WEATHER TENDENCY INDICATOR
Working together with the weather icons is the weather tendency indicators (located on the left and
right sides of the weather icons). When the indicator points upwards, it means that the air-pressure
is increasing and the weather is expected to improve, but when indicator points downwards, the air-
pressure is dropping and the weather is expected to become worse.
Taking this into account, one can see how the weather has changed and is expected to change. For
example, if the indicator is pointing downwards together with cloud and sun icons, then the last
noticeable change in the weather was when it was sunny (the sun icon only). Therefore, the next
change in the weather will be cloud with rain icons since the indicator is pointing downwards.
Note:
Once the weather tendency indicator has registered a change in air pressure, it will remain
permanently visualized on the LCD.
AIR PRESSURE HISTORY (ELECTRONIC BAROMETER WITH BAROMETRIC
PRESSURE TREND)
The third section of the LCD
also
shows the
relative
air pressure
value
and the air pressure
history
.
The bar chart indicates the air pressure
history
trend over the last
24 hours
in 7 steps, 0h, -3h, -6h,
-9h, -12h, -18h, and -24h. The “0h” represents the current full hour air pressure recording. The
columns represent the “hPa” (0, ±2, ±4, ±6) at specific time. The “0” in the middle of this scale is
equal to the current pressure and each change (±2, ±4, ±6) represents how high or low in “hPa“ the
past pressure was compared to the current pressure.
If the bars are rising it means that the weather is getting better due to the increase of air pressure. If
the bars go down, it means the air pressure has dropped and the weather is expected to get worse
from the present time “0h“.
Note:
For accurate barometric pressure trends, the Weather Station should operate at the same altitude
for example, it should not be moved from the ground to the second floor of the house. Should the
unit be moved to a new location, discard readings for the next 12-24 hours.
OUTDOOR TEMPERATURE/HUMIDITY DATA
The
fourth
LCD section shows the outdoor temperature and humidity, the reception indicator,
the
transmitter identification number and
the MIN/MAX outdoor data
.
TOGGLING AND RESETTING THE OUTDOOR DATA
1.
To toggle between the outdoor current,
MAX/MIN
temperature and humidity data and the
times (for temperature data only) they were recorded press the
OUT/+
key:
Once to show the MAX outdoor temperature and humidity data with the recorded time and
date.
Twice to show the MIN outdoor temperature and humidity data with the recorded time and
date.
Three times to return to the current displayed values.
2.
Once the MIN or MAX data is displayed, press and hold the SET key for
3
seconds to reset
the
respective
MIN or MAX record to current temperature and humidity data,
and current time,
date display
.
Note:
The MIN or MAX data needs to be reset individually
.
BACK-LIGHT
The back-light is automatically switched ON when any keys are pressed. The back-light will be
switched on for approximately 8 seconds before automatically switching OFF.
ABOUT THE OUTDOOR TRANSMITTER
The range of the Thermo-hygro transmitter may be affected by the temperature. At cold
temperatures the transmitting distance may be decreased. Please bear this in mind when
positioning the transmitters. Also the batteries may be reduced in power for the Thermo-hygro
transmitter.
CHECKING FOR 433MHz RECEPTION
If the outdoor temperature and humidity data are not being received within three minutes after
setting up (or outdoor display show “- -. -” in the outdoor section of the Weather station after
3
failed
attempts during normal operation), please check the following points:
1.
The distance of the Weather station or transmitters should be at least
2 meters
away from any
interfering sources such as computer monitors or TV sets.
Air pressure over the last 24 hours
2.
Avoid placing the transmitters onto or in the immediate proximity of metal window frames.
3.
Using other electrical products such as headphones or speakers operating on the 433MHz-
signal frequency may prevent correct signal transmission or reception. Neighbors using
electrical devices operating on the 433MHz-signal frequency can also cause interference.
Note:
When the 433MHz signal is received correctly, do not re-open the battery cover of either the
transmitter or Weather station, as the batteries may spring free from the contacts and force a false
reset. Should this happen accidentally then reset all units (see
“Setting up”
above) otherwise
transmission problems may occur.
The transmission range is around
100
meters
from the Thermo-hygro transmitter to the Weather
station (in open space). However, this depends on the surrounding environment and interference
levels. If no reception is possible despite the observation of these factors, all system units have to
be reset (see
“Setting up”
above).
POSITIONING THE WEATHER STATION
The Weather station provides the option of table standing or wall mounting the unit. Before wall
mounting, please check that the outdoor data can be received from the desired locations.
To wall mount:
Outdoor transmitter identification number
1.
Fix a screw (not supplied) into the desired wall, leaving the head extended
out by about 5mm.
MIN icon
2.
Place the weather station onto the screw, using the hanging hole on the
backside. Gently pull the weather station down to lock the screw into place
.
Foldout table stand:
The foldout table stand leg is located on the backside. Pull the stand out from the
bottom center edge of the weather station, below the battery compartment. Once
