SETTING UP
Note: This weather station recei ves only one outdoor trans mitter.
1. First, insert the batteries i n the transmitter (see “How to install and replace batteries
in the thermo-hygro transmitter” above).
2. Within 30 seconds of poweri ng up the transmi tter, insert batteries in the weather stati on
(see “How to install and replace batterie s in the weather station ” abo ve). Once the
batteries are in place, all segments of the LCD wi ll light up briefl y and a short signal
tone will sound. Then the indoor temp erature, humi dity and the time as 0:00 will be
displayed. If these informatio n are not displ ayed on the LCD after 60 seconds, remov e
the batteries and wait for at l east 60 seconds before rei nserting them. Once the indo or
data is displayed user may proceed to t he next step.
3. After the batteries are inserted, t he weather stati on will start receiving data signal fro m
the transmitter. The outdoor temperat ure and humi dity data should then be displ ayed
on the weather station. If this does not happen after 2 mi nutes, the batteries will need
to be removed from both units a nd reset from step 1.
4. In order to ensure successful 868 MH z transmissi on, the distance between the weat her
station and the transmitter s hould be within 100 meters (se e notes on “Positioning ”
and “868 MHz Reception ”).
5. Once the outdoor data recepti on test period i s completed, the DCF tower icon in the
clock display will start fl ashing in the upper l eft corner. This indicates that the clock has
detected that there is a radi o signal present and i s trying to receive it. W hen the time
code is received, the DCF tower becom es perma nently lit and the time will be
displayed.
TO INSTALL AND REPLACE B ATTERIES IN THE WE ATHER STATION
The weather station uses 3 x AAA, IEC LR3,
1.5V batteries. To install and replace the
batteries, please foll ow the steps below:
1. Insert finger or other soli d object in the
space at the bottom center of t he
battery compartment and li ft up to
remove the cover.
2. Insert batteries observing the correct
polarity (see marking).
3. Replace compartment cover.
TO INSTALL AND REPLACE B ATTERIES IN THE THERM O-HYGRO
TRANSMITTER
The outdoor thermo-hygro tra nsmitter uses 2 x AAA, IEC L R3, 1.5V batteries. To
install and replace the batteri es, please foll ow the steps below:
1. Remove the battery cover by p ushing the battery cover upwards with your
thumb.
2. Insert the batteries, observi ng the correct pol arity (see battery
compartment marking).
3. Replace the battery cover on t he unit.
Note:
In the event of changing batteri es in any of the units, all units need to be reset by fol lowing
the setting up procedures. T his is due to a random sec urity code assigned by the tra nsmitter
at start-up. This code must be recei ved and stored by t he weather station in the first 3
minutes of power being suppl ied to the transmitter.
DCF RADIO CON TROLLED TIME
The time base for the radio co ntrolled time i s a Cesium Atomic Cl ock operated by the
Physikalisch Technische Bundesa nstalt Braunsc hweig which has a time deviati on of less than
one second in one milli on years. The time i s coded and transmitted from Mainfli ngen near
Frankfurt via frequency signal DCF-77 (77.5 kH z) and has a transmitti ng range of
approximately 1,500 km. Your radi o-controll ed weather station receives this si gnal and
converts it to show the precise ti me in summer or wi ntertime.
The quality of the reception depe nds greatl y on the geographic location. In normal cases,
there should be no receptio n problems within a 1,500 km r adius of Frankfurt.
DCF reception is done twice dai ly at 02:00 and 03:00 am. I f the reception is not succ essful at
03:00 am, then the next recepti on takes place t he next hour and so on until 06:00am, or until
the reception is successful. If t he reception is not s uccessful at 06:00 am, then the next
attempt will take pl ace the next day at 02:00 am.
If the tower icon flashes, but does not set the time or t he DCF tower does not appear at all,
then please take note of the fol lowing:
•
Recommended distance to a ny interfering sources l ike computer monitors or TV sets is
a minimum of 1.5 - 2 meters.
•
Within ferro-concrete rooms (baseme nts, superstructures), t he received signal i s
naturally weakened. In extreme cases, please pl ace the unit close to a window and/ or
point its front or back towards t he Frankfurt transmi tter.
