, the batteries
will need to be removed from both units. You will have to start
again from step 1.

3. You may then check all cables for correct connection and all
components for correct function by manually turning the wind­gauge, moving the weather-vane, tilting the rain sensor to hear
the impact of the internally moving seesaw, etc.

4. Time and dat e shall be manually set.

5. After the Weather Station has been checked for correct function
with regard to the above points and found fit, the initial set up of
the weather station system is finished and the mounting of the
system components can take place. It must be ensured
however that all components work properly together at their
chosen mounting or standing locations. If e.g. there appear to
be problems with the 915 MHz radio transmission, they can
mostly be overcome by slightly changing the mounting locations.

Note:

The radio communication between the receiver and the transmitter in
the open field reaches distances of max 330 fe et (100 meters),
provided there are no interfering obstacles such as buildings, trees,
vehicles, high voltage lines, etc.

6. Radio int erferences created by PC screens, cordless phones,
radios or TV sets can in some cases entirely cut off radio
communication. Please take this into consideration when
choosing standing or mounting locations.

Note:

•

After batteries are installed in transmitter, user shall also power
up the Weather station to receive the signal from the transmitter
as soon as possible. If the weather station is powered after
more than 5 hours the transmitter is powered, the weather
station will never receive signal successfully from this
transmitter. In this case, user will need to reinstall the batteries
from the transmitter to redo setting-up procedures.

•

Detailed Set up procedures of the Weather Station, the Relay
Transmitter, the Rain sensor and the Wind Sensor refer to the
main operation manual of WS- 1610.

MOUNTING

THE THERMO-HYGRO TRANSMITTER

The Thermo-hygro transmitter can be mounted in several ways:

• With the use of screws

• Using adhesive tape (Use Tape as a positioning tool only.)

• Using nylon straps

MOUNTING WITH SCREWS

1

1) Remove the mounting bracket from the Thermo-hygr o
transmitter .

2) Place the mounting bracket over the desired location. Humidity
cap must be in the upright position.

3) Through the two screw holes of the bracket, mark the mounting
surface with a pencil.

4) Screw mounting bracket onto the mounting surface. Ensure
that the screws are tight against the bracket.

5) Insert the Thermo-hygro transmitter into the bracket.

MOUNTING WITH ADHESIVE TAPE

Two-sided tape is included only as a positioning tool while you test for
signal reception and properly position your sensor. Tape only should
not be used for mounting as the sensor may fall. Please secure with
screws or nylon straps.

MOUNTING WITH NYLON STRAPS

1) Remove the mounting bracket from the Thermo-hygr o

2) Place two nylon straps through the slots on the mounting

3) Place the Thermo-hygro transmitter in your desired mounting

4) Fasten the two nylon straps securely around the mounting

MAINTENANCE AND CARE

• Extreme temperatures, vibration, and shock should be avoided to

prevent damage to the units.

• Clean displays and units with a soft, damp cloth. Do not use

solvents or scouring agents; they may mark the displays and
casings.

• Do not submerge in water.

• 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.
