Heat Index/Dew Point
The HEAT/DEW button toggles between Heat Index, Dew Point, and Mold Risk.
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.
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 arrow will indicate the temperature change since 10:30am.
Temperature has risen in the past 3 hours.
Humidity has risen in the past 3 hours.
Temperature has not changed in the past 3 hours.
Humidity has not changed in the past 3 hours.
Temperature has fallen in the past 3 hours.
Humidity has fallen in the past 3 hours.

Hold the HEAT/DEW button to search for the remote sensor.
The strength signal icon will animate until the sensor signal is received or for
3 minutes if no signal available.
MIN/MAX (View, Reset)
The Weather station provides the daily minimum and maximum temperatures each day
starting at midnight (12:00 AM). The Weather station automatically resets the min/max
temperatures at midnight (12:00 AM).
View MIN data: Press and release the ▼ button to view the minimum
Indoor and Remote Temperatures.
Reset MIN data: Hold the ▼ button for five seconds and the Indoor and
Remote Minimum Temperatures will be reset.

Remote Temperatures.
Reset MAX data: Hold the ▲ button for five seconds and the Indoor and all Remote
Maximum Temperatures will be reset.
Note: The temperature area shows dashes briefly then return to current temperatures.
Animated Color Forecast Icons
Animated forecast icons use changing atmospheric pressure to predict weather
conditions for the next 12-hours with 70-75% accuracy.
INTELLIGENT WEATHER FORECAST
This station learns; please allow 3 to 4 weeks for barometric calibration. This will ensure
an accurate personal forecast for your location.
The Weather station samples the barometric pressure every twelve minutes.
These samples are averaged hourly and daily then stored in nonvolatile memory.
The three hour pressure icon change is based off of the last four average hourly
readings.
Model: S88907
Page | 11
IMPORTANT: As the Weather station builds memory, it will compare the current
average pressure to the past forty day average pressure for increased accuracy. The
longer the Weather station operates in one location, the more accurate the forecast icons
will be.
Pressure Tendency Indicators (Up, Right, Down Arrows)
Working with the forecast icons, the tendency indicators let you know if the weather is
improving, steady or worsening.
