ENABLE ET: YES
UNITS: INCHES
ET SOURCE: SENSOR
ET ADJUST: 80%
Use the right arrow key to advance to the UNITS: INCHES position.
Use the +/- keys to change the display to METRIC.
Turn the dial to save the setting. For initial setup, turn the dial to
the Controller Type dial position. Millimeters will now be used in the
displays in other dial positions.
Controller Type
Use the +/- keys to enter the number of stations you will be control-
ling with ET. Press and hold either key to accelerate the setting.
At the Controller Type dial position, select the type of Hunter control-
ler to which the ET Module is connected. Use the +/- keys to cycle
through the valid selections: SRC, Pro-C, ICC or ACC.
When the correct controller is displayed, use the Left/Right arrow keys
to advance to the station size.
The ET Module will not allow a number greater than the maximum size
for the selected controller.
NOTE: Enter only the number of stations you wish to control with
ET–they will all run through Program A (except in the ACC controller).
It is possible to allow other stations to run in the controller’s other
programs (B, C, or higher in some models) with traditional programs.
These other programs will always run for the set Run Time in hours:
minutes.
Note that these other programs will not “stack,” and their Start Times
must be set to a safe time, after all ET stations will have completed.
The ET System Start Time will cancel any other programs that may
be running, and will prevent any new programs from beginning, until
the ET watering is complete (except in the ACC controller). The best
practice is to calculate the longest likely run times for the ET adjusted
stations, and add the total to the ET System Start Time. Set the Start
Times for any other programs after this longest possible ET water
window, or set them to complete before the ET Start Time.
Prepare the Controller
The ET System connects to any Hunter SmartPort
®
-equipped irrigation
controller. The controller must be properly prepared to work with ET
prior to use.

Program A will be erased.
ET System will use the controller’s
Program A as a storage area for its ET-based run time informa-
tion. Any information in the controller for Program A will be lost,
after ET System communicates with it. If the Program A informa-
tion was valuable, it is a good idea to write the day/start/run time
information down before connecting ET System.
ET System will not begin to water immediately, and Program A
will not be cleared until ET System decides to water. The system
begins with an initial soil deficit of .1"/2.54mm. This means it as-
sumes the soil is fairly moist, and that plants and soil are in good
condition.
The local ET will then begin to build up, meaning the soil will
become drier. When the moisture level is low enough, ET System
will schedule irrigation and then Program A will be erased. This
may take several days
•
Adjust other Program Start Times.
Programs B, C, and (in ICC
only) D can still be used when ET System is connected, but not at
the same time as the ET station program coming from the ET Sys-
tem. If it is still necessary to use the other programs, adjust their
start times so that they will never overlap the longest program that
ET System is likely to create. When ET starts running stations, it
will automatically cancel all other programs (including D in the
ICC) that may be running at that time, and will prevent any other
programs from starting.
