Heat Index/Dew Point
The HEAT/DEW button toggles between Heat Index, and Dew Point. Each feature will display for
10 seconds then return to default display if the button is not pressed again.
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 in place of the remote temperature.
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.

Model: 308-1425CA https://www.lacrossetechnology.com/308-1425ca Page | 10
View Dew Point Temperature:
From a normal display, press the HEAT/DEW button twice and Dew Point will show place of the
remote temperature.
Note: Dew Point is lower than the actual temperature.
Temperature/Humidity Trend indicators
The indoor and remote temperature/humidity trend indicators will update every 30 minutes or less.
These trends represent temperature changes over the past three hours.
Example: At 1:00pm, the arrow indicates the change in temperature since 10:00am. At 1:30pm, the
