•
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 atomic clock 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 atomic clock, 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.
•
Freezer test: Confirm the atomic clock 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 atomic clock.
Indoor distance test: Please complete the
with Outdoor Sensor and Atomic Clock 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 atomic clock.
•
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 shows HH.H, LL.L
Explanation: These symbols are error messages indicating the Outdoor sensor is outside of its readable
range.
•
Overpowered or underpowered batteries can cause this reading.
•
Replace Outdoor sensor.
Outdoor 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 outdoor sensor and atomic clock. Outdoor 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 outdoor sensor.
•
Battery life is over 24 months when using reputable battery brands for both Alkaline and Lithium
batteries.
