Look for heat sources such as sunlight, door or window frames or reflected heat.
Side-by-side test: Place the remote sensor right next to the atomic clock 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 atomic clock, 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.
can cause loss of remote sensor signal.
Freezer test: Confirm the atomic clock 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 atomic clock.
Indoor distance test: Please complete the
with remote 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 remote temperature area, move the remote sensor to
another room with one wall between the remote 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
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.
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
resistance
between the remote sensor and atomic clock. 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.
