This is the amount of water in the ET gage (measured as a percentage). Whenever the gage is refilled, this
should be reset. Press the
%
key, then the
UP ARROW
key to reset the value (the maximum setting is 99%).
Press the
ENTER
key after the value has been reset.
PROG :
Indicates the program that the current station is assigned to. A station can be assigned to only one program.
Press the
CHANGE
key until the program is highlighted. Press the
UP ARROW
key to select the desired program.
Estimated Mins : The Estimated Minutes is the amount of irrigation time calculated by the controller, it is the maximum amount of
irrigation that will be applied in the current 24 hour period. This setting cannot be changed directly by the user.
The time is calculated by the program based on the precipitation rate for the current station, the amount of ET in
the ET table, crop coefficients (if used), and the % of ET (described below). If any of these values are changed the
Estimated Minutes will change.
Mins Per Cycle : The Minutes Per Cycle is the maximum amount of irrigation time applied in a cycle. This setting should be the
most water you would want the current station to apply at any one time, that is before water starts to “run-off”. If
the setting is less than the Estimated Minutes (described above) there will be multiple cycle starts, until the total
time applied equals the Estimated Minutes. If the setting is more than the Estimated Minutes the run-time will be
equal to the Estimated Minutes (total run-time will never exceed the Estimated Minutes). Press the
CHANGE
key
until the setting is highlighted, Press the
UP ARROW
or
DOWN ARROW
key to adjust the setting.
Soak-in Time :
The Soak-in Time is the amount of time between multiple cycle starts (if there are multiple cycle starts). If there are
no multiple cycle starts, this setting will be ignored by the program. Press the
CHANGE
key until the setting is
highlighted, Press the
UP ARROW
or
DOWN ARROW
key to adjust the setting.
Last Min :
This is the average applied time for the last five irrigation cycles. It is for your information only.
% of ET :
This is the individual station adjustment to daily-ET. This adjustment is used to fine-tune each stations run-time. It
is one of the factors used in calculating the Estimated Minutes (described above). Press the
CHANGE
key to
highlight the % of ET, Press the
UP ARROW
or
DOWN ARROW
key to adjust the setting. As you make adjustments
to this setting, you will see the Estimated Minutes change. Try to make small adjustments, 5% to 10% at a time,
and allow a few days to pass before re-adjusting if necessary. Daily-ET only replaces the moisture that has
evaporated since the last irrigation cycle, if for example you have a problem with a valve, and an area becomes
stressed from lack of water, use the manual water feature to add water until the area is back to normal conditions.
The % of ET setting is used to adjust for factors such as different types of plant material (e.g. turf would generally
have a higher adjustment factor that shrubs), soil conditions (e.g. sandy soils might have a higher adjustment
factor than clay type soils because they don’t hold moisture as long), terrain (e.g. the system at the top of a slope
might have a higher adjustment factor that the system at the toe of a slope). If this adjustment ends up a large
number from 100% (in either direction), you should re-evaluate your precipitation rate numbers for that station,
which were entered in the Set-Up program (described earlier in this guide).
9. 12-Month Schedule
If 12-Month Schedule was enabled (while in the Set-Up program described earlier in this guide), it must be programmed after
leaving set-up. When using the 12-Month Schedule, you will be able to pre-program for each month of the year, every stations
Minutes Per Cycle and Soak-in Time settings, and each programs Start Time and Water Days. To program 12-Month Schedule
starting from the main display, Press the

key, the display will appear as shown below.
