Rain Bird’s central control systems calculate evapotranspiration (ET) rates using a field-proven proprietary equation and weather sensor input.

The system automatically downloads daily weather data and calculates ET to determine irrigation times for the entire system or specific areas. It includes an ET override feature, allowing users to set specific programs to ignore ET values when determining run times.

The Rain Bucket feature allows rainfall from one day to carry over to subsequent days for more accurate ET calculations. The system can connect up to five weather stations for precise ET values based on different weather conditions around the golf course. Users can set a maximum rainfall limit for areas prone to high run-off.

Additionally, the system generates detailed weather data reports and offers support in ten different languages, including English, French, German, Italian, Japanese, Korean, Portuguese, Spanish, Swedish, and Chinese.
