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.
