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
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.
