Outdoor Temperature Sensor
Compatible Outdoor sensors
The TW004 (433MHz) outdoor sensor comes packaged with this weather station.
This is the only compatible sensor.
Outdoor Temperature Signal Strength
Explanation: The weather station will search for the outdoor temperature outdoor
sensor for 3 minutes once batteries are installed or when the

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

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.
Power Requirements
2-AAA
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.
Inaccurate Outdoor Temperature Reading
Explanation: High outdoor temperature readings are generally a location issue.
Low outdoor temperature readings are power related or a sensor going bad.
The outdoor sensor reads the environment where it is mounted. When mounted
inside the home, it will read inside temperature.
When the outdoor 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.
