Dashes, HH.H, LL.L, or stuck Indoor Temperature/Humidity 

 

Explanation: 

These symbols are error messages indicating the indoor sensor is outside of its 

readable range. For indoor readings, this is generally a power-related issue.  
 

 

Check that the AC power cord is inserted into a working outlet. 

 

Batteries 

may be overpowered or underpowered. Remove batteries from the weather station.  

 

Press any button 20 times. Leave the weather station unpowered for 1-2 hours.  

 

Install fresh Alkaline batteries with the correct polarity.  

 

If the indoor temperature still shows dashes, HH.H or LL.L, the weather station may need 
replacement. 
 

Inaccurate Indoor Temperature Reading 

 

Explanation: 

When the indoor temperature is inaccurate, it is often due to the location of the 

display or overpowered/underpowered batteries. You can test the accuracy at your home.

 

 
Side-by-side test:

 Bring the outdoor sensor to the house and place it next to the weather station 

for 2 hours.  

 

Compare indoor and outdoor temperatures. The temperature should be within 4 degrees to be 
within tolerance.  

 

Look for heat sources such as sunlight, door, or window frames, or reflected heat or cold near 
the weather station.
