Weather sensors are a necessity on any irrigation system. With the Solar Sync ET, you have a sensor that is an advanced weather sensor which calculates evapotranspiration (ET) and adjusts Hunter controllers daily based on local weather conditions. It is smart irrigation control made simple! The way that Solar Sync works is by measuring the sunlight and the temperature along with ET to determine the correct seasonal adjustment percentage value to send to the controller. Once these are determined, the controller uses the programmed run time and adjusts it to the Solar Sync’s seasonal value to accurately modify the irrigation run time for that day. Not only does it have all those great features, but Solar Sync ET also integrates Hunter’s Rain Clik and Freeze-Clik sensors. What this does is provide a quick response for shutting down your irrigation system during ice, rain, and snow. Hunter Solar Sync is great for residences, businesses, and municipalities alike. The WSSEN system is for use with ACC and X-Core controllers. It includes the Wireless Sync Sensor and a wireless receiver. For more information, contact the pros at PoguePoolSpa.com.
