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 (on the left
side of the LCD) 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. INDOOR TEMPERATURE, HUMIDITY, AND COMFORT LEVEL INDICATOR
The current indoor temperature and relative humidity are displayed in the INDOOR LCD.
The comfort level indicator is located at the center of the INDOOR LCD. The indicator will display a happy face icon
when the temperature is between 68
°F and 78.6°F, and the humidity is between 45% and 65%. A sad face icon will be
displayed when the temperature and humidity are outside the mentioned ranges.
III. OUTDOOR TEMPERATURE AND HUMIDITY / HEAT INDEX / DEWPOINT
The temperature and humidity received from the remote temperature/humidity sensor is viewed in the OUTDOOR LCD.
When there is more than one remote temperature/humidity sensor unit in operation, a “boxed” number will appear to the
center 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). The Heat Index and Dew Point will then be calculated from the received temperature/humidity readings.
IV. MINIMUM AND MAXIMUM TEMPERATURE, HEAT INDEX AND DEW POINT RECORDS
The WS-9118U keeps a record of the MINIMUM and MAXIMUM and date of their occurrence, for both the indoor and
outdoor modes.
A. VIEWING THE INDOOR TEMPERATURE AND HUMIDITY RECORDS
1. Press and release the IN/HR button once. “MAX” temperature appears with the indoor temperature,
indicating that the maximum temperature and the time and date of occurrence are displayed. The maximum
record will display for 30 seconds before returning to the normal display mode.
2. Press and release the IN/HR button again (once while “MAX” temperature is still displayed, twice
otherwise). “MIN” appears with the indoor temperature, indicating that the minimum temperature and the
time and date of occurrence are displayed. The minimum record will display for 30 seconds before
returning to the normal display mode
3. Press and release the IN/HR button again (once while “MIN” temperature is still displayed, 3 times
otherwise). “MAX” appears with the indoor humidity, indicating that the maximum humidity and the time
and date of occurrence are displayed. The maximum record will display for 30 seconds before returning to
the normal display mode.
4. Press and release the IN/HR button again (once while “MAX” humidity is still displayed, 4 times
otherwise). “MIN” appears with the indoor humidity, indicating that the minimum temperature and the
time and date of occurrence are displayed. The minimum record will display for 30 seconds before
returning to the normal display mode
