5.3.1.2 Cycle and Soak Programming
A Cycle and Soak program can be used to eliminate water runoff. Runoff occurs whenever the
precipitation rate of the irrigation system exceeds the percolation rate of the soil. The Cycle and
Soak feature allows each individual station to be programmed to eliminate the wasteful effect of
water runoff, thereby maximizing water savings. In a conventional program each station in the
program will water for the full runtime and then the next station will run, this will repeat for the
entire program.
To configure a program for Cycle and Soak operations, refer to the SETUP section on
Cycle and Soak programming.
In a Cycle and Soak program, in addition to the runtime, there are two additional times associated
with each station; the maximum watering time and the soak time. The maximum watering time is
the maximum time that the station will be on before runoff starts to occur.
The soak time is the amount of time that the station must be off before it starts watering again.
The soak time allows the water to percolate into the root zone of the plant material.
In a Cycle and Soak program the Rain Master Eagle Controller calculates a profile to run the
stations that minimizes the total watering time for the program and intelligently schedules stations
to run while other stations are satisfying their soak times. At the end of the profile each station
will have run for its full runtime but the runtime may not be contiguous. Based on the calculated
profile, there may be times that no stations will be on.
