and replace the batteries, please follow the steps below:
1. Remove the cover.
2. Insert the batteries, observing the correct polarity (see marking).
3. Replace the battery cover.
Note:
In the event of changing batteries in any of the units, all units need to be reset by

20
following the setting up procedures. This is due to a random security code assigned by the
transmitter at start-up. This code must be received and stored by the Weather Station in the first 3
minutes of power being supplied to the transmitter.
BATTERY CHANGE:
It is recommended to replace the batteries in all units on an annual basis to ensure optimum
accuracy of these units.
Please participate in the preservation of the environment. Return used batteries
to an authorized depot.
SETTING UP
WHEN ONE TRANSMITTER IS USED
1. First, insert the batteries in the transmitter (see “How to install and replace batteries in the
Termo-hygro outdoor transmitter” above).
2. Within 2 minutes of powering up the transmitter, insert the batteries in the Temperature
Station (see “How to install and replace batteries in the Weather Station” above). Once
the batteries are in place, all segments of the LCD will light up briefly and a short signal tone
will sound. Following the indoor temperature/humidity and the time as 0:00 will be displayed.
If these information are not displayed on the LCD after 60 seconds, remove the batteries and
wait for at least 60 seconds before reinserting them. Once the indoor data is displayed user
may proceed to the next step.
3. After the batteries are inserted, the Weather station will start receiving data signal from the
transmitter. The outdoor temperature and humidity data 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.
4. In order to ensure sufficient 868 MHz transmission however, the distance between the
Weather Station and the transmitter should not be more than 100 meters (see notes on
“Positioning” and “868 MHz Reception”).
Note:
In the event of changing batteries of the units, ensure the batteries do not spring free from the
contacts. Always wait at least 1 minute after removing the batteries before reinserting, otherwise
start up and transmission problems may occur.
WHEN MORE THAN ONE TRANSMITTER IS USED
1. User shall remove all the batteries from the Weather Station and transmitters, and wait 60
seconds.
2. Insert the batteries in the first transmitter.
3. Within 2 minutes of powering up the first transmitter, insert the batteries in the Weather
Station. Once the batteries are in place, all segments of the LCD will light up briefly and a
short signal tine will sound. Following the indoor temperature/humidity and the time as 0:00
will be displayed. If these information are not displayed on the LCD after 60 seconds, remove
the batteries from both units and wait for at least 60 seconds before reinserting them.
4. The outdoor temperature and humidity data from the first transmitter (channel 1) should then
be displayed on the Weather Station. 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.
5. Insert the batteries in the second transmitter as soon as the outdoor temperature and
humidity readings from the first transmitter are displayed on the Weather Station.
Note : User shall insert the batteries into the second transmitter within 45 seconds after the
Weather Station displays the information of the first transmitter.
6. The outdoor temperature and humidity from the second transmitter and the "channel 2" icon
should then be displayed on the Weather Station. If this does not happen after 2 minutes, the
batteries will need to be removed from all the units and reset from step 1.

21
7. Insert the batteries in the third transmitter as soon as the "channel 2" icon and outdoor data
are displayed on the Weather Station. Then within 2 minutes, the channel 3 outdoor data
from the third transmitter will be displayed and the channel icon will shift back to "1" once the
third transmitter is successfully received. If this is not happen, user shall restart the setting up
from step 1.
Note : User shall insert the batteries into the third transmitter within 45 seconds after the
Weather Station displays the information of the first transmitter. Or immediately after
reception of the second transmitter is finished.
8. In order to ensure sufficient 868 MHz transmission however, the distance between the
Weather Station and the transmitter should not be more than 100 meters (see notes on
“Positioning” and “868 MHz Reception”).
IMPORTANT:
Transmission problems will arise if the setting for additional sensors is not followed as described
above. Should transmission problems occur, it is necessary to remove the batteries from all units
and start again the set-up from step 1.
RESETTING
The Weather Station and the Thermo-hygro transmitter need to be reset when one of the following
conditions occur:
• Unsuccessful 868 MHz signal reception.
• Malfunction on the units.
• Batteries replacement.
For resetting, remove all batteries from the units. Wait at least for 1 minute before powering up the
Weather station again. Proceed from step 1 in “Setting Up”.
DCF RADIO CONTROLLED TIME
The time base for the radio controlled time is a Cesium Atomic Clock operated by the Physikalisch
Technische Bundesanstalt Braunschweig which has a time deviation of less than one second in
one million years. The time is coded and transmitted from Mainflingen near Frankfurt via
fre uency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. Your
radio-controlled Weather Station receives this signal and converts it to show the precise time in
summer or wintertime.
The uality of the reception depends greatly on the geographic location. In normal cases, there
should be no reception problems within a 1500km radius of Frankfurt.
DCF reception occurs twice daily at 02:00 and 03:00 am. If the reception is not successful at 03:00
am, then the next reception takes place the next hour and so on until 06:00am, or until the
reception is successful. If the reception is not successful at 06:00 am, then the next attempt will
take place the next day at 02:00 am.
Once the outdoor data reception test period is completed, the DCF tower icon in the clock display
will start flashing in the upper left corner. This indicates that the clock has detected that there is a
radio signal present and is trying to receive it. When the time code is received, the DCF tower
becomes permanently lit and the time will be displayed.
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all, 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 ade uate 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:
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 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 in 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 rainy.
Note:
After setting up, readings for weather forecasts should be disregarded for the next 12-24 hours.
This will allow sufficient time for the Weather station to collect air 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 varying 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 location significantly higher or lower than its initial
standing point (for example from the ground floor to the upper floors of a house), discard the
weather forecast for the next 12-24 hours. 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.
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.

