WHY WEATHER FORECAST AND TREND
MAY APPEAR TO CONFLICT
The weather forecast symbols and the pressure trend
signs may show information that at first sight may appear
contradictory.
The pressure trend will only show the most recent
pressure trend, since the measurements are recorded
on an hourly basis. The weather forecast symbols
however indicate a longer term development of the
weather which is forecast to occur over the next 12-24
hours.
It often happens that the pressure will rise or fall
temporarily. With such temporary pressure changes the
trend sign will show "Up" or "Down" respectively but the
longer term weather forecast symbols will not change if
the short term temporary pressure change has been too
small to influence the weather.
We recommend that our users should review the
Barometer frequently, because the short-term pressure
changes shown by the trend sign may give an early
indication of a change to the weather forecast over the
next few hours.

HOW TO READ THE RELATIVE HUMIDITY
AND COMFORT INDICATOR
The unit shows the indoor relative humidity automatically
and such reading is temperature compensated. At the
same time, the comfort indicators COMFORT, WET, or
DRY will tell you if the current environment is comfortable,
too wet or too dry.
The comfort indicators will appear on the display when
the following conditions are satisfied:
