Getting Started

Insert the batteries

Place the base station and all transmitter on a table at a distance of about 1.5 meters from each other.
Avoid being close to possible sources of interference such as electronic devices and radio equipment.

Temperature-humidity sensor

Open the battery compartment of the temperature-humidity sensor (Fig.2-H) and insert two new AA 1.5 V batteries, polarity as illustrated. All LCD segments will be displayed for a short moment.

The transmitter’s display shows the current temperature and humidity (Fig.2-C+D). The switch is set to channel 1 (Fig.2-G).
Close the battery compartment.

Rain sensor

Open the two tabs (Fig.3-B) on each side of the rain sensor and lift the funnel portion (Fig.3-A) off the base (Fig.3-C).
Open the battery compartment (Fig.3-D) and insert two new AA 1,5 V batteries. Make sure the polarities are correct (see marking on the cover).
Close the battery compartment.

Remove the transport lock of the rocker (Fig.3-E).
Close the housing cover and lock it.

Wind sensor

Mount the wind sensor (Fig.4-E) on the adjustable base (Fig.4-H). Tighten the two screws (Fig.4-F).
Open the battery compartment at the bottom of the device (Fig.4-G) and insert three new batteries 1,5 V AA, polarity as illustrated.
Close the battery compartment.

With the solar panel (Fig.4-B) the battery life will be extended.
The LED signal light (Fig.4-C) is flashing.

Base station

Remove the protective film from the base station display.
Insert the three new batteries 1,5 V AA into the battery compartment (Fig.1-R) of the base station.
Make sure the polarities are correct.
The device will alert you with a beep and all LCD segments will be displayed for a short moment.

The indoor temperature and humidity appear on the display (Fig.1-A1+A2).

Outdoor values reception

After the batteries are inserted, the outdoor values of the outdoor sensors will be transmitted to the base station.

The base station will scan the outdoor values of the transmitters. The reception symbols of the temperature humidity sensor (Fig.1-C7), the wind sensor (Fig.1-E1) and the rain sensor (Fig.1-D1) are flashing.
If reception is successful, beeps sound and the outdoor values are permanently displayed.
Outdoor temperature and humidity appear on the display (Fig.1-C3+C4).

The rainfall amount (initially 0.0 mm) (Fig.1-D5) and the wind speed (initially 0.0 km/h) (Fig.1-E5) are displayed. To simulate values, move the rocker (Fig.3-E) or the wind wheel (Fig.4-A) (transmission time rain sensor: 90 seconds, wind sensor: 31 seconds).
If the reception of the outdoor values fails within three minutes, “- -“ appears on the display. Check the batteries and try it again. Check if there is any source of interference.
You can also start the outdoor transmitters search manually later (e.g. if the transmitter is lost or if the batteries are changed):
- Press and hold the CHANNEL button (Fig.1-N) for three seconds to search for the temperature-humidity sensor. Press the TX button (Fig.2-F)button in the transmitter’s battery compartment (Fig.2-H).
- Press and hold the RAIN button (Fig.1-G) for three seconds to search for the rain sensor.
- Press and hold the WIND button (Fig.1-H) for three seconds to search for the wind sensor.
- A beep will sound. The registered transmitter will be cancelled. The reception symbol of the transmitter flashes and the base station will scan the outdoor values.

Reception of the DCF frequency signal

After the reception of the outdoor values, the clock will now scan the DCF frequency signal and the DCF symbol flashes on the display (Fig.1-B1).

When the time code is successfully received after 3-10 minutes, the radio-controlled time and the DCF symbol will be shown steadily on the display.
The DCF reception always takes place at 1:00 and 2:00 o’clock in the morning. If the reception was not successfully received, further attempts will be taken at 3:00, 4:00 and 5:00 o’clock.
You can also activate the DCF reception manually. Press the SET button (Fig.1-M).
The DCF reception symbol flashes.
- There are 3 different reception symbols:
  - flashing symbol: reception is active
  - solid: reception is successful
  - no symbol: no DCF reception
If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting distance, etc.), the time can be set manually.
The clock will then work as a normal quartz clock (see: “Manual settings”).

Note on radio-controlled time

The time is transmitted from an atomic clock near Frankfurt am Main by a DCF-77 (77.5 kHz) frequency signal with a range of about 1,500 km. Your radio-controlled clock receives the signal, converts it and always shows the exact time. The adjustment of Daylight Saving Time and Standard Time is also automatic.
During night-time, the atmospheric interference is usually less severe. A single daily reception is adequate to
keep the accuracy deviation under 1 second. In extreme cases, please place the unit close to a window to improve reception.

