COMFORT LEVEL INDICATOR
The comfort level indicator appears in the center portion of LCD 2
(between the Indoor temperature and the Indoor humidity) as either a
“happy-face” or as a “sad-face”. 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%. A “sad-face” will
be displayed when the temperature and humidity are outside the
mentioned ranges.
If the humidity is below 45% the word “DRY” will appear to the right
of the “happy-face” icon. If the humidity is above 54% the word “wet”
will appear to the right of the “sad-face” icon.

BAR GRAPH HISTORIES
A.
AIR PRESSURE HISTORY
The air pressure is indicated by the appearance of the word
“PRESSURE” at the top of the LCD 4 screen.
The bar graph (in LCD 4) shows in hPa (Hekto Pascal) the recorded air
pressure over the past 48-hours. The horizontal axis shows the hours at
increments of 48-hours, 36-hours, 24-hours, 18-hours, 12-hours,
6-hours, 3-hours, 1-hour, and 0-hours. The vertical axis is set by hPa:
the “0” on this axis represents the current hPa, and + or – 1,3,5, or 7
shows (in hPa) how high or low the past air pressure was as compared
to the current one. The “0” on the vertical axis indicates the air
pressure value seen in LCD 5. The “0” on the horizontal axis indicates
that the “0” on the vertical axis is the present air pressure. Each brick
on the bar graph represents a value of 0.03 hPa, and each brick also has
a corresponding value on the verticle axis. Multiply the two values to
find past air pressure (note the + or – sign of values on the verticle
axis); i.e. 0.03 hPa x 3 = 0.09 hPa, now add this value to the air
Position “0” on both the vertical and horizontal axis indicates present air
pressure. “-1” on the horizontal was 1-hour ago. The top bar corresponds
with “+1” on the vertical axis, multiply 0.03 x (+1) and we get +0.03 hPa.
Add +0.03 to current air pressure readings to attain the air pressure 1-hour
ago. A decline in air pressure is shown between the “-24” and “-3” hours.
