Heat Index/Dew Point
The
HEAT/DEW
button toggles between Heat Index, 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. When relative humidity increases, the air feels
warmer than it actually is because your body is less able to cool effectively by
evaporation of perspiration.
Note:
Heat index will be the same number as the temperature until the temperature is
above 80 degrees °F (26.7°C).
View Heat Index:
From a normal display press the HEAT/DEW button once and the
Heat Index will show (indoor/outdoor) instead of the ambient temperature. The words
Heat Index will show near the indoor and outdoor temperatures.
Dew Point Temperature
Dew point is the saturation point of the air, or the temperature to which the air has to be
cooled in order to create condensation. The higher the dew points, the higher the
moisture content of the air at a given temperature. Dew Point Temperature is the
absolute measure of the moisture in the air at a given temperature. Relative humidity is
the relative measure of moisture in the air at a certain temperature.
Note:
Dew Point is lower than the actual temperature.
View Dew Point:
From a normal display press the HEAT/DEW button twice and the Dew
Point temperature will show (indoor/outdoor) instead of the ambient temperature. The
words Dew Point will show near the indoor and outdoor temperatures.
Outdoor Temperature/Humidity flashing
Low battery icon present
: Change batteries in the sensor, and then hold
the
CH
button until the station beeps to search for the outdoor sensor again.
End of Transmission Range
: Move the sensor closer to the forecast station. Avoid
obstructions in the signal path. Keep sensor and forecast station away from
electronics.
Use Multiple Outdoor Sensors
The forecast station will accommodate up to three outdoor sensors (TX142THv2). The
channel selection (CH) button allows you to easily see the temperature in various
locations: outdoors, baby’s room, greenhouse, basement, etc.
To connect multiple outdoor sensors to the forecast station:
1.
Remove the battery cover from all the sensors (Leave battery covers off until all
sensors are received by the forecast station).
2.
Set the first outdoor sensor to Channel 1 and insert 2-AA batteries.