Operation

During the operation, all successful settings will be confirmed by a brief beep tone. Provided that in the setting mode the button tone is activated (BEEP ON).
The device will automatically quit the setting mode if no button is pressed for 10 seconds.
Press the ALERTS button (Fig.1-O) to quit the setting mode.

Press and hold the + or – button (Fig.1-K+L) in setting mode for fast mode.

Manual settings

Press and hold the SET button (Fig.1-M) for three seconds to enter the setting mode.

Beep ON (default) flashes on the display. Press the + or – button (Fig.1-K+L) to deactivate (OFF) or activate again the button tone.
Confirm the setting with the SET button.
The next adjustable value flashes on the display.

Use the + or – button to make the desired setting.
Confirm with the SET button and go to the next setting.
- The sequence is shown as follows:
  - Button tone ON/OFF (default: BEEP ON)
  - DCF reception ON/OFF (default: DCF ON)
  - Time zone -12/+12 (default: 0H)
  - Hour, minute (Fig.1-B2)
  - Year, month, day (Fig.1-B3)
  - Atmospheric pressure setting (default: 1013 hPa) (Fig.1-F2)
  - Unit of the wind speed (km/h (default), m/s or bft) (Fig.1-E5)
  - Average wind speed (AVG 10, default) or maximum wind speed (TOP 1HR) (Fig.1-E6)
  - Prevailing wind direction, optionally as cardinal points (default) or degrees (Fig.1-E4)
  - Day-of-week language (default: GER) (Fig.1-B3)

DCF reception

By default, the DCF reception is activated (DCF ON) and after successful reception of the DCF signal no manual time setting is necessary.

Once the DCF time reception is deactivated (DCF OFF) the clock must be manually set.
If the DCF reception is activated, the manually set time will be overwritten by the DCF time when the signal is received successfully.

Time zone setting

In the setting mode you can make the time zone correction
The time zone correction is needed for countries where the DCF signal can be received but the time zone is different from the DCF time (e.g. +1=one hour plus).

Atmospheric pressure setting

The relative atmospheric pressure (Fig.1-F2) is referred to the sea level’s pressure and has to be adjusted first to your local altitude. Ask for the current atmospheric pressure of your home area (Local weather service, Internet, optician, calibrated instruments in public buildings and airport).

Day-of-week language setting

In the setting mode you can choose the day-of-the-week language.

Day-of-the-week language: German (GER), English (ENG), French (FRE), Italian (ITA), Dutch (DUT), Spanish (SPA), Swedish (SWE) and Czech (CZE).

Temperature And Humidity

Trend arrows

The trend arrows (Fig.1-A4+C8) indicate whether the values for temperature and humidity of the last 15 minutes are increasing, steady or decreasing.
Temperature/humidity are increasing
Temperature/humidity are steady (change < 0.5°C/2%)
Temperature/humidity are decreasing

Maximum and minimum values

Press several times the TEMP button (Fig.1-J) button in normal mode.

You can now see the highest (HI) and lowest values (LO) (Fig.1-A3+C5) ) since the last reset with time and date of recording.
The sequence is shown as follows: Indoor temperature (HI/LO), indoor humidity (HI/LO), outdoor temperature (HI/LO), outdoor humidity (HI/LO).
If you have connected more than one temperature-humidity sensor, the highest and lowest values for additional channels appear.

Press the TEMP button once more, to go back to the current values display.
The device will automatically quit the HI/LO mode if no button is pressed.
Press and hold the – button (Fig.1-L) for 3 seconds while the maximum or minimum values are displayed to clear the recorded readings (display – -).

Forecast

Weather forecast symbols

The weather station has five different weather symbols (sunny, slightly cloudy, cloudy, rainy, stormy). (Fig.1-F3).

The weather forecast relates to a range of 12 to 24 hours and indicates only a general weather trend.
For example, if the current weather is cloudy and the rain symbol is displayed, it does not mean 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.

Trend arrows

The trend arrows on the display will show whether the atmospheric pressure of the last 3 hours is increasing, steady or decreasing.
Increase (+1-2 hPa): Weather improvement
Fast increase (>+2hPa): Significant weather improvement
Steady (+-1hPa): Stable weather conditions
Decrease (-1-2 hPa): Weather deterioration
Fast decrease (>-2hPa): Significant weather deterioration

Atmospheric pressure

The relative atmospheric pressure (Fig.1-F2) is referred to the sea level’s pressure and has to be adjusted first to your local altitude (see: “Manual settings”).

