I. WEATHER 

FORECAST 

The weather forecasting feature is estimated to be 75% accurate and is for the next 12 to 24 hours. The 

weather forecast is based solely upon the change of air pressure over time. The WS-9075U 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 largely affected by 
the change of air pressure, the sensitivity setting should be set to 1. In areas where the air pressure 
changes more rapidly (such as coastal areas) the sensitivity setting should be set to 3. 

 

A. WEATHER ICONS 

There are 3 possible weather icons that will be displayed in the FORECAST LCD:   

 

 
 
 
 

Sunny

—indicates that the weather is expected to improve (not that the weather will be sunny). 

 

Sun with Clouds

—indicates that the weather is expected to be fair (not that the weather will be 

sunny with clouds). 

 
Clouds with Rain

—indicates that the weather is expected to get worse (not that the weather will 

be rainy). 
 
These icons indicate the expected weather change in the next 12 to 24 hours. The icon does not 
give an exact prediction of the weather, however it should be viewed as a generalization of the 
expected weather change (for example a “sunny” icon indicates the weather is expected to 
improve). 
 
The weather icons change when the unit detects a change in air pressure. The icons change in 
order, from “sunny” to “partly sunny” to “cloudy” or the reverse. It will not change from 
“sunny” directly to “rainy”, although it is possible for the change to occur quickly. If the symbols 
do not change then the weather has not changed, or the change has been slow and gradual.  
 

B.  WEATHER TENDENCY ARROWS 

Other possible displays in the FORECAST LCD are 2 weather tendency arrows, one that points 
up and one that points down (on the right side of the LCD). These arrows reflect current changes 
in the air pressure. An arrow pointing up indicates that the air pressure is increasing and the 
weather is expected to improve or remain good, an arrow pointing down indicates that the air 
pressure is decreasing and the weather is expected to become worse or remain poor. 
 

II.  OUTDOOR TEMPERATURE  

The temperature received from the remote temperature sensor is viewed in the OUTDOOR LCD. When 
there is more than one remote temperature sensor unit in operation, a “boxed” number will appear to the 
left side of the temperature. This indicates which remote temperature sensor unit (1, 2, or 3) is currently 
displaying its data in the OUTDOOR LCD. (This feature is explained in further detail in section 

VII

Adding Remote Temperature Sensors

). 

 

III.  INDOOR TEMPERATURE, HUMIDITY, AND COMFORT LEVEL INDICATOR 

The current indoor temperature and relative humidity are displayed in the INDOOR LCD.
