Works with virtually any controller! The ET Manager is the most accurate product of its kind, featuring hourly (not just daily) wireless updates from local precision weather stations. ET Manager technology is based on the Irrigation Association endorsed, ASCE*-standardized ET equation, and includes data from all required climatic variables (solar radiation, temperature, wind, and humidity). An optional onsite rain gauge can further localize the weather data accuracy. With the ET Manager, your irrigation system will always be in tune with the weather.
ET Manager Scheduler software, included free, makes it easy to program your ET Manager and existing or new controller. Best of all, you get the benefit of comprehensive weather station data without having to install and maintain one onsite.
