INSTALL AND REPLACE BATTERIES IN THE TEMPERATURE TRANSMITTER

The temperature transmitter uses 2 x AAA, IEC LR3, 1.5V batteries.
To install and replace the batteries, please foll ow the steps below:

1. Remove the battery compartment cover.

2. Insert the batteries, observing the correct pol arity (see marking).

3.

Replace the battery compartment cover.

INSTALL AND REPLACE BATTERIES IN THE WEATHER STATION

The weather station uses 2 x AA, IEC LR6, 1.5V batteries. To install and replace the
batteries, please follow the steps below:

46

1. Insert finger or other solid object in the space at the
bottom center of the battery compartment and lift up to
remove the cover.

2. Insert batteries observing the correct polari ty (see
marking).

3. Replace compartment cover.

Battery replacement

•

Replace the batteries when the battery symbol of the weather station appears above
the indoor humidity.

•

When the batteries of the transmitter are used up, the low battery icon appears above
the outdoor temperature display.

Note:

In the event of changing batteries in any of the units, all units need to be reset by following
the setting up procedures. This is because a security code is assigned by the temperature

47

transmitter at start-up and this code must be received and stored by the weather stati on in
the first 3 minutes of power being supplied to i t.

SETTING UP:

When one temperature transmitter is used:

1. First, insert the batteries into the temperature transmitter (see “Install and replace
batteries in the temperature transmitter” above).

2. Within 30 seconds of powering up the temperat ure transmitter, insert the batteries to
the weather station (see “Install and replace batteries in the weather station”
above). Once the batteries are in place, all segments of the LCD will light up briefly.
Then the indoor temperature and the time as 0:00 will be displayed. If they are not
shown on LCD after 60 seconds, remove the batteries and wait for at least 60
seconds before reinserting them. Once the i ndoor data is displayed, proceed to the
next step.

3. After the batteries are inserted, the weather station will start receiving data signal from
the temperature transmitter.

4. If the optional probe has been plugged to the dual channel transmitter, the outdoor
temperature should then be displayed on the weat her station on channel 1 and 2.
Also, the signal reception icon will be displayed. If this does not happen after 2
minutes, the batteries will need to be removed from both units and reset from step 1.

48

Note:

Channel 1 will show the reading from the internal sensor of the dual channel transmitter;
channel 2 will show the reading sensed by the probe. If the probe is not plugged to the
transmitter, " - -" will be shown on channel 2.

5. In order to ensure sufficient 868 MHz transmission, the final position between the
weather station and the temperature transmi tter should not be more than 100 meters
(see notes on “Positioning” and “868 MHz reception”).

6. Once the remote temperature has been recei ved and displayed on the weather
station, the DCF time code reception is automatically started. This takes typically
between 3-5 minutes in good conditions. If the DCF time not received within 10
minutes, press the SET button to adjust the ti me manually.

When two temperature transmitters are used

1. Remove all the batteries from the weather station and temperature transmitters and
wait 60 seconds (if setting has been done wi th one temperature transmitter before).

2. Insert the batteries into the first temperature transmitter.

3. Within 30 seconds of powering up the first temperature transmitter, insert the batteries
into the weather station. Once the batteries are i n place, all segments of the LCD will
light up briefly. Then the indoor temperature and the time as 0:00 will be displayed. If

49

they are not shown on the LCD after 60 seconds, remove the batteries and wait for at
least 60 seconds before reinserting them.

4. If the probe sensor has been installed to the first temperature transmitter, the outdoor
temperature readings from the first temperature transmitter (channel 1 and 2) should
then be displayed on the weather station. If this does not happen after 2 minutes, the
batteries will need to be removed from both units and reset from step 1.

5. Insert the batteries into the second temperature transmitter as soon as the outdoor
temperatures from the first temperature transmitter are displayed on the weather
station.

Note: Insert the batteries into the second transmitter within 20 seconds of reception of the
first temperature transmitter.

6. After the weather station has received the seco nd temperature transmitter
successfully, channel 3 will only show the data, which will be measured by the internal
sensor of the second dual channel transmitter. T he measuring data of the external
probe of the second temperature transmitter will not be shown on the display of the
weather station. The outdoor temperature readi ng from the second temperature
transmitter will be shown on the display of the weather station and the shown channel
number will be shift back to “1”, to indicate that all three channels are running
successfully. If this does not happen within 2 mi nutes, the batteries will need to be

50

removed from all the units and reset from step 1.

6. Once the external data has been received and di splayed on the weather station, the

DCF time code reception is automatically started. This takes typically between 3-5
minutes in good conditions.

NOTE FOR RADIO-CONTROLLED TIME DCF:

The time base for the radio-controlled time i s a caesium atomic clock operated by the
Physikalisch Technische Bundesanstalt Braunschweig. It has a time deviation of less than
one second in one million years. The time i s coded and transmitted from Mainflingen near
Frankfurt via frequency signal DCF-77 (77.5 kHz) and has a transmitting range of
approximately 1,500 km. Your radio-controll ed clock receives this signal and converts it to
show the precise time. Changeover from summer time or winter time is automatic. The
quality of the reception depends mainly on the geographic location. Normally there should
be no reception problems within a 1,500 km radius around Frankfurt.

