Heat Index 

 
Heat Index combines the effects of heat and humidity. It is the apparent temperature of how hot it feels to 
a human being. When relative humidity increases, the air feels warmer than it actually is because your 
body is less able to cool effectively by evaporation of perspiration. 
 

 

View Heat Index:

 From a normal display press the HEAT/DEW button once and the Heat Index will show 

instead of the ambient temperature. The words Heat Index will show near the indoor and outdoor 
temperatures. 
 

Note:

 Heat index will be the same number as the temperature until the temperature is above 80 degrees 

°F (26.7°C). 
    

Dew Point Temperature 

 
Dew point is the saturation point of the air, or the temperature to which the air has to be cooled in order to 
create condensation. The higher the dew points, the higher the moisture content of the air at a given 
temperature. Dew Point Temperature is the absolute measure of the moisture in the air at a given 
temperature. Relative humidity is the relative measure of moisture in the air at a certain temperature. 

 

 

 
View Dew Point:

 From a normal display press the HEAT/DEW button twice and the Dew Point 

temperature will show instead of the ambient temperature. The words Dew Point will show near the 
indoor and outdoor temperatures. 
 

Note:

 Dew Point is lower than the actual temperature. 

    

Low Battery Icon

 

 

 

When this icon   appears in the indoor (IN) data reading section, replace the batteries in the forecast 
station.  

 

When this icon   appears in the outdoor (OUT) data readings section, replace the batteries in the 
outdoor transmitter.  

 

Use Multiple Outdoor Transmitters 

 
The forecast station will accommodate up to three remote outdoor transmitters (TX142TH or TX14TH). 
The channel selection button allows you to easily see the temperature in various locations: outdoors, 
baby’s room, greenhouse, basement, etc. 
 

To connect multiple remote transmitters to the forecast station: 

1.  Remove the battery cover from all the transmitters (Leave battery covers off 

until all transmitters are received by the forecast station). 

2.  Set the 

first

 outdoor transmitter to 

Channel 1

 and insert 2-AA batteries.  

3.  Set the 

second

 outdoor transmitter to 

Channel 2

 and insert 2-AA batteries. 

4.  Set the 

third

 outdoor transmitter to 

Channel 3

 and insert 2-AA batteries. 

5.  Press and hold CH button on the forecast station until a beep sounds. The 

forecast station will search for all outdoor transmitters.