•
During nighttime, the atmosp heric disturbances are usually l ess severe and reception is
possible in most cases. A singl e daily recepti on is adequate to keep the accuracy
deviation below 1 second.

WEATHER FOREC ASTING IC ONS:
The weather icons in the seco nd section of LCD ca n be displayed in any of the fol lowing
combinations:
For every sudden or signifi cant change in the air press ure, the weather icons will update
accordingly to represent the c hange in weather. If t he icons do not change, then i t means
either the air pressure has not c hanged or the cha nge has been too slow for the weat her
station to register. However, if t he icon displ ayed is a sun or raining cloud, there wi ll be no
change of icon if the weather gets a ny better (wi th sunny icon) or worse (with rainy icon) si nce
the icons are already at their e xtremes.
The icons displayed forecasts t he weather i n terms of getting better or worse and not
necessarily sunny or rainy as eac h icon indi cates. For example, i f the current weather is
cloudy and the rainy icon is di splayed, i t does not mean that the product is faulty bec ause it i s
not raining. It simply means that t he air pressure has dropped and the weather is e xpected to
get worse but not necessaril y rainy.
Note:
After setting up, readings for weat her forecasts s hould be disregarded for the next 1 2-24
hours. This will allow suffici ent time for the weat her station to coll ect air pressure data at a
constant altitude and therefore res ult in a more acc urate forecast.
Common to weather forecasti ng, absolute accuracy ca nnot be guaranteed. The weat her
forecasting feature is esti mated to have an accuracy l evel of about 75% due to the va rying
areas the weather station has bee n designed for use. In areas that experience sudde n
changes in weather (for exampl e from sunny to rai n), the weather station will be more
accurate compared to use i n areas where the weat her is stagnant most of the time (f or
example mostly sunny).
If the weather station is moved to a nother locati on significantly higher or lower than i ts initial
standing point (for example from t he ground fl oor to the upper floors of a house), di scard the
weather forecast for the next 12-24 hours. By doi ng this, the weather station will not mistake
the new location as being a possi ble change i n air-pressure when really i t is due to the slight
change of altitude.
WEATHER TENDE NCY INDIC ATOR
The weather tendency indicators (l ocated on the l eft side of the weather icons) are w orking
together with the weather ico ns. When the i ndicator points upwards, it means that t he air-
pressure is increasing and the weat her is expected to i mprove, but when indicator p oints
downwards, the air-pressure i s dropping and the weat her is expected to become wor se.
Taking this into account, one ca n see how the weat her has changed and is expected to
change. For example, i f the indicator is pointing dow nwards together with cloud and sun
icons, then the last noticeabl e change in the weat her was when it was sunny (the s un icon
only). Therefore, the next cha nge in the weather wi ll be cloud with rain icons since t he
indicator is pointing downwards.
Note:
Once the weather tendency i ndicator has regi stered a change in air pressure, it wil l remain
permanently visuali zed on the LCD.
AIR PRESSURE HIS TORY (ELEC TRONIC B AROMETER WI TH BAROMET RIC
PRESSURE TREND )
The right side of the second secti on of the LCD s hows the air pressure history bar gr aph.
The bar graph indicates the ai r pressure history tre nd over the last 12 hours in 7 i ntervals: 0h,
-3h, -6h, -9h and -12h. The “0 h” represents the c urrent full hour air pressure recordi ng. The
columns represent the “hPa” (0, ±1, ±3, ± 5) at specifi c time. The “0” in the middle of this scal e
is equal to the current pressure a nd each change (±1, ±3, ± 5) represents how high or l ow in
“hPa“ the past pressure was compared t o the curre nt pressure.
If the bars are rising it means t hat the weather is getti ng better due to the increase of air
pressure. If the bars go down, i t means the ai r pressure has dropped and the weat her is
expected to get worse from the prese nt time “0 h“.
Note:
•
For accurate barometric press ure trends, the weat her station should operate at the
same altitude for recordings (i .e. it should not be moved fr om the ground to the seco nd
floor of the house). W hen the unit is moved to a new location, discard readings for t he
next 12 hours.
•
The level of the pressure bar wi ll be affected by t he temperature change and it i s for
reference only.