29
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
e ual 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.

2. Use OUT/+ key to view the MIN/MAX temperature and humidity data for the selected
transmitter.
3. To reset the minimum and maximum temperature and humidity data, and the times at which
they were recorded, press the SET key continuously for about 3 seconds. This will reset the
MIN/MAX data recorded to the current time, date, temperature and humidity. The current
time taken is the normal displayed time and does not regard the time zone set for the unit.
Note: the MIN/MAX data for each transmitter needs to be reset separately.
LOW BATTERY INDICATOR
Low battery indicator is displayed on the LCD when the batteries re uire changing.
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 868MHz RECEPTION
If the outdoor temperature and humidity data are not being received within three minutes after
setting up (or outdoor display always show “- -. -” in the outdoor section of the Weather station
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.
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 868MHz-
signal fre uency may prevent correct signal transmission or reception. Neighbors using
electrical devices operating on the 868MHz-signal fre uency can also cause interference.
Note:
When the 868MHz 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:
1. Fix a screw (not supplied) into the desired wall, leaving the head extended
out by about 5mm.
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.

31
Foldout table stands:
The foldout table stands legs are located on the backside.
Simply unfold the stands on the back. Once the foldout table
stands are extended, place the weather station in an
appropriate location.
POSITIONING THE THERMO-HYGRO TRANSMITTER
The Thermo-hygro transmitter is supplied with a holder that may be attached to a wall
with the three screws supplied. Before securing the transmitter, ensure that the
868MHz signal is properly received. To attach to the wall, please follow the steps
below:
1. Mark the wall using a pen through the holes in the holder to obtain the exact
drilling position.
2. Drill holes in the wall at the points marked.
3. Screw holder onto wall.
There is also double sided tape included with the wall mount. On smooth surfaces this can be used
instead of drilling holes. The mounting surface can, however, affect the transmission range. If for
example the unit is attached to a piece of metal, it may then either reduce or increase the
transmitting range. For this reason, we recommend not placing the unit on any metal surfaces or in
any position where a large metal or highly polished surface is in the immediate proximity (garage
doors, double glazing, etc.). Before securing in place, please ensure that the Weather station can
receive the 868MHz signal from the Thermo-hygro transmitter at the positions that you wish to
situate them.
The Thermo-hygro transmitter simply clicks in or out of the holder. When inserting or removing the
Thermo-hygro transmitter from the wall holder please hold both units securely.
CARE AND MAINTENANCE:
• Extreme temperatures, vibration and shock should be avoided as these may cause damage
to the units and give inaccurate forecasts and readings.
• When cleaning the display and casings, use a soft damp cloth only. Do not use solvents or
scouring agents as they may mark the LCD and casings.
• Do not submerge the units in water.
• Immediately remove all low powered batteries to avoid leakage and damage. Replace only
with new batteries of the recommended type.
• Do not make any repair attempts to the units. Return it to their original point of purchase for
repair by a ualified engineer. Opening and tampering with the units may invalidate their
guarantee.
• Do not expose the units to extreme and sudden temperature changes, this may lead to rapid
changes in forecasts and readings and thereby reduce their accuracy.
