Batteries

Explanation: Many problems are resolved with fresh batteries of the appropriate

voltage. Many items sent in under warranty, work when tested with fresh batteries.

Batteries manufactured this year will have an expiration date 10 years (or more) in

the future. Battery technology has improved and batteries will maintain voltage

longer in storage. However, the environment the batteries reside in for the 10 years

can deplete the power.

Use Alkaline or Lithium batteries in the remote sensor.

A minimum voltage of 1.48V for each battery is necessary for proper

performance.

Use batteries dated at least six years in advance of the current year. Batteries

dated earlier than six years from now may still work, but may be unstable in

performance.

Good name brand batteries make less noise, which reduces the chance of RF

(radio frequency) interference from the battery compartment.

Weather Station Factory Restart

Explanation: The factory restart returns the weather station and remote sensor to

an “out-of-the-box” default state and often resolves an issue.

Factory Restart:

1. Remove batteries from remote sensor and weather station.

2. Press one of the buttons on the weather station at least 20 times to clear all

memory.

3. Verify that the weather station is blank before proceeding (there may be lines

painted on the screen that will show when there is no power).

4. Leave both units without power for 15 minutes (very important).

5. Insert fresh batteries into the remote sensor.

6. Press the TX button on the remote sensor to transmit RF signal.

7. Keep the remote sensor 5-10 feet from the weather station.

8. When RF connection is established, the temperature will appear on the station.

Allow the remote sensor and weather station to sit together for 15 minutes to

establish a strong connection.

9. Do not press buttons for 15 minutes.

For optimum 433MHz transmission, place the remote sensor no more than 300

feet (91 meters, open air) from the weather station.

See the section on mounting and distance/resistance/interference for details on

mounting the remote sensor.

Remote Temperature Sensor

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 3

Compatible Remote sensors

The TX141TH-BCH remote sensor comes packaged with this weather station.

The TX141TH-ACH (433MHz) remote sensor is compatible with this weather

station.

Quick Connect

Explanation: Use the quick connect for a weather station and remote sensor that

have been working but lost connection due to interference or low batteries. This is

not the same as a thorough factory reset.

1. Bring the remote sensor and weather station together inside, and place the

units 5-10 feet apart with nothing between them.

2. Hold the INFO button for 5 seconds. The remote temperature area will flash.

3. Remove battery cover from the remote sensor and press and release the TX

button to send the signal.

4. Wait for 2 minutes for the remote temperature to appear on the weather

station.

Factory Restart: If the above procedure does not work, please try the factory

reset.

Remote Temperature Signal Strength

Explanation: The weather station will search for the remote temperature/humidity

remote sensor for 3 minutes after batteries are installed or when the INFO button is

held for 3 seconds.

The antenna symbol will flash during reception.

The temperature display will be dashes “---“.

If synchronization fails once, the antenna will lose one bar.

If synchronization fails twice, the antenna will lose two bars.

If RF (radio frequency) reception fails five times, the antenna symbol will show

without bars.

The antenna will show full display with successful RF (radio frequency)

reception.

Dashes show for Remote Temperature

Explanation: Dashes mean the connection is lost between the weather station and

the remote sensor.

Batteries often resolve the connection.

Distance/Resistance can cause loss of connection between the remote sensor

and the weather station.

Turn the weather station 90 degrees towards the remote sensor to provide

better reception. This allows more antenna surface to face the remote sensor

signal.

Try the quick connect or factory restart.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 4

Power Requirements

2-AA batteries power the remote sensor.

We recommend Alkaline batteries for the remote sensor.

You may choose to use Lithium batteries for temperatures below -20°F/-28.8°C.

Inaccurate Remote Temperature Reading

Explanation: High remote temperature readings are generally a location issue.

Low remote temperature readings are power related or a sensors going bad.

The remote sensor reads the environment where it is mounted. When mounted

inside the home, it will read inside temperature/humidity.

When the remote sensor reads high during the day, but not at night, it is a

positioning problem.

Look for heat sources such as sunlight, door or window frames or reflected heat.

Side-by-side test: Place the remote sensor right next to the weather station for 2

hours.

Compare indoor and remote temperature. The temperatures should be within 4

degrees to be within tolerance.

