Determine Zone Application Rate; Sprinkler Type Default Method (Least Accurate) - Rain Bird ESP-SMT Installation & Operation Manual

!
NOTE: The maximum cycle time is set at 30 minutes
even if the infiltration rate of the soil will allow more
as this assures that additional zones will get irrigated
during the allotted watering time.
As you can see, to optimize an irrigation schedule for each
zone can be a tedious task. The ESP-SMT Control System
automatically optimizes the Irrigation Schedule per the
method described above for each zone on a daily basis.
This is how we can make the claim that the ESP-SMT
"smart" Control System can promote healthier plants with
significant water savings when compared to the traditional
time-based irrigation controllers on the market today.

Determine Zone Application Rate

The Net Application Rate that is entered into the controller
(Default or user-Set) is extremely important to optimize
the irrigation schedule and to prevent water run-off.
The greater the application rate, the shorter the required
run times and/or cycles needed to apply the needed
replacement water to the plants root zone and conversely
the lower the net application rate, the longer the required
run times and/or cycles needed.

Sprinkler Type Default Method (least accurate)

The ESP-SMT controller provides Net Application rates for
the different sprinkler type. To use this method, see page 21,
in the Input Zone Information section.)
The Table below provides the Default Net Application Rate
Values by Sprinkler Type that are used by the controller if
this method is used.
