Total Mean ET ADD
The RAIN GAUGE is a self-emptying, pping bucket that
can read rainfall in 0.01 inch increments. This informaon
is sent to the controller every hour. The user can set the
controller via the handset to stop irrigaon with from
1/8” and up to 1” of rainfall (3 mm and up to 25 mm).
If the RAIN GAUGE is acve, the following represents the
number of days the scheduled programming will be o.
Wind Speed Setup:
Wind speed seng can be programmed to shut down the
irrigaon system at wind speeds from 8 to 25 miles per
hour (3.5 - 11.1 m/s).
What if:
Rain collector: The weather staon sends informaon
on total rain for the last 24 hours every hour. If rain
exceeds a specic rate, the weather staon will send the
informaon every 10 minutes.
Windy day: The weather staon sends wind speed
informaon every hour. If wind speed exceeds a specic
speed, the weather staon will send the informaon
every 10 minutes.
Technical Informaon
Reseng the controller:
To reset the new controller, use the two yellow and the
yellow with black stripe wires. Match the wires color
polaries with a nine volt-baery.
Touch the two wires at the same me to the baery, the
yellow sensor wire will touch the posive (+) end of the
nine volt-baery, while at the same me the yellow with
black stripe wire will touch the negave end (-) of the nine
volt-baery.
The controller will have 5 minutes aer reset to connect
to 0 instead of 2 minutes.
Maximum me of solenoid operaon 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 actuaons: 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.
Seng Informaon:
* Default setting can be adjusted to specific distribution
uniformity.
NOTE: An audit of the site cannot be performed prior
to inial seng 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 calculang the site ET.
FINE-TUNING THE SYSTEM: To compensate for
established landscape species that require relavely
large or small amounts of water, or landscapes which
are dicult 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 ulizing the ET Edit feature.
The system can be ne-tuned based on management
determinaon, plant species, weather paern, locaon
and the ET zone seng. Either an upward or downward
adjustment in percent can be made to adjust to the actual
ET seng condions. Again, DIG strongly recommends
a careful monitoring of the site for the rst month of
operaon.
ET Edit Setup:
ET EDIT is used to opmize the ET seng. For example,
the user can adjust ET seng 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
irrigaon system when it is raining.