If the remote sensor reads correctly when next to the weather station, try a

different location outside.

Intermittent Remote Temperature

Explanation: Intermittent problems are the hardest to resolve. RF (radio

frequency) communication may come and go occasionally. This can be normal in

some environments (e.g. moister climates). If remote sensor signal is lost, please

wait 2-4 hours for the signal to reconnect on its own.

Move the remote sensor to a closer location.

Distance/Resistance can cause loss of remote sensor signal.

Check Batteries.

Freezer test: Confirm the weather station is reading the correct remote sensor

(not a neighbor’s sensor). Place the remote sensor in the freezer for an hour and

watch the temperature drop on the weather station.

Indoor distance test: Please complete the Restart with remote sensor and

weather station 5-10 feet apart and inside to establish a strong connection.

After 15 minutes, if there is a reading in the remote temperature area, move the

remote sensor to another room with one wall between the remote sensor and

the weather station.

Observe to see if the temperature remains on consistently for 1 hour.

If the temperature remains on while in the house, then it is likely a

distance/resistance issue.

Move the remote sensor to different locations outside to find a location where

the temperature reading will hold.

Remote Temperature is stuck or HH.H, LL.L

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 5

Explanation: These symbols are error messages indicating the remote sensor is

outside of its readable range.

Check Batteries.Overpowered or underpowered batteries can cause this

reading.

Replace remote sensor.

Note: The last remote reading may remain (not change) for several hours when

connection is lost. The remote temperature reading will flash when the connection

is first lost or intermittent.

Remote sensor drains batteries quickly

Test a new set of alkaline batteries. Write down the date of installation and the

voltage of the batteries.

When the batteries fail, please note the date and voltage again.

Check the distance and resistance between the remote sensor and weather

station. Remote sensors at the end of the range may work while batteries are

fresh but not after they drain a bit.

Check for leaking batteries, which may damage the remote sensor.

Battery life is over 24 months when using reputable battery brands for both

Alkaline and Lithium batteries.

Remote sensor fell. The sensor no longer works

Explanation: If there is no physical damage to the remote sensor, the fall may not

have caused internal damage. A fall can shock the remote sensor or the batteries in

the remote sensor. Batteries that have fallen on a hard surface may be damaged

and unable to function properly.

Complete a Restart with fresh batteries.

Use Batteries dated at least six years in advance of the current year. Batteries

dated earlier than six years from now may still work, but may be unstable in

performance.

Note: A remote sensor that has fallen into puddle, snow, or other standing water,

will likely have water damage and need to be replaced. Remote sensors are water

resistant, not waterproof.

Temperature/Humidity Trend Arrows

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 6

Explanation: The indoor and remote temperature (2°F / 1°C) and humidity (3%

RH) trend indicators update every 30 minutes or less. These trends represent

temperature changes over the past three hours.

Example: At 11:00, the trend arrows will reflect changes in temperature or

humidity since 8:00. At 11:30, the trend arrows will reflect changes in temperature

or humidity since 8:30, etc.

Up Arrow:

Temperature has risen in the past 3 hours.

Humidity has risen in the past 3 hours.

Right Arrow:

Temperature has not changed in the past 3 hours.

Humidity has not changed in the past 3 hours.

Down Arrow:

Temperature has fallen in the past 3 hours.

Humidity has fallen in the past 3 hours.

temperatures each day starting at midnight (12:00 AM). The weather station

automatically resets the MIN/MAX temperatures at midnight (12:00 AM).

Press and release the MIN/MAX/- button to view minimum then maximum

temperatures.

Heat Index/Dew Point/Mold Risk

Heat Index:

Heat Index combines the effects of heat and humidity.

Heat Index is what the temperature feels to a human being.

As humidity increases, the body is unable to cool effectively.

The temperature will feel warmer.

View Heat Index: From the default time display, press the INFO button once and

Heat Index will show instead of the remote ambient temperature.

Note: Heat index will be the same number as the temperature until the remote

temperature is above 26.7°C (80°F).

Dew Point Temperature:

Dew Point Temperature is the saturation point of the air, or the temperature to

which the air has to cool in order to create condensation.

The higher the dew points, the higher the moisture content of the air at a given

temperature.

