Wind Chill
When reading the Weather Index display, you can press the INDEX button to cycle through different
weather indexes in the following order:
Feels Like > Heat Index > Wind Chill > Dewpoint.
The Feels Like temperature index determines what temperature it actually feels like outside, taking
into account factors like wind chill and the heat index.
Wind chill is determined by a combination of the wireless weather sensor’s temperature and wind
speed data.
the signal icon will disappear. The temperature and humidity will display “--” for the
corresponding channel.
4. If the signal does not recover within 48 hours, the “--” display will become permanent you
need to replace the batteries of “--” channel’s sensor(s) and then press
[ SENSOR / SYNC]
key to pair up the sensors of each “--” channels again.
NOTE:
After replacing the batteries of the wireless sensor or the unit fails to receive sensor signal of

COMFORT INDICATION
The comfort indication is a pictorial indication based on indoor air temperature and humidity in
an attempt to determine comfort level.

NOTE:
Comfort indication can vary under the same temperature, depending on the humidity.
There is no comfort indication when temperature is below 0°C (32°F) or over 60°C (140°F).

Heat Index
Dew Point
The heat index is determined by the wireless weather sensor’s temperature and humidity readings
when the temperature outdoors is between 80°F (27°C) and 120°F (50°C).
• The dew point is the temperature below which the water vapor in air at constant barometric
pressure condenses into liquid water at the same rate at which it evaporates. The condensed water
is called dew when it forms on a solid surface.
• The dew point temperature is determined by the temperature and humidity data from the wireless
weather sensor.
