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. A beep sounds
and the temperature readings from the wireless sensor are displayed on the main unit display.
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 next to the
channel number a small arrow wheel appears. 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 and holding button
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. There is a
mounting hole for suspension on the rear of the main unit. You may also put the main unit on a flat surface
using the folding support. 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 batteries are inserted or the AC adaptor is plugged 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 buttons
and
will function. 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 reception is unsuccessful, reception will be attempted again in another hour, five
