
The TX141TH-A, TX141TH-Av2 and TX141TH-B (433MHz) remote sensors are
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 HEAT/DEW 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 sensor
for 3 minutes after installing batteries or after holding the HEAT/DEW button 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.
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.
