COMMISSIONING
Main unit
The main unit is powered by an AC adaptor. The battery only serves as a backup power supply for keeping
the main unit settings. Use only the delivered AC adaptor.
Backup battery installation
1) Remove the battery compartment cover on the rear side of the main unit by turning it to the left.
2) Insert 1 pc of a CR2032 battery (button), observe the correct polarity.
3) Close the battery compartment by turning the cover to the right.
Connecting the AC adaptor
1) Connect the power adaptor plug into the socket on the side of the main unit.
2) Connect the other side of the AC adaptor to a mains socket.
After the power supply is connected, the display shows all segments for 3 seconds and a beep sounds.
Then, the wireless sensor signal reception icon flashes on the display at the outdoor values
(OUTDOOR REMOTE) channel number for 3 minutes.
Wireless sensor GARNI 030H
1) Remove the battery compartment cover on the rear side of the wireless sensor.
2) Set the required channel using the switch in the battery compartment.
3) Insert 2 pcs AA (mini) batteries – observe the correct polarity.
4) Push the TX button. The temperature readings from the wireless sensor are displayed on the main unit
display.
5) Close the battery compartment.
Once the connection of the main unit to the wireless sensor is established, place the main unit and the
wireless sensor in the desired location within the range of the wireless sensor signal
Using multiple wireless sensors
The main unit allows to connect up to 3 wireless sensors which can be placed at different spots. Each
wireless sensor must be assigned its own channel number (1, 2 and 3).
1) Place the main unit and the wireless sensor next to each other.
2) Remove the battery compartment cover on the side of the wireless sensor.
3) Assign a number to each wireless sensor using the switch so that the numbers are unique.
4) Insert 2 pcs AA (mini) batteries, observe the correct polarity. Then push the TX button. The display
of the main unit will display the temperature reading measured by the wireless sensor on the respective
channel
5) To display the readings from a given wireless sensor, select the desired channel on the main unit
using button .
To automatically change the channel in ascending order, press button repeatedly until a small
arrow wheel appears next to the channel number . The main unit will alternate between displaying
the readings from all wireless sensors.
The reception of the wireless sensor signal can be also started manually by pushing button and
holding it for 3 seconds.

Placement of the weather station
Main unit
Select the location of the main unit away from direct sunlight. Test the connection to the wireless sensor
before final installation. If there is a problem with the signal reception, select another location. You may also
put the main unit on a flat surface. Placement near TVs, monitors, computers, etc. may negatively affect the
reception of the DCF-77 signal and the wireless sensor signal.
Wireless sensor
Place the wireless sensor away from direct sunlight not to compromise the measurement. Placement
outdoors, at the northern wall is recommended. Obstacles such as walls, concrete, metal structures and
large objects reduce the signal range. Position the wireless sensor vertically for optimum signal
transmission. Maximum open space signal range is 60 meters.
The signal range may be affected by obstacles (walls, trees) and other electrical devices (TVs, monitors,
etc.).
Time controlled by the DCF-77 radio signal
The weather station is equipped with the DCF-77 time/date control signal receiver, the signal is
broadcasted by a transmitter from Frankfurt am Main, Germany, with a range of about 1500 km. When
outside this range, the time and date can be adjusted manually. The time and date are adjusted every day.
When the AC adaptor connector is connected to the main unit, the display lights up, all display segments
are briefly displayed, and a beep sounds and the wireless sensor signal reception commences.
After the connection with the wireless sensor has been established, the reception of the DCF-77 is
commenced, indicated by flashing icon . This process may take several minutes. The display will be off
during the reception of the DCF-77 signal and the functionality of the main unit will be limited. Only the
and SNOOZE/LIGHT buttons will function. To terminate the DCF-77 signal reception, press the
button and hold for 3 seconds.
When the signal is received successfully, the display shows the current time, date and signal reception icon.
The icon shows the signal reception strength, the more bars the better the signal. The weather station
will automatically receive the DCF-77 signal for time adjustment every day at 1:00, 2:00 and 3:00. If the
reception is unsuccessful, it will be attempted again in another hour, five times in total. The received time is
compared with the time on the main unit and adjusted if necessary. For better signal reception, place the
main unit near a window.
If the DCF-77 signal is not received (icon is not displayed), reception will be interrupted, and it will be re-
attempted in an hour until the DCF-77 signal is received successfully.
Note:
The received DCF-77 time adjustment signal strength may be affected by the geographical location or the
premises where the weather station is located.
For better reception, the main unit should be placed on a flat non-metallic surface, near a window on the
upper floor of your house away from electrical appliances such as a TV, computer, etc.
Manual reception of the DCF-77 signal
Press and hold button until the icon is displayed and the manual search for the DCF-77
commences. If the reception is unsuccessful, the icon disappears, and the time is not adjusted
automatically. After successful signal reception, the time and date will be adjusted even if they were
manually set before.

Weather forecast
The forecast is based on the change in barometric pressure, generally speaking when the barometric
pressure rises, the weather improves and vice versa. The forecast accuracy is 75% and is valid for the next
12 to 24 hours for the area within a radius of 30 to 50 km.
The weather forecast uses six icons – sunny, somewhat cloudy, cloudy, precipitation, heavy rain and snow.
Sunny Somewhat
cloudy
Cloudy Precipitation Heavy rain Snow
Note: the snow icon replaces the precipitation or heavy rain icons if the outdoor temperature from
the channel 1 sensor is below -4°C. If the channel 1 is not used, it is the temperature from

7
channel 2 sensor, if channel 2 is not used, then it is the temperature from the channel 3
sensor.
Weather trend arrows
The weather station updates the weather trend arrows according to the barometric pressure reading
Barometric pressure increased
Barometric pressure unchanged
B
a
ro
metric pressure decreased
E.g.: the weather forecast indicates rain, the barometric pressure drops abruptly and quickly, therefore the
probability of heavy rain is higher.
Arrows of temperature / relative humidity trends
The main unit displays the trend icons of the measured quantities based on the temperature and relative
humidity readings. If there is no arrow displayed, there is no change.

TROUBLESHOOTING
problem / situation solution
DCF-77 signal not received relocate the main unit; start the manual signal search;
set the time and date manually
instead of temperature and humidity readings temperature readings are outside the measurable range
the display shows: H.HH or LL.L
the weather station is not working correctly reset the factory settings of the main unit by removing