Developing of atmospheric pressure

The bar graph indication (Fig.1-F1) of atmospheric pressure shows the last 24 hours.
The “0h” 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 (Fig.1-F2) .
If the bars go down, it means the atmospheric pressure has dropped and the weather is expected to get worse.
If the bars are rising it means that the weather is getting better

Wind

Wind speed

The wind wheel symbol (Fig.1-E2) is animated when it is windy and moves according to the wind speed:
One loop per 2 seconds: Wind speed < 5 km/h
One loop per second: Wind speed > 5km/h
In the setting mode you can select the unit of the wind speed in km/h (default), m/s or Beaufort (see “Manual settings”).
The current wind speed (WINDSPEED) (Fig.1-E5) corresponds to the average value of 5 seconds. The maximum value is transmitted every 31 seconds.
In the setting mode, you can select between the average wind speed of the last 10 minutes (AVG 10, default setting) or the maximum wind speed of the last hour (TOP 1HR) as the permanent display (see “Manual settings”).
Press the WIND button (Fig.1-H) in normal mode to display the maximum wind speed for different time intervals, indicating the time and date of recording:
- Maximum wind speed of the last 24 hours (24 HRS)
- Maximum wind speed of the last 7 days (7 DAYS)
- Maximum wind speed of the last month (MONTH). You can toggle through the past 11 months of maximum wind speed history when you are in MONTH view by pressing the + button (Fig.1-K).
- Maximum wind speed of the current year (YEAR).
NOTE: Hold the – button (Fig.1-L) for 3 seconds in the respective wind speed display to clear the recorded readings. Every display can be reset individually.
The device will automatically quit the mode if no button is pressed for 5 seconds.

Wind direction

The large triangle on the LCD wind rose (Fig.1-E9) indicates the wind direction (16 wind directions).
In addition, the PREVAILING DIRECTION (Fig.1-E4) of the last hour is displayed. In the setting mode, you can choose between showing the cardinal direction or the number of degrees on the display (see “Manual settings”).

“Feels Like” temperature (WIND CHILL)

Wind Chill (Fig.1-E8) is a calculative value of outdoor temperature (of CH1) and wind speed.
Note: The wind chill calculator only works for temperature at or below 10°C and wind speeds above 4.83 km/h (3 mph), otherwise the current outdoor temperature is displayed.

Rain

Rainfall amount indication

The rainfall amount of today (since 0:00h) (Fig.1-D5) is shown in mm and on a corresponding graph (Fig.1-D4). If the display range of the daily rainfall for the graph is exceeded (>30 mm), the symbol “>” appears above the 30mm indication.
When it starts to rain the rain drop symbol (Fig.1-D3) begins to flash. If there is no precipitation for 30 minutes, the drops are no longer displayed.
Press the RAIN button (Fig.1-G) in normal mode to switch between the rainfall displays for different time intervals (Fig.1-D7):
The last selected display is permanently active (default 24 HRS).
- Rainfall amount of the last hour (1HR)
- Rainfall amount of the last 24 hours (24HRS)
- Rainfall amount of the last 7 days (7 DAYS)
- Rainfall amount of the last month (MONTH). You can toggle through the past 11 months of rainfall history when you are in MONTH view by pressing the + button (Fig.1-K).
- Rainfall amount of the last year (YEAR)
- Indication of TOTAL rainfall amount since setting up or the last reset.
NOTE: Hold the – button (Fig.1-L) for 3 seconds in the respective rainfall amount indication to clear the recorded readings. Every rainfall amount indication can be reset individually.

To activate (ON) or deactivate (OFF) the alert setting function, press the + or – button (Fig.1-K+L) while ON or OFF flashes.
If you have activated the alert (ON), wait some seconds until the alert value flashes.
Press + or – button to adjust the respective alert value.
Confirm with the ALERTS button and go to the next setting.
The sequence is shown as follows:
Upper limit wind speed (1…178 km/h)
- 24-hour rainfall (1…990mm)
  - Lower (LO) and upper limit (HI) indoor temperature (0…50°C)
  - Lower (LO) and upper limit (HI) indoor humidity (10…99%RH)
  - Lower (LO) and upper limit (HI) outdoor temperature CH1 (-40…60°C)
  - Lower (LO) and upper limit (HI) outdoor humidity CH1 (10…99%RH)
If you have connected more than one temperature-humidity sensor, the alert setting for additional channels appears.
When activated, the corresponding alert symbols ( ) appear on the display.

