COMMISSIONING
To establish a connection with the main unit, please follow the instructions manual that came with the
weather station.
1) Remove the battery compartment cover on the rear side of the wireless sensor.
2) Set the required channel using the CH switch
3) Insert 2 pcs AAA batteries – observe the correct battery polarity
4) After the batteries are inserted, a signal is sent to the main unit. The signal can also be sent manually,
using the TEST button in the battery compartment of the wireless sensor
5) Close the battery compartment.
When the signal is received successfully, the measured values are shown on the display on the selected
channel. Use the °C/°F button to change the temperature unit displayed on the wireless sensor.
If the wireless sensor signal is lost, hold down the CH button on the main unit for 3 seconds. The main unit
will re-commence searching for the wireless sensor signal. Now press the TEST button in the battery
compartment of the wireless sensor.
Note: For the wireless sensor, lithium batteries are recommended due to their better resistance to frost. Do
not use rechargeable batteries.
Using multiple wireless sensors
If you want to use multiple wireless sensors, select a different channel for each wireless sensor.
Then proceed same as when establishing a connection with one wireless sensor.
The connection establishment process must be repeated after each battery replacement.
Placement
Placement of the 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. The signal range may be affected by obstacles (walls, trees) and other electrical devices (TVs,
monitors, etc.). You may suspend the wireless sensor from the mounting hole or stand it.
