HEAT INDEX & DEW POINT EXPLAINED

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. The temperature will feel warmer.

Dew Point:
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.

TEMPERATURE & HUMIDITY TREND ARROWS

The temperature and humidity trend indicators update with every 15 minutes and look back over the past hour.

Change in temperature (2°F / 1°C, 3% RH).
1 hrs comparison which changes on every 1/4 hour

E.g.: At 1:00 – compare to 12:00 data; at 1:15 -compare to 12:15: at 1:30 – compare to 12:30 ….. etc

SENSOR SEARCH

If you are seeing dashes in place of outdoor temperature, first check your sensor batteries.
Hold the TEMP button for 3 seconds to search for the sensor. Sensor Reception icon will flash while searching and be solid when sensor signal is received.
If you regain connection while the sensor is mounted, great. If you do not regain connection, bring the sensor within 10 feet of the station and search again.

Note:

If the signal is lost, the RX will display the ast data recorded from sensor for 10 minutes.
After that 10 minutes if the signal does not come back then you will see dashes “–”.
After 30 minutes, start looking for the sensor signal automatically.

FORECAST ICONS
