Indoor relative humidity with comfort level reading (face icons) and Outdoor
relative humidity reading
The indoor relative humidity with comfort level reading and the outdoor relative humidity reading are
displayed respectively underneath the indoor and outdoor temperatures. With the comfort level
feature, users can determine how comfortable the indoor relative humidity is within their current
surroundings. Again, as with the indoor temperature, the indoor relative humidity reading will
automatically be taken once the batteries are inserted into the Weather station. The indoor relative
humidity is updated every minute.
Once the batteries are inserted into the Thermo-Hygro transmitter, the Weather Station will also start
receiving data from the transmitter. The outdoor relative humidity will then be displayed and will be
updated every 5 minutes.
Working together with relative humidity, the Weather Station will register a comfort level reading by
representation of a "
☺
" Happy" or "
L
" Sad face. The temperature range b20ºC to +25.9ºC
(+68ºC to +79ºC) and relative humidity range between
45
% to
66
% will register the "Happy" face. The
"Sad" face will appear should either the temperature or humidity readings be outside these set
ranges. This means, the "Happy" face represents a comfortable level and the "Sad" face represents
an uncomfortable one.
When the "
L
" "Sad" face appears with the word "DRY" or "WET", it means that the relative humidity
reading is outside its comfort level range. However, "DRY" or "WET" will not appear if only the
temperature reading is outside its comfort level range. The "
L
" "Sad" face and "Dry" will appear if the
relative humidity level is below
44
% or "WET" will appear if the level is above
67
%.
Weather tendency icons
There are 3 weather icons on the LCD which can be displayed in any one of the following
combinations:
Sunny
Cloudy with sunny intervals
Rainy
For every sudden or significant change in the air pressure, the weather icons will update accordingly
to represent the change in weather. If the icons do not change, then it means either the air pressure
has not changed or the change has been too slow for the Weather Station to register. However, if the
icons displayed is a sun or raining cloud, there will be no change of icon if the weather gets any better
(with sunny icon) or worse (with rainy icon) since the icons are already at their extremes.
The icons displayed forecasts the weather in to terms of getting better or worse and not necessarily
sunny or rainy as each icon indicates. For example, if the current weather is cloudy and the rainy icon
is displayed, it does not mean that the product is faulty because it is not raining, it simply means that
the air pressure has dropped and the weather is expected to get worse but not necessarily rain.
Note:
After setting up, readings for weather forecasts should be discarded for the next 12-24 hours. This will
allow sufficient time for the Weather Station to operate at a constant altitude and therefore result in a
more accurate forecast.
Common to weather forecasting, absolute accuracy cannot be guaranteed. The weather forecasting
feature is estimated to have an accuracy level of about 75% due to the varying areas the Weather
Station has been designed for use in. In areas that experience sudden changes in weather (for
example from sunny to rain), the Weather Station will be more accurate compared to use in areas
where the weather is stagnant most of the time (for example mostly sunny).
If the Weather Station is moved to another location significantly higher or lower than its initial standing
point (for example from the ground floor or the first floor of a house), remove the batteries and re-
insert them after about 30 seconds. By doing this, the Weather Station will not mistake the new
location as being a possible change in air-pressure when really it is due to the slight change of
altitude. Again, discard weather forecasts for the next 12 to 24 hours as this will allow time for
operation at a constant altitude.
The weather tendency indictor
The weather tendency arrows are located above and below the weather icons and indicate the
change in air-pressure and thus, forecasts the expected weather.
The tendency arrows can be displayed as follows:-
•
Tendency arrow pointing upwards
:
This means that the air-pressure is increasing and so the weather is expected to improve.
•
Tendency arrow pointing downwards
:
This means that the air-pressure is decreasing and the weather is expected to become worse.
Taking this into account, the unit can also show how the weather has changed and is expected to
change. For example if the arrow pointing downwards is displayed together with cloud and sun
weather icons, then the last noticeable change in the weather was when it was sunny (the sun icon
only was shown). This means that the next change in the weather will be rainy icons since the
tendency arrow is pointing downwards.
Note:
The weather tendency indictor arrows remain on the LCD regardless of the current weather. For
example, if the current weather is raining, and the arrow is pointing downwards, it means that the
weather will remain poor and if the weather is sunny and the arrow is pointing upwards, it means that
the weather is expected to remain fine.
Outdoor Temperature Reading:
The outdoor temperature is displayed underneath the weather icons section. The Weather Station
will automatically start scanning transmitter's 433 MHz signal after the batteries are inserted and once
received, the outdoor temperature will appear on the LCD.
Minimum and maximum outdoor temperature recordings:
On the bottom line of the LCD are the outdoor minimum and maximum temperature recordings.
These are simultaneously displayed for a constant update and easy reading. When a new
temperature low or high is reached, it will be updated and recorded into the Weather Station’s
memory.
Resetting minimum and maximum indoor and outdoor temperatures
The minimum and maximum indoor and outdoor temperature can be reset by pressing the RESET
key for 3 seconds. Once the RESET key is pressed, all indoor and the selected outdoor data will
update to the current.
Note:
When resetting the minimum and maximum outdoor temperatures, the data from the selected
transmitter will only be reset. The minimum and maximum outdoor temperatures from the other
outdoor transmitters will not be reset. Each outdoor data have to be reset separately.
Thermo-Hygro transmitter:
The temperature and humidity are measured every 1 minute and transmitted every 5 minutes.
