Works with most Hunter Controllers (SRC, Pro-C, ICC, ACC)
Calculates Evapotranspiration (ET) for your local microclimate
Automatically creates a scientific program and downloads it to your standard controller
Saves water and money
Minimizes water waste, applies just the water your plants need
WiltGard™ technology
Enables it to trigger protective watering when extreme conditions threaten your plants
True station-specific database determines appropriate watering
ET information combines with each zone’s particular plant, soil, sun, and sprinkler data
Easily upgrades most Hunter controllers to weather–based control
No high voltage AC wiring required
Non-volatile memory
Retains your program and site information in event of a power failure
Weather Data at Your Site
(Not from Somewhere Else)
Hunter's ET System requires
no
subscription fees
, and is not based
on any form of broadcast or other
distant weather data. Your irrigation
schedule is based on actual
conditions in your landscape. The
ET System was designed to exceed
standards developed by the Irrigation
Association and government agencies,
using
Smart Water Application
Technology
to minimize waste, while
creating healthier landscapes.
ET System Module
No More Sprinklers Running in the Rain!
Each ET System has a simple user interface, so you
can select from a menu of common sprinkler,
plant, and soil types, or create your own
custom factors. The system’s sensor array
includes solar radiation, relative humidity,
temperature, a rain gauge that tracks
precipitation, plus an optional anemometer
for wind speed. The ET System stops wasteful
irrigation after naturally occurring rainfall, and
automatically resumes sprinkler operation when
conditions return to dry.
ET and Irrigation:
Working with Climate
Plants evaporate moisture through
their leaves, and replenish it through
their roots. In turn, conditions such
as temperature, humidity, and wind
dictate the rate at which the plants
lose their moisture. ET-based irrigation
measures these conditions and
replenishes only the amount of water
lost to plant evaporation. Factors
such as the precipitation rate of your
sprinklers, the crop coefficient of your
plant types, and the infiltration rate
and holding capacity of your soils
are taken into account with simple
menu selections.
Evapotranspiration
and Hunter:
Leading the Way
Evapotranspiration is a formula,
based on weather conditions,
which has been created through
exhaustive research and experimentation
by irrigation professionals.
ET has come to symbolize the
“best practice” for determining
landscape watering needs. Hunter
helped to pioneer this field of automatic
irrigation, and has offered
ET-capable controllers for over 15
years. Now, the ET System brings
this proven technology to a simple,
affordable package that lets all of us
irrigate responsibly.
