Heat Index and Dew Point Temperature
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. As humidity increases, the body is unable to cool effectively; therefore, the temperature
will feel warmer.
View Heat Index:
From a normal display, press the HEAT/DEW button once and Heat Index will show
instead of the outdoor ambient temperature.
Note:
Heat index will be the same number as the temperature until the outdoor temperature is above 80
°F (26.7°C).
Dew Point Temperature
Dew Point Temperature is the saturation point of the air, or the temperature to which the air has to cool in
order to create condensation. The higher the dew points, the higher the moisture content of the air at a
given temperature.
View Dew Point Temperature:
From a normal display, press the HEAT/DEW button twice and Dew
Point will show instead of the outdoor ambient temperature. The words Dew Point will show near outdoor
temperatures.
Note:
Dew Point is lower than the actual temperature.
