Total Mean ET ADD
The RAIN GAUGE is a self-emptying, pping bucket that
can read rainfall in 0.01 inch increments. This informaon
is sent to the controller every hour. The user can set the
controller via the handset to stop irrigaon with from
1/8” and up to 1” of rainfall (3 mm and up to 25 mm).
If the RAIN GAUGE is acve, the following represents the
number of days the scheduled programming will be o.
Wind Speed Setup:
Wind speed seng can be programmed to shut down the
irrigaon system at wind speeds from 8 to 25 miles per
hour (3.5 - 11.1 m/s).
What if:
Rain collector: The weather staon sends informaon
on total rain for the last 24 hours every hour. If rain
exceeds a specic rate, the weather staon will send the
informaon every 10 minutes.
Windy day: The weather staon sends wind speed
informaon every hour. If wind speed exceeds a specic
speed, the weather staon will send the informaon
every 10 minutes.
Technical Informaon
Reseng the controller:
To reset the new controller, use the two yellow and the
yellow with black stripe wires. Match the wires color
polaries with a nine volt-baery.
Touch the two wires at the same me to the baery, the
yellow sensor wire will touch the posive (+) end of the
nine volt-baery, while at the same me the yellow with
black stripe wire will touch the negave end (-) of the nine
volt-baery.
The controller will have 5 minutes aer reset to connect
to 0 instead of 2 minutes.
Maximum me of solenoid operaon in any given day
using the new LEIT-2ET.
Energy stored per super-cap voltage:
Enter V: 7 (3-7)
Joules: 81.6666667
Number of solenoid actuaons: 49
Lightning
In case of lightning struck in close proximity to the
controller and caused a reset, the controller me will be
able to keep track of itself.
Seng Informaon:
* Default setting can be adjusted to specific distribution
uniformity.
NOTE: An audit of the site cannot be performed prior
to inial seng of the LEIT ET System, we recommend
soaking the soil thoroughly to ensure the soil is wet as a
reference point for the system from which the LEIT-2ET
starts calculang the site ET.
FINE-TUNING THE SYSTEM: To compensate for
established landscape species that require relavely
large or small amounts of water, or landscapes which
are dicult to evaluate, we recommend monitoring
both the plant health and the soil moisture level on a
weekly basis. If the plants are showing signs of distress or
the soil appears to be oversaturated, ne-tuning of the
system can be accomplished ulizing the ET Edit feature.
The system can be ne-tuned based on management
determinaon, plant species, weather paern, locaon
and the ET zone seng. Either an upward or downward
adjustment in percent can be made to adjust to the actual
ET seng condions. Again, DIG strongly recommends
a careful monitoring of the site for the rst month of
operaon.
ET Edit Setup:
ET EDIT is used to opmize the ET seng. For example,
the user can adjust ET seng by increasing the ET value
up to 200% or decreasing the ET value to 30%. This
feature is used for each of the two valves.
Rain Gauge Setup:
RAIN GAUGE can be programmed to shut down the
irrigaon system when it is raining.