DCF reception is done twice daily at 02:00 and 03:00 am. If the reception is not successful
at 03:00 am, then the next reception takes pl ace the next hour and so on until 06:00am, or
until the reception is successful. If the recepti on is not successful at 06:00 am, then the ne xt
attempt will take place the next day at 02:00 am.

51

If the tower icon flashes, but does not set the time or the DCF tower does not appear at all ,

IN button

then please take note of the following:

•

Recommended distance to any interfering sources like computer monitors or TV sets
is a minimum of 1.5 - 2 meters.

•

Within ferro-concrete rooms (basements, superstructures), the received signal is
naturally weakened. In extreme cases, please place the unit close to a window and/ or
point its front or back towards the Frankfurt transmitter.

•

During nighttime, the atmospheric disturbances are usually less severe and reception
is possible in most cases. A single daily reception is adequate to keep the accuracy
deviation below 1 second.

WEATHER FORECAST AND WEATHER TENDENCY:
WEATHER FORECASTING ICONS:

Weather icons in the third section of LCD can be displayed in any of the following
combinations:

61

Digit flashing

For every sudden or significant change in the atmospheric pressure, the weather icons will
update accordingly to represent the change i n weather. If the icons do not change, then it
means either the atmospheric pressure has not changed or the change has been too slow
for the weather station to register. However, if the icon 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 i n terms of getting better or worse and not
necessarily sunny or rainy as each icon indi cates. For example, if the current weather is
cloudy and the rainy icon is displayed, it does not mean that the product is faulty because i t
is not raining. It simply means that the atmospheric pressure has dropped and the weather is
expected to get worse but not necessarily rainy.

Sunny

Cloudy with sunny intervals Rainy

62

Note:
After setting up the weather station the readi ngs for weather forecasts should be
disregarded for the next 12-24 hours. This will allow sufficient time for the weather station to
collect atmospheric pressure data 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 varyi ng
areas the weather station has been designed for use. 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 locati on significantly higher or lower than its i nitial
standing point (for example from the ground fl oor to the upper floors of a house), discard t he
weather forecast for the next 12-24 hours. By doing this, the weather station will not mi stake
the new location as being a possible change i n atmospheric pressure when really it is due to
the slight change of altitude.

63

WEATHER TENDENCY INDICATOR

Working together with the weather icons is the weather tendency indicators (located on the
right sides of the weather icons). When the i ndicator points upwards, it means that the
atmospheric pressure is increasing and the weather is expected to improve, but when
indicator points downwards, the atmospheri c 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 weat her was when it was sunny (the sun ico n
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 regi stered a change in atmospheric pressure, i t will
remain permanently visualized on the LCD.

ABOUT THE OUTDOOR TRANSMITTER

The outdoor temperature is measured and transmitted every 4 seconds.
The range of the temperature transmitter may be affected by the temperature. At cold
temperatures the transmitting distance may be decreased. Please keep this in mind when
placing the transmitter.

868 MHz RECEPTION

If the outdoor temperature data is not recei ved 5 minutes after setting up (the outdoor
display shows “- - -” ), please check the following points:

1. The distance of the weather station or transmitter should be at least 1.5 to 2 meters
away from any interfering sources such as computer monitors or TV sets.

2. Avoid positioning the weather station onto or i n the immediate proximity of metal
window frames.

3. Using other electrical products such as headp hones or speakers operating on the
same signal frequency (868MHz) may prevent correct signal transmission and
reception.

69

4. Neighbours using electrical devices operati ng on the 868MHz signal frequency can
also cause interference.

Note:
When the 868MHz signal is received correctly, do not re-open the battery cover of either the
temperature transmitter or weather station, as the batteries may spring free from the
contacts and force a false reset. Should thi s happen accidentally then reset all units (see
Setting up above) otherwise transmission problems may occur.
The transmission range is about 100 m from the temperature transmitter to the weather
station (in open space). However, this depends on the surrounding environment and
interference levels. If no reception is possibl e despite the observation of these factors, all
system units have to be reset (see Setting up).

POSITIONING THE WEATHER STATION:

The weather station may be hung onto wall easily or free standing.

70

To wall mount

Before wall mounting, please check that the outdoor temperature values
can be received from the desired locations.

1. Fix a screw (not supplied) into the desired wall, leaving the head
extended out the by about 5mm.

2. Hang the station onto the screw. Remember to ensure that it locks
into place before releasing.

min

Free standing

With the foldout stand, the weather station can be placed onto any flat
surface.

71

POSITIONING THE TEMPERATURE TRANSMITTER:

The temperature transmitter is supplied with a holder that may be
attached to a wall with the two screws suppli ed. The temperature
transmitter can also be position on a flat surface by securing the stand
to the bottom of the temperature transmitter.

To wall mount:

1. Secure the bracket onto a desired wall using the screws and
plastic anchors.

2. Clip the temperature transmitter onto the bracket.

Note:
Before permanently fixing the temperature transmitter wall base,
place all units in the desired locations to check that the outdoor
temperature reading is receivable. In event that the signal is not

72

received, relocate the temperature transmitters or move them slightly as this may help the
signal reception.
