You may choose to use Lithium batteries for temperatures below -20°F/-28.8°C. 

 

 

Inaccurate Remote Temperature Reading 

 

Explanation: High remote temperature readings are generally a location issue. 

Low remote temperature readings are power related or a sensors going bad. 

 

 

The remote sensor reads the environment where it is mounted. When mounted 

inside the home, it will read inside temperature. 

 

When the remote 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 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. 

 

Distance/Resistance 

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 th

Restart 

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 

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.
