The Hunter ET System gathers weather data on site, continuously self-adjusts to calculate the ideal program for your landscape.
Take the guesswork out of irrigation scheduling, by using your own state-of-the-art weather sensor to track your local microclimate and automatically calculate a scientific irrigation program! The Hunter ET System is an easy-to-add-on accessory (for Hunter SRC, Pro-C and ICC controllers) that measures key climatic conditions, and uses them to calculate your local Evapotranspiration (ET) factor.
ET is the combination of two separate processes whereby water is lost from the soil surface by evaporation and from the plant by transpiration. 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 for your sprinkler system, plants, and soil conditions. 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.

Are there any safety standards my irrigation system must meet?
The main safety concern is regarding the water supply. To avoid contamination of the mains water upstream, in most municipalities, a Dual Check Valve is required at the water connection.
Can I get away with placing my indoor controller outside?
In rare applications, like on a wall under a well covered patio where the space is 100% dry all the time & not exposed to the sun, an indoor controller will continue to operate without issue. But if you’re not sure, we recommend installing an outdoor model. If something does go wrong with your controller due to water damage or the LCD screen failing from sun exposure, the warranty is voided so it’s not worth the risk.
Can I run an irrigation system off a regular garden tap?
A garden tap is an excellent place to connect your irrigation system. Ideally, install a connection point behind the tap (turn the water off first) so you can still use your tap to fill a bucket when you need to.
Can I run my system manually from the controller?
Yes, irrigation controllers typically have a manual function, this will allow you to both operate all zones, or each one individually as you please.
Do I need a plumber to install or fix my system?
No, unless you’re tapping into your water supply, a plumber isn’t required. Most domestic irrigation systems can be installed by anyone half handy.
Do I need a rain sensor?
In some states a rain sensor is mandatory, but regardless it’s something you should include in your irrigation system. Having your system turn on in the middle of a day of rain is not only embarrassing, it’s a terrible waste of water & the overwatering is bad for your garden!

By buying from SunshowerOnline, right here in Australia, you can be sure that your warranty issues are covered, that compatibility & compliance isn't an issue & that you'll be able to get helpful after service advice.
Will an irrigation controller operate all zones at once, or one at a time?
Domestic irrigation controllers will always operate zones one at a time. Even if you try to operate 2 to come on at the same time, the controller will automatically delay the operation of the second zone until after the first zone has finished running.