Alarm event

In the event of an alarm, the corresponding symbol ( ) will be flashing and an alarm tone will sound 5 times per minute.
Stop the alarm sound with any button.
The alert symbol continues to flash until the measured value is within the alarm limits.

Mounting

Base station positioning

With the foldable leg at the back (Fig.1-S) , the base station can be placed onto any flat surface.
The base station can be wall mounted at a chosen location by the mounting holes found at the back of the unit (Fig.1-P). Make sure to avoid the vicinity of any source of interference such as computer screens, TV sets or solid metal objects. Within solid walls, especially ones with metal parts, the transmission range can be reduced considerably.
Do not use the product in the vicinity of radiators, other sources of heat or in direct sunlight.

Installation of the transmitters

Before the final installation, make sure that the measured values are transmitted from the transmitter at the desired installation site to the base station in the living area.
Also make sure that the transmitters are easily accessible for cleaning and maintenance. The outdoor transmitters should be cleaned from time to time, since dirt and debris will affect the sensor’s accuracy.

Temperature-humidity sensor (Fig.2)

When placed outdoors, choose a shady and dry place for the temperature-humidity sensor. Direct sunlight may trigger incorrect measurement and continuous humidity damages the electronic components needlessly.

Rain sensor (Fig.3)

Place the rain sensor horizontally in an area where rain can fall directly into the container, ideally 60 to 90 cm above the ground on a small platform.
You can tighten the rain sensor in the desired position with four screws (Fig.3-F).

Wind sensor (Fig.4)

Make sure that the wind can blow freely around the wind sensor and is not blocked by nearby buildings, trees or any other objects.
For best results, we recommend mounting the wind sensor on a mast, ideally 3 metres above any obstructions.
Try to install the wind sensor so that it will be exposed to the normal wind conditions in your area.
Attach the delivered adjustable base (Fig.4-H) to a mast (ø 25-28mm). Matching metal brackets and nuts are included in the scope of delivery.
The adjustable base can also be attached to a surface. First screw the base in the desired position with the four screws (Fig.4-K). The adjustable base may be rotated by 90°/180°. Open the fixing screw (Fig.4-J) and loosen the adjustable base (Fig.4-H). Turn it in the desired position and tighten the fixing screw again.
Make sure that the adjustable base is securely fastened.
Then place the wind sensor on the adjustable base (Fig.4-E) and fix it with the screws (Fig.4-F).
The wind wheel points upwards and the wind vane downwards.
Ensure the wind sensor is mounted level with the solar panel (Fig.4-B) facing directly to the South. This will help optimize battery life and transmit correct wind direction. Use a compass if necessary.

Additional outdoor transmitters (optional) Cat.-No. 30.3249.02

When having more than one temperature-humidity sensor, select a different channel for each one with the CH 1/2/3 switch (Fig.2-G) inside the transmitter’s battery compartment. Insert two new AA 1.5 V batteries, polarity as illustrated. Start the base station operation or the manual search for the outdoor transmitters.
The outdoor values and the channel number will be shown on the base station display (Fig.1-C2). If you have installed more than one temperature-humidity sensor, press the CHANNEL button (Fig.1-N) on the base station to change between the channels 1 to 3.
You can also choose an alternating channel display. Press CHANNEL button. After the last registered channel (1 to 3) a circle symbol (Fig.1-C1) will appear. To deactivate the function press the CHANNEL button again.
After a successful installation close the outdoor transmitter’s battery compartments carefully.

Care And Maintenance

Clean the devices with a soft damp cloth. Do not use solvents or scouring agents.
Make sure that the wind cups and the vane can spin freely and are free from dirt, debris or spider webs.
Check and clean the rain gauge periodically for optimum performance of the rainfall measurement. The funnel should be routinely cleaned and freed from leaves and dirt.
Remove the batteries if you do not use the devices for a long period of time.

Battery Replacement

As soon as the corresponding battery symbols appears in the display, please change the batteries of the base station (Fig.1-B4) or transmitters (Fig.1-C6, Fig.2-E, Fig.1-D2, Fig.1-E3).
Please note: When the batteries are changed, the contact between the outdoor transmitters and the base station must be restored – so always restart all devices or start a manual transmitter search (see “Outdoor values reception”).
