Control irrigation system operation during freezing temperatures.

Imagine going to bed while the temperature is mild, then having your automatic irrigation system go on as usual while a freeze set in overnight...and you arise to see a landscape frozen over, with ice on adjoining driveways, sidewalks and even roadways a real possibility. In some areas, where temperature swings like this are all too common, the results are not only hazardous to the life of your lawn and plants, it can also be hazardous to those who may walk or drive nearby. With the Hunter Freeze-Clik you can prevent irrigation systems from activating by automatically stopping the flow of water when the outdoor temperature drops to a near freezing level. When the temperature rises above that set point, Freeze-Clik simply resets your system to its regular cycle. Easy to mount, easy to use, Freeze-Clik can also be used in conjunction with other weather sensing devices to guarantee the optimum effectiveness of a landscape irrigation system in virtually all types of weather.
