sensor.
Outdoor Temperature Sensor
Compatible Outdoor sensors
 The TX141TH-
Bv3
outdoor sensor comes packaged with this weather station.
 The TX141TH-A, TX141TH-B (all versions) are compatible.
Quick Connect
Explanation:
Use the quick connect for a weather station and outdoor 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 outdoor sensor and weather station together inside, and place the units 5-10 feet apart with
nothing between them.
2. Hold the
TEMP
button for 5 seconds. The outdoor temperature area will flash.
3. Remove battery cover from the outdoor sensor and press and release the TX button to send the signal.
4. Wait for 2 minutes for the outdoor temperature to appear on the weather station.
 Factory Restart: If the above procedure does not work, please try the factory reset.
Outdoor Temperature Signal Strength
Explanation:
The weather station will search for the outdoor temperature/humidity sensor for 3 minutes
after installing batteries or after holding the
TEMP
button for 3 seconds.
 Hold the
TEMP
button for 3 seconds to search for the outdoor temperature/humidity sensor.
 The strength signal icon will animate until the sensor signal is received, or for 3 minutes if no signal
available.
Dashes show for Outdoor Temperature
Explanation:
Dashes mean the connection is lost between the weather station and the outdoor sensor.
 Batteries often resolve the connection.
 Distance/Resistance can cause loss of connection between the outdoor sensor and the weather station.
 Turn the weather station 90 degrees towards the outdoor sensor to provide better reception. This
allows more antenna surface to face the outdoor sensor signal.
 Try the quick connect or factory restart.
Power Requirements
 2-AA batteries power the outdoor sensor.
 We recommend Alkaline batteries for the outdoor sensor.
 You may choose to use Lithium batteries for temperatures below -20°F/-28.8°C.
