Watering Index 
Click  on the “Watering Index” tab.    Normally, your watering need  will  automatically be calculated 
and  adjusted  based  on  the weather  in  your  area.   However,  if  your computer  is  not  on for  more 
than  24  hours  or  you  do  not  have  Internet  connectivity,  Cyber-Rain  controllers  will  default  to  a 
seasonal watering index.  
The  Watering  Index  displays  the  watering  reductions  based  on  the  historic  seasonal  watering 
pattern.  Cyber-Rain ships with a Southern California index as default (the green line on the chart 
below). You can customize this for your area. 
Remember that  you  originally set  your watering  schedule for  the  hottest months of the  year.   In 
Southern California these are July and August, which is why the green line of the watering index is 
at 100% in the chart below.  During the month of January in Southern California, landscapes have 
historically  needed  only  30%  of  the  water  used  during  the  summer  so  the  default  for  January  is 
30%  (as  indicated  by  the  green line.)    This means that if  you  have set your  schedule to water a 
zone for 10 minutes and your PC is offline in January, your controller will only water that zone for 3 
minutes. 
If you would like to customize your index for your area, first select the month (at the top), and 
then use the slider on the right to set the default water reduction for that month.
