4. 

Afterwards, the Weather Center will start receiving data from the 
transmitter. The transmission reception icon will be blinking to 
indicate that the station is trying to get the thermo-hygro transmitter 
data. The outdoor temperature, humidity, wind data should then be 
displayed on the Weather Center. If this does not happen after 135 
seconds, the batteries will need to be removed from all units. You will 
have to start again from step 2.  

5. 

The transmitter reception icon is now blinking again to indicate that 
the station is trying to get the rain sensor data. It will stop blinking 
once the rain sensor has been detected. If this does not happen after 
135 seconds, you will need to start again from step 2. 

6. 

You may need to check the cable for correct connection and all the 
components for correct function by manually turning the wind-gauge 
by moving the wind-vane; tilting the rain sensor to hear the impact of 
the internal moving seesaw, etc. (see 

Positioning

 below). 

7. 

Time and date shall be manually set (See 

Manual Setting

 below). 

8. 

After the Weather Center has been checked for correct function with 
regard to the above points and found fit, the initial set up of the 
weather station system is finished and the mounting of the system 
components can take place. It must be ensured however that all 
components work properly together at their chosen mounting or 
standing locations. If e.g. there appear to be problems with the 915 
MHz radio transmission, they can mostly be overcome by slightly 
changing the mounting locations or turning the base station. 

 

Note: 

The radio communication between the receiver and the transmitters in the 
open field reaches distances of max 330 feet, provided there are no 
interfering obstacles such as buildings, trees, vehicles, high voltage lines, 
etc. 

 

9. 

Radio interferences created by PC screens, radios or TV sets can in 
some cases entirely cut off radio communication. Please consider this 
when choosing standing or mounting locations. 

 

Note : 

 

After batteries are installed in the transmitter, install the batteries in 
the weather center to receive the signal from the transmitters as soon 
as possible. If the weather center is powered more than 5 hours after 
the transmitter is powered, the weather center will never receive 
signal successfully from the transmitters. In this case, user will need 
to reinstall the batteries from all the transmitters to redo set-up 
procedure.  

 

 

After batteries are installed, there will be synchronization between 
weather center and the transmitters. At this time, the signal reception 
icon will be blinking. When the signal is successfully received by the 
weather center, the icon will be switched on. (If it is not successful, 
the icon will not be shown in LCD) So the user can easily see 
whether the last reception was successful (icon on) or not (icon off). 
On the other hand, the short blinking of the icon shows that a 
reception is in progress.

If the signal reception is not successful on the first frequency 
(915MHz) for 45 seconds, the frequency is changed to 920MHz and 
the learning is tried another 45 seconds. If still not successful, the 
reception is tried for 45 seconds on 910MHz. This will also be done 
for re-synchronization. 

 

HOW TO INSTALL AND REPLACE THE BATTERIES INTO 
THE THERMO-HYGRO SENSOR 

The outdoor Thermo-hygro sensor works with 2 x 
AA, IEC LR6 1.5V batteries. To install and replace 
the batteries, please follow the steps below: 
1.  Uninstall the rain cover of the transmitter. 
2.  Remove the battery compartment cover. 
3.  Insert the batteries, observing the correct 

polarity (see the marking in the battery 
compartment). 

4.  Replace the battery cover. 

 

 
 

 

Note: 

In the event of changing batteries in any of the units, all units need to be 
reset by following the setting up procedures. This is because a random 
security code is assigned by the thermo-hygro sensor at start-up and this 
code must be received and stored by the Weather Center in the first 
several minutes of power being supplied to it. 

 

HOW TO INSTALL AND REPLACE THE BATTERIES INTO 
THE RAIN SENSOR 

 
 
 
 
 
 
 
 
 
 

The rain sensor works with 2 x AAA, IEC LR3, 1.5V batteries. To install and 
replace the batteries, please follow the steps below: 
1. 

Press tabs back to unlock rain sensor cover. (Figure 1) 

2. 

Lift rain sensor cover to access battery compartment. (Figure 2) 

3. 

Insert the batteries, observing the correct polarity (see the marking in 
the battery compartment). (Figure 3) 

4. 

Replace the battery cover and the rain cover onto the unit. 

 

Note: 

In the event of changing batteries in any of the units, all units need to be 
reset by following the setting up procedures. This is because a random 
security code is assigned by the rain sensor at start-up and this code must 
be received and stored by the Weather Center in the first several minutes 
of power being supplied to it.

HOW TO INSTALL AND REPLACE THE BATTERIES INTO 
THE WEATHER CENTER 

The Weather Center works with 3 x AA, 
IEC LR6, 1.5V batteries. When the 
batteries need to be replaced, the low 
battery symbol will appear on the LCD. 
To install and replace the batteries, 
please follow the steps below: 
1.  Remove the battery compartment 

cover. 

2.  Insert the batteries observing the 

correct polarity (see the marking in 
the battery compartment). 

3.  Replace the battery cover. 

 

 

BATTERY CHANGE: 

It is recommended to replace the batteries in all units every 24 months to 
ensure optimum accuracy of these units. 

 

Please participate in the preservation of the environment. 
Return used batteries to an authorized depot. 

 

 

Note: 

The stored History record will not be kept after the battery change is done 
on the Weather Center.
