The Smart Dial controller saves water and reduces irrigation runoff by employing an advanced technology to automatically reprogram itself based on daily weather patterns and local Evapotranspiration (ET). Using the ET Everywhere™ Data Service, the Smart Dial controller receives a paging signal with the local ET value from an orbiting satellite each evening. Then, through its internal WeatherTRAK™ scheduling engine, the controller adjusts its irrigation programming to replace the amount of water lost through the previous day’s ET. Plus, with per-station programming, Smart Dial adjusts each zone to apply only the water needed, regardless of whether sprayheads, rotors, stream rotors or drip components are used in the zone. The power of ET Everywhere, combined with the WeatherTRAK scheduling engine, puts the Smart Dial controller on the cutting edge of environmental sensitivity and water savings. This unique technology provides proven savings while maintaining healthy, beautiful landscapes. It’s just one more advancement from Irritrol.
