COMMISSIONING 

Main unit 

1)  The main unit can be powered by batteries (short-time display backlight for 10 seconds) or  
     by an AC adapter (permanent display backlight possible, 3 brightness levels). 
2)  Remove the battery compartment cover on the rear panel of the main unit by sliding to the right and 
 

insert 3 pcs of AAA batteries (micro). Observe the correct battery polarity. Or connect the power adaptor  

plug into the side socket. The display lights up and all display segments are briefly displayed.  

3)  Replace the battery compartment cover and slide it to the left 

4)  The bars at indoor temperature and relative humidity start flashing, together with the icon  

. 

Searching of the wireless sensor signal will take 3 minutes.

Note:    

observe the correct battery polarity to prevent damage to the weather station. Use  

only high-quality alkaline batteries for the main unit  

                      The battery compartment houses two stands that can be screwed into the holes  
                      on the back of the main unit if the main unit shall not be suspended but stand. 

Wireless sensor 

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 (micro) – 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.
