The outdoor sensor reads the environment where it is mounted. When mounted inside 
the home, it will read inside temperature/humidity. 

 

When the outdoor 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 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.  

 

Check 

Batteries

. 

 

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 the 

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 

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. 
 

 

Check 

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.  

 

Check the 

distance

 and 

resistance

 between the outdoor sensor and weather station. 

Outdoor sensors at the end of the range may work while batteries are fresh but not after 
they drain a bit.
