Getting Started

Plug the power adapter into the station, then insert batteries first into the weather station (3× 1.5 V AA), then into the outdoor sensor (2× 1.5 V AA). When inserting the batteries, make sure the polarity is correct to avoid damaging the weather station or sensor. Only use 1.5 V alkaline batteries of the same type; do not use rechargeable 1.2 V batteries. The lower voltage may cause both of the units to not function.
Place the two units next to each other. The weather station will detect the sensor signal within 3 minutes. If signal from the sensor is not detected, long press the CH button on the weather station to repeat the search.
If the outdoor temperature reading disappears from the screen, long press the CH button on the weather station. The weather station will reset all values and repeat the search for sensor signal.
We recommend placing the sensor on the north side of the house. The range of the sensor may decrease substantially in areas with a large number of obstacles.
The sensor is resistant to dripping water; however, it should not be continuously exposed to rain.
Do not place the sensor onto metal objects; doing so will reduce the transmission range.
If the low battery icon is displayed, replace batteries in the sensor or the weather station.

Switching Channels and Connecting Additional Sensors

Select channel – 1, 2 or 3 – for the sensor by repeatedly pressing the CH button. Then, long-press the CH button. The icon will start flashing.
Remove the battery compartment cover on the back of the sensor and insert batteries (2× 1.5 V AA).
Set the chosen sensor channel number (1, 2, 3) by sliding the CH button located in the battery compartment of the sensor. Data from the sensor will be loaded within 3 minutes.
If sensor signal is not detected, remove the batteries and reinsert them.

Displaying Data from Multiple Sensors, Automatic Cycling through Values

from

Connected Sensors
Press the CH button repeatedly to display data from all connected sensors one by one. You can also activate automatic cycling through data from all connected sensors:

Turning on cycling
Repeatedly press the CH button until the icon appears on the screen.
Data from all connected sensors will be shown automatically and repeatedly one after another.
Turning off cycling
Repeatedly press the CH button until the icon disappears.
Note: automatic cycling can only be activated if 2 or 3 sensors are paired with the station.

Radio-Controlled Clock (DCF77)

After being registered by the wireless sensor, the weather station will automatically start searching for DCF77 signal (DCF for short) for 7 minutes; the icon flashes. During the search, no other items on the screen will be updated and the buttons will be disabled (except SNOOZE/LIGHT). Once the signal is detected, the icon will stop flashing stays on the screen) and current time will be displayed. During daylight saving time, DST appears on the screen. If no signal is detected, the DCF icon will not be shown. The weather station will then automatically repeat the search for DCF signal every 3 hours. To manually repeat the search for DCF signal, long-press the RCC button. To cancel the search, shortpress the RCC button. DCF signal will be synchronised daily between 1:00 and 5:00.

Note: If the weather station detects DCF signal but the current time on the screen is incorrect (e.g. shifted ±1 hour), you must set the correct time zone for the country where you are using the station, see Manual Settings.
In standard conditions (at safe distance from sources of interference, such as TV sets or computer monitors), the reception of time signal takes several minutes. If the weather station does not detect the signal, follow these steps:

Move the weather station to another location and try to detect the DCF signal again.
Check the distance of the clock from sources of interference (computer monitors or television sets). The distance should be at least 1.5 to 2 m during the reception of signal.
When receiving DCF signal, do not place the weather station near metal doors, window frames and other metal structures or objects (washing machines, dryers, refrigerators, etc.).
In reinforced concrete structures (cellars, high-rise buildings, etc.), the reception of DCF signal is weaker, depending on the conditions. In extreme cases, place the weather station close to a window in the direction of a transmitter.

Reception of DCF77 radio signal is affected by the following factors:

thick walls and insulation, basements and cellars;
inadequate local geographical conditions (these are difficult to assess in advance);
atmospheric disturbances, thunderstorms, electrical appliances with no interference elimination, television sets and computers located near the DCF receiver.

Manual Settings

Long-press the SET button.
Then, repeatedly press the SET button to choose settings for: calendar language – button beeping on/off (BP ON/FF) – DCF signal reception on/off (RCC ON/ OFF) – time zone (ZOE) – year – date format – month – day – 12/24h time format – hours – minutes – °C/°F unit of temperature – unit of pressure.
Navigate between the values by pressing SET, adjust settings using the up and down arrows
Calendar language abbreviations are as follows: GER – ENG – ITA – FRE – DUT – SPA – DAN.

