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.

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 th

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. 

 

 

Chec

Batteries.

 Overpowered or underpowered batteries can cause this 

reading. 

 

Replace outdoor sensor. 

Note: The last outdoor reading may remain (not change) for several hours when 

connection is lost. The outdoor temperature reading will flash when the connection 

is first lost or intermittent.  

 

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.
