Humidity Trend Arrows; Hi/Lo Temperature Readings; Heat Index/Dew Point - La Crosse Technology C87214 Faq

Arrows trending left: Temperature is falling.
Arrows trending right: Temperature is rising.

Humidity Trend Arrows

Explanation: The indoor and outdoor humidity (3% RH) trend indicators update every 30
minutes or less. These trends represent temperature changes over the past three hours.
Example: At 11:00, the trend arrows will reflect changes in humidity since 8:00. At 11:30,
the trend arrows will reflect changes in humidity since 8:30, etc.
Up Arrow:
 Temperature has risen in the past 3 hours.
 Humidity has risen in the past 3 hours.
Right Arrow:
 Temperature has not changed in the past 3 hours.
 Humidity has not changed in the past 3 hours.
Down Arrow:
 Temperature has fallen in the past 3 hours.
 Humidity has fallen in the past 3 hours.

HI/LO Temperature readings

Explanation: The weather station shows the daily LO and HI temperatures each day
starting at midnight (12:00 AM). The weather station automatically resets the HI/LO
temperatures at midnight (12:00 AM).
 View HI data: Press the ▲ button once to view HI temperature and humidity values for
indoor and outdoor data.
 Reset HI data: Hold the ▲ button for five seconds to reset HI temperature and
humidity values for indoor and outdoor data.
 View LO data: Press the ▼ button once to view LO temperature and humidity values
for indoor or outdoor data.
 Reset LO data: Hold the ▼ button for five seconds to reset LO temperature and
humidity values for indoor and outdoor data.

Heat Index/Dew Point

Heat Index:
 Heat Index combines the effects of heat and humidity.
 Heat Index is what the temperature feels to a human being.
 As humidity increases, the body is unable to cool effectively.
 The temperature will feel warmer.
View Heat Index: From the default time 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 26.7°C (80°F).
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 the default time 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.