Atmospheric Pressure – History

The station displays atmospheric pressure and a chart of pressure readings in the last 12 hours in field no. 19.
The chart of pressure history is animated (cannot be changed).
Moving the weather station to another place will affect the measured values.
Measurement will stabilise within 12 hours of battery insertion or relocation of the weather station.

Displaying Maximum and Minimum Temperature and Humidity Readings

Press the MEM button repeatedly to gradually display the maximum and minimum readings of temperature and humidity.
Holding the MEM button while viewing MAX/MIN values will erase the memory.
The memory of measured values is automatically erased every day at 00:00.

Setting an Alarm
Long-press the button; ALM will appear on the screen and the alarm time setting will start flashing.
Set the time by repeatedly pressing the buttons; confirm and navigate in the menu by pressing Press the button again to activate the alarm.
Alarm active – icon displayed.
Alarm deactivated – icon not displayed.

Snooze Function
The ringing of the alarm can be postponed by 5 minutes using the SNOOZE/LIGHT button located on the top part of the weather station.
Press the button when the alarm starts ringing. The icon will be flashing.
To cancel the SNOOZE function, press any other button – the icon will not be displayed.
The alarm will trigger again the next day.
If you do not press any button while the alarm is ringing, the ringing will stop automatically after 2 minutes.

Station Screen Illumination

When powered via adapter
Permanent screen illumination is set by default.
Repeatedly pressing the SNOOZE/LIGHT button allows you to set 3 illumination modes (100 %, 50 %, off).

When powered only by 3× 1.5 V AA batteries:
Screen illumination is off. Pressing the SNOOZE/LIGHT button will turn screen illumination on for 10 seconds, then it turns off again. When the station is only powered by batteries, permanent screen illumination cannot be activated!
Note: The inserted batteries serve as backup for the measured/set data.
If batteries are not inserted and you unplug the adapter, all data will be erased.

Automatic Dimming of Screen Illumination

When the station is powered from the adapter, you can programme automatic dimming of screen illumination from 100 % to 50 %.
Long-press the SNOOZE/LIGHT button; the function icon will start flashing.
Repeatedly pressing the button activates (ON) or deactivates (OFF) the function.
Confirm the setting by pressing SNOOZE/LIGHT; the time setting will start flashing (1 hour resolution).
Press the button repeatedly to set the hour when you want the dimming to activate, confirm by pressing SNOOZE/LIGHT.
Press the button repeatedly to set the hour when you want the dimming to deactivate, confirm by pressing SNOOZE/LIGHT.
The screen illumination will dim at the set time.

Note:
Once you have set activation (ON)/deactivation (OFF), the setting will save automatically after 20 seconds unless you press another button. By default, the screen is set to dim from 22:00 until 8:00. If you press the SNOOZE/LIGHT button during the set time, screen brightness will return to 50 % after 10 seconds.

Weather Forecast

The station uses changes in atmospheric pressure to forecast weather for the next 12–24 hours for an area within the radius of 15–20 km. The accuracy of weather forecast is 70–75 %. The forecast icon is displayed in field no. 3. As the weather forecast may not be 100 % accurate, neither the manufacturer nor the seller can be held responsible for any loss caused by an incorrect forecast. When you first set or reset the weather station, it takes approximately 12 hours before the weather station begins forecasting correctly.

The snowflake icon will be flashing at outdoor temperature between 0 °C and +2.9 °C.
The snowflake icon will remain on the screen at outdoor temperature below 0 °C.

Comfort Level Indicator – Smiley

The comfort level indicator is displayed in field no. 9.

If indoor humidity is between 40–70 % RH, the screen will display the icon.
If indoor humidity is lower than 40 % RH, the screen will display the icon.
If indoor humidity is higher than 70 % RH, the screen will display the icon.

Setting Temperature Limits for Maximum and Minimum Temperature

Temperature limits can be set independently for up to 3 outdoor temperature sensors.
Press the CH button repeatedly to select the number of the sensor you want to set the temperature limit for.
Long-press the ALERT button. The value for setting a maximum temperature alert will start flashing.
