substitute for a well-designed and well-maintained high efficiency
irrigation system.
View Sensor Data
The individual sensor readings can be seen at any time.
Turn the dial to the ET Setup position.
Press and hold the STA button for approximately 5 seconds. The sen-
sor display will appear, in place of the ET Adjust setting.
S = Solar Radiation, hourly average in watts per m

.
T = Temperature, near top of last hour.
H = Humidity (%) near top of last hour.
W = Wind: shows automatic wind factor setting, or (when optional ET
Wind is installed), hourly average.
R24 = Rain (last 24 hours, max). Shows recent rainfall as number of
“tips” of the rain measuring device.
The display is not in inches or
millimeters, but the number of times the tipping-bucket style rain
gauge has tipped.

The module converts the tips to total inches internally, but the display
is the raw data from the sensor. It shows only the number of tips in
the last 24 hours, OR since the last Start Time (watering event).
1 tip of the gauge = .017” or .4318mm precipitation.
Multiply the number of tips shown under R24 by the conversion factor
to obtain approximate rainfall in inches or metric.
The rain display is reset to 0000 at each start time, although the
total is tracked internally.
ET System will automatically adjust for all natural rainfall. How-
ever, if it begins raining before the start time, and more rain occurs
after the start time, the R24 display will only show the rain which
has occurred after the start.
Reset
The recessed Reset button can be used to restore system operation in
two different ways.
Restart:
In rare circumstances, the ET Module’s microprocessor may
become confused, and the display may “lock up”. If this, or other
unusual phenomena, occurs (buttons not responding, odd symbols
in the display), press the Reset button for about one second with a
ballpoint pen tip, and release. This will restart the microprocessor.
The display will momentarily show the welcome screen, then return to
normal operations.
Restart should not erase any of the station, plant, soil, or other
program data.
Full System Reset/Erase:
It is also possible to completely erase the
ET Module memory, to allow complete reprogramming.
This procedure will cause all station, plant, soil, and other program
data to be erased!
The ET System will return to factory default set-
tings, as it came out of the box.
Hold down the + and – keys at the same time, and depress the Reset
button with a ballpoint pen tip for about 1 second. Continue to hold
the + and – keys for approximately one second after depressing the
Reset button, and release.
The display will show “ET SYSTEM ERASING…”. The Reset process
may take up to 5 seconds. When the erase is complete, the display
will show the welcome screen for a few seconds, and then the screen
for the current dial position. All user-programmed information will be
erased.
The ET Module must now be completely reprogrammed, beginning
with the first steps in this manual.
ET Reset (Deficit Clear)
It is possible to clear the watering deficit that has accrued in the ET