View Dew Point Temperature: From the default time display, press the INFO

button twice and Dew Point will show instead of the remote ambient temperature.

The words “Dew Point” will show near remote temperatures.

Note: Dew Point is lower than the actual temperature.

Mold Risk (Remote and Indoor):

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 7

Mold spores occur in both indoor and outdoor environments.

When mold spores drop on places where there is excessive moisture, mold may

grow.

Place the remote sensor outdoors to monitor backyard weather conditions, or

use it indoors to monitor high mold risk areas like in a crawl space or a

basement.

View Indoor and Remote Mold Risk: From the default time display, press the

INFO button three times to view the mold risk indicators for indoor and remote

station in the home. Wait approximately 1 hour before permanently mounting the

remote sensor to ensure that there is proper reception.

POSITION

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 8

Outdoor:

Protect the remote sensor from standing rain or snow and from the overhead

sun, which can cause it to read incorrectly.

Mounting under an eave or deck rail works well.

If you choose, you can construct a small roof or box for the remote sensor. Be

sure a box has vents.

Mount the remote sensor on the North side where to prevent sun from causing

incorrect readings.

Mount at least 6 feet in the air for a strong RF (radio frequency) signal.

Do not mount the remote sensor on a metal fence. This significantly reduces the

effective range.

Remote sensors are water resistant, not waterproof.

Indoor:

Mount the Remote Sensor indoors to monitor high mold risk areas like in a crawl

space or a basement.

Indoor or Outdoor:

Mount remote temperature sensor vertically.

Avoid more than one wall between the remote sensor and the weather station.

The maximum transmitting range in open air is over 200 feet (60 meters).

Obstacles such as walls, windows, stucco, concrete and large metal objects can

reduce the range.

Do not mount near electrical wires, transmitting antennas or other items that

will interfere with the signal.

RF (radio frequency) signals do not travel well through moisture or dirt.

MOUNT

Option 1:

Install one mounting screw (not included) into a wall.

Place the remote sensor onto the screw (hanging hole on the backside).

Gently pull down to lock the screw in place.

Option 2:

Insert the mounting screw through the front of the remote sensor and into the

wall.

Tighten the screw to snug (do not over tighten).

Position Weather station

The weather station has a pull out stand to sit on a desk or table or can be wall

mounted.

Place within range of the remote sensor.

The maximum transmitting range in open air is 200 feet (60 meters).

Obstacles such as walls, windows, stucco, concrete and large metal objects can

reduce the range.

Choose a location 6 feet or more from electronics such as cordless phones,

wireless gaming systems, televisions, microwaves, routers, baby monitors, etc.,

which can prevent signal reception.

Be aware of electrical wires and plumbing within a wall. This will interfere with

RF (radio frequency) signal reception.

La Crosse Technology, Ltd. www.lacrossetechnology.com/support Page 9

Distance/Resistance/Interference

Distance:

The maximum transmitting range in open air is over 200 feet (60 meters)

between the remote sensor and the weather station. This range is in open air

with ideal conditions.

Consider what is in the signal path between the weather station and the remote

sensor.

Avoid placing electronics in the signal path between the weather station and the

remote sensor.

Resistance:

Obstacles such as walls, floors, windows, stucco, concrete and large metal

objects can reduce the range.

When considering the distance between the remote sensor and the weather

station (200 feet open air), cut that distance in half for each wall, window, tree,

bush or other obstruction in the signal path.

Closer is better.

Windows reflect the RF (radio frequency) signal.

Metal absorbs the signal and reduces the range.

Stucco has a metal mesh that absorbs the signal.

Do not mount the remote sensor on a metal fence. This significantly reduces the

effective range.

Interference:

Consider items in the signal path between the remote sensor and the weather

station.

Sometimes a simple relocation of the remote sensor or the weather station will

correct the interference.

Windows can reflect the radio signal.

Metal will absorb the RF (radio frequency) signal.

Stucco has a metal mesh that absorbs signal.

Avoid transmitting antennas: (ham radios, emergency dispatch centers, airports,

military bases, etc.)

Electrical wires (utilities, cable, etc.)

Vegetation is full of moisture and reduces signal.

It is difficult for RF (radio frequency) signal to travel through a hill.
