3. Battery 
voltage 
permanently 
low 
Check battery! 
1.  If the battery voltage remains low, although the solar panel is 
charging, check battery, charge battery or exchange it. 
Check 
battery/charge or 
exchange. 
4. Charging 
error due to 
solar panel 
Check solar panel! 
      Notes ! 
  The normal charging function of the solar panel works as follows: 
when the battery voltage is 14,0 V or more the charging function 
switches off. On the display of the first menu window the sign „OFF“ 
appears when „charging with solar panel“ (1x MENU key)  
  If the battery voltage is 13,9 V or less, the charging function switches 
on and on the display appears „ON“ in the same menu window. 
  If the solar panel does not charge the battery although the voltage is 
13,9 V or less, on the display „OFF“, the reasons are as follows: 
1.  There is not enough light and charging is not possible.  
2.  The „ + / - “ phases of the solar panel are reversed. The polarity 
should be measured.  
3.  The solar panel is defective. Determination by measurement at the 
exit of the panel. 
 
 
 
 
 
 
 
 
 
 
 
 
 
Correct polarity  
 
Change panel  
5. Unreadable 
notifications 
on the 
display 
System voltage / start-up error 
1.  Low voltage may be the reason for unreadable notifications on the 
display . 
2.  This can also happen after first putting the device into operation or 
after connecting the battery again (even if sufficient voltage is 
available) 
 Note ! 
Disconnect battery and solar panel, connect „+/-„of the  ECOSTAR 
cables  (neutralize), after approx.  1 min. connect battery and solar panel 
again. Pay attention to the polarity of the cables!

No length 
specification
on the 
display 
Shut-off sensor / loose PE-pipe windings 
1.  The PE-Rohr is completely pulled off, but the display shows 000 m. 
Notes ! 
a)  In this case the shut-off frame on the RAINSTAR, or rather the shut-
off sensor was activated and the pipe length display switches to 000 
m and the ECOSTAR stops the operation of the RAINSTAR.  
The shut-off frame could also have been activated manually due to a 
loose PE-pipe- winding. 
 
 
 
Set PE Pipe-
Length on the 
ECOSTAR again 
 
 
 
b)  The shut-off frame, or rather the shut-off sensor could also have 
been activated while pulling down the PE-pipe. In this case the length 
of the laid down pipe is shown, the shown value, however, is smaller 
than the actual length of the pulled off pipe. The value must be 
entered again as described below.  
c)  If the length is not counted when pulling off the pipe the value cannot 
be corrected and the  RAINSTAR does not start. In this case the 
shut-off sensor is not adjusted correctly (distance too short, see 
operating manual) 
PE-pipe length specification at the ECOSTAR 
Proceed as follows (see also operating manual) 
a)  Set retraction speed to 11,1 m/h 
b)  Press the key PROGRAM 3x, this way parameter sheet no.1 shows, 
by pressing the key PROGRAM again you get to constant 7.
