Each remote sensor will have its own minimum and maximum values
stored.
C. Comfort Indicator for Indoor Temperature and Humidity
1. The comfort level indicator appears inbetween the indoor
tempearture and humidity.
2. The indicator will display a “happy-face” when the temperature is
between 68
°F and 79°F (20°C and 25.9°C), and the humidity is
between 45% and 64%.
3. A “sad-face” will be displayed when the temperature and humidity
are outside the mentioned ranges.
D. Weather Forecast Icon and Pressure Trend Indicators
The weather forecasting feature is estimated to be 75% accurate, and is
based solely upon the change of air pressure over time. The WS-
7394U averages past air-pressure readings to provide an accurate
forecast—creating a necessity to disregard all weather forecasting for
12-24 hours after the unit has been set-up, reset, or moved from one
altitude to another (i.e. from one floor of a building to another floor).
In areas where the weather is not affected by the change of air pressure,
this feature will be less accurate.
1. Weather Icons
a. There are 3 possible weather icons that will be displayed at
various times in the center of the indoor weather station.
i Sunny—indicates that the weather is expected to improve
(not that the weather will be sunny).
ii Sun with Clouds—indicates that the weather is expected to
be fair (not that the weather will be sunny with clouds).
iii Clouds with Rain—indicates that the weather is expected
to get worse (not that the weather will be rainy).
b. The weather icons change when the unit detects a change in
air pressure.
c. The icons change in order, from “sunny” to “sun with clouds”
to “clouds with rain” or the reverse.
d. It will not change from “sunny” directly to “clouds with rain”,
although it is possible for the change to occur quickly.
