3) Place the indoor temperature station onto the screw 

using the hanging hole on the backside.  Gently pull 
the station down to lock the screw into place. 

 

TROUBLESHOOTING 
 
Problem:

 The LCD is faint 

Solution:

 Replace batteries 

 

Problem: 

No outdoor temperature is displayed. 

Solution:

  

1. Remove all batteries, reinsert into remote temperature sensor first, then 

into the indoor temperature station. 

2. Place remote temperature sensor closer to the indoor temperature 

station. 

3. Be sure all batteries are fresh. 
4. Place remote temperature sensor and indoor temperature station in 

position so the straight-line signal is not passing through more than two 
or three walls. 

Problem:

 Temperatures do not match if units are placed next to each other. 

Solution:

  

Each temperature sensor is manufactured to be accurate to within 1 
degree plus or minus and under normal conditions, so two sensors could 
be as much as 2 degrees different. However, the difference can be 
exaggerated further because the sensors are designed for different 
working environments. The indoor sensor is less responsive to ambient 
air currents because of the shielding effect of the display's case. In 
addition, the case can act as a heat sink to absorb and store heat from 
external sources (i.e. handling of the case or radiant heat). Also, the much 
greater range of the outdoor temperature sensor requires a different 
calibration curve than the indoor range. Error is usually greater at the 
extreme ends of a range, making it harder to compare different ranges 
with different curves. Under non-laboratory conditions, it is difficult to 
compensate for the above factors and obtain an accurate comparison.
