If the weather station screen shows the low battery icon
in field no. 9, replace the batteries
in the sensor.
If the weather station screen shows the low battery icon
in field no. 21, replace the batteries
in the station.
Note: It may take up to 30 minutes since the insertion of batteries into the units before the station
begins correctly displaying all measured data and loads DCF time.
Weather Station RESET
If the weather station displays incorrect data or does not respond to button presses, use a thin tool
(e.g. a pencil, paper clip) to press the RESET button on the back of the weather station. This will erase
all data; you will need to set the weather station again.
Changing Sensor Channel and Connecting Additional Sensors
The station can be paired with up to 3 wireless sensors.
1. Long-press the CH button on the station; the icon will start flashing.
2. Remove the battery cover on the back of the sensor and insert alkaline batteries (2× 1.5 V AAA).
3. Set the sensor channel number (1, 2, 3) of your choice by repeatedly pressing the CH button.
The channel number will be displayed on the sensor‘s screen next to the humidity value. Data
from the sensor will be loaded into the station within 3 minutes. Repeat the whole process if
the sensor‘s signal is not detected.
Choose the sensor channel number (1, 2, or 3) by repeatedly pressing the CH button.
The number will be displayed on the station‘s screen in field no. 13.
Setting the Station to Display Data from Multiple Sensors
Press the CH button on the weather station repeatedly to view data from each connected sensor
one by one.
Radio-Controlled Clock (DCF77)
After registering the wireless sensor, the weather station will automatically search for DCF77 signal
(hereinafter referred to as DCF) for 7 minutes; the icon will flash depending on the strength of
DCF signal.
During the search, no other data on the screen will be updated and buttons will be disabled (except
SNOOZE/LIGHT).
Pressing and holding the AM/PM button for 3 seconds cancels the search for DCF signal.
Signal detected – the icon stops flashing and the current time and date will be displayed with the
icon.
Signal not detected – the DCF icon will not be displayed.
To repeat the search for DCF signal for 7 minutes, press and hold the AM/PM button for 3 seconds.
To cancel the search for DCF signal, press and hold the AM/PM button again for 3 seconds.
DCF signal will be synchronised regularly every day between 01:00 and 05:00.
During summer time, the
icon will be displayed below the time value.
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:
1. Move the weather station to another location and try to detect the DCF signal again.
2. Check the distance of the device from sources of interference (computer monitors or television
sets). It should be at least 1.5 to 2 m during the reception of signal.
3. When receiving DCF signal, do not place the weather station in the proximity of metal doors, win-
dow frames and other metal structures or objects (washing machines, dryers, refrigerators etc.).
4. DCF signal reception is weaker in reinforced concrete structures (cellars, high-rise buildings etc.),
depending on the conditions. In extreme cases, place the weather station close to a window in
the direction of a transmitter.
The reception of DCF 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).
