
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.
Inaccurate Outdoor Temperature Reading
Explanation: High outdoor temperature readings are generally a location issue. Low
outdoor temperature readings are power related or a sensors going bad.

The outdoor sensor reads the environment where it is mounted. When mounted inside
the home, it will read inside temperature/humidity.

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.
Side-by-side test: Place the outdoor sensor right next to the weather station for 2 hours.

Compare indoor and outdoor temperature. The temperatures should be within 4 degrees
to be within tolerance.

If the outdoor sensor reads correctly when next to the weather station, try a different
location outside.
Intermittent Outdoor 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 outdoor sensor signal is lost, please wait 2-4 hours for the signal
to reconnect on its own.

Move the outdoor sensor to a closer location.

Distance/Resistance can cause loss of outdoor sensor signal.

Check Batteries .
Freezer test: Confirm the weather station is reading the correct outdoor sensor (not a
neighbor’s sensor). Place the outdoor sensor in the freezer for an hour and watch the
temperature drop on the weather station.
Indoor distance test: Please complete the Restart with outdoor 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 outdoor temperature area, move the
outdoor sensor to another room with one wall between the outdoor 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 outdoor sensor to different locations outside to find a location where the
temperature reading will hold.
Outdoor Temperature is stuck or HH.H, LL.L
Explanation: These symbols are error messages indicating the outdoor sensor is outside of
its readable range.

Check Batteries. Overpowered or underpowered batteries can cause this reading.

Replace outdoor sensor.
