8.3 GENERATE THE REFERENCE PROGRAM
Whether you are using the Rain Master Eagle ET feature or not it is important to enter a program
that is representative of the conditions that are being irrigated. The program should take into
consideration several factors including the weather conditions for that time of year for your
location, the precipitation rate, the rainfall, the plant material that is being irrigated, and site
specific information (ie direct sunlight vs shade, etc).
It is important to have a representative program or “reference” program because the controller
will make adjustments to this program over time. If for example, the initially established reference
program results in over watering by 200%, then the Rain Master Eagle will make intelligent
adjustments but optimal water savings will never be achieved.
There are three ways to obtain a reference program for your irrigation controller:
1. If you are familiar with the programming of your irrigated area because you have managed
this operation over time, you may best know what each of your station runtimes and the
frequency of irrigation (water days) that best suits your needs.
2. There are software programs that can be utilized to aid you in determining a reference
program. One internet site to aid in scheduling is www.wateright.org. Select the
“Scheduling” option. The Wateright site was developed by the Center for Irrigation
Technology at California State University, Fresno, California, with significant support from
the United States Bureau of Reclamation. This site prompts you for specific information and
then generates a representative schedule for you.
3. Another option is to seek out an irrigation consultant who has knowledge of water
management and irrigation scheduling. One national organization is the American Society of
Irrigation Consultants. A member list can be obtained at www.asic.org.
Although you can establish a reference program based upon any month of the year, Rain Master
recommends that you pick the hottest time of the season to determine your reference schedule.
Refer to RMIS Part Number 500048, Historical ET Data Tables to determine the hottest month
of the season, the hottest month will have the highest ET value.
Regardless of today’s date, enter your reference program into the Rain Master Eagle controller, as
described in Table 8 - Program Data Entry.

Even though you may have entered the summer reference schedule, once the Rain Master
Eagle has been setup for ET operation, it will always reduce the station runtimes
accordingly to save water regardless of what time of year it happens to be.
Establishing a spring, fall, or winter schedule can be accomplished in a similar fashion
as depicted above.
