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.
Note:
Heat index will be the same number as the temperature until the temperature is above 80 degrees
°F (26.7°C).
View Heat Index:
From a normal display press the HEAT/DEW button once and the Heat Index will show
(indoor/outdoor) instead of the ambient temperature. The words Heat Index will show near the indoor and
outdoor temperatures.
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.
Note:
Dew Point is lower than the actual temperature.
View Dew Point:
From a normal display press the HEAT/DEW button twice and the Dew Point
temperature will show (indoor/outdoor) instead of the ambient temperature. The words Dew Point will
show near the indoor and outdoor temperatures.
Outdoor Temperature/Humidity Flashing
Low battery icon present: Change batteries in the transmitter, and then hold the CH button until the
station beeps to search for the outdoor transmitter again.
End of Transmission Range: Move the transmitter closer to the Wireless Forecast Station. Avoid
obstructions in the signal path. Keep transmitter and Wireless Forecast Station away from electronics.
Low Battery Icon
When this icon appears in the indoor (IN) data reading section, replace the batteries in the Wireless
Forecast Station.
When this icon appears in the outdoor (OUT) data readings section, replace the batteries in the
outdoor transmitter.
