Hunter's ET System Continuously Calculates the Ideal Irrigation Schedule for Your Landscape

ON SALE $749.99 + GST (reg. $999.99)
(Installation and set-up included. Offer ends July 31, 2006)


  • Gathers weather data on site, continuously calculates the ideal program for your landscape.

  • Take the guesswork out of irrigation scheduling, by tracking your local microclimate and automatically calculating a scientific irrigation program! The Hunter ET System is an easy-to-add-on accessory (for any Hunter controller that operates with a SmartPort® system) that measures key climatic conditions, and uses them to calculate your local Evapotranspiration (ET) factor. The ET is then downloaded into your irrigation controller to create an irrigation program that is just right for your sprinkler system, plants, and soil conditions. By taking into account the rate at which water is consumed by weather conditions, the ET System will initiate a new schedule to replenish only the water that is actually needed. And our WiltGard™ technology can intervene to trigger protective watering when extreme conditions threaten your plants. The result is a dramatic savings in your water bill (about 30%, on average), healthier root zones, and your participation in conserving our precious natural resources.

    Hunter's new ET System merges proven technology into a simple and affordable package that lets all of us irrigate responsibly.

    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

  • Easy Add-on for any Hunter Controller that Operates with a SmartPort® System

  • Predicting the weather may not be the easiest thing to do these days. But responding to those climate changes by continually calculating the optimum irrigation program for your landscape is now possible with Hunter's new ET System.

    Designed to be easily added to any existing Hunter controller (models SRC, Pro-C, ICC, and ACC, including versions back to 1996), Hunter's ET System continuously measures the local Evapotranspiration (ET) factor. That information is then downloaded to the host controller to create an intelligent irrigation schedule that is just right for your landscape requirements.

    ET-based irrigation is considered a "best practice" by the irrigation industry and most water authorities, and the result can be a dramatic savings—as much as 30 percent—to your water bill. Hunter's ET System conserves water and energy based on actual conditions at the irrigated site, and is not reliant on data from weather stations miles away. Each system has all the sensors necessary for accurate, local ET readings and calculations.


  • Easily Installed

  • The ET System consists of a very small outdoor enclosure mounted near the irrigation controller and a remote weather station mounted no further than 100 feet away. Weighing only 6 pounds, the station is easily mounted on a post, pole, or wall. No external power wiring is needed, since ET gets all of its power from the controller.

  • Key benefits of Hunter's new ET System include:

  • No recurring fees or subscriptions for weather station data.
    Plus, the system's modest initial cost may be offset by rebates from local agencies.
  • On-board database.
    ET System includes plant, soil, and sprinkler information for each zone in the system.
  • WiltGard™ technology.
    Provides protective watering when extreme dry conditions threaten your landscape.
  • "Smart" shutdowns when not needed.
    Suspends irrigation during rain, freezing, or high wind conditions based on its own sensor data.
  • Non-volatile memory.
    Retains your program and site information in the event of a power failure.

  • Hunter's new ET System merges proven technology into a simple and affordable package that lets all of us irrigate responsibly.
