The Classic Irrigation Controller 4030 is particularly used when the water supply is insufficient to operate the entire system – consisting of multiple irrigation systems – simultaneously. It also regulates the individual irrigation intervals for each zone, accommodating varying water needs of different plant areas, thus ensuring customized and optimal watering. The Classic Irrigation Controller 4030 is designed to connect up to four 24 V irrigation valves. For versatile irrigation programming, up to three programs can be stored per valve. The watering days and cycles can be individually selected, and the watering duration can be set between one minute and 3 hours 59 minutes, with a central adjustment option from 0 to 200%. If immediate watering is required, it can be manually activated. The large, clear display with user guidance makes programming simple and intuitive. The Gardena Pump Control can be connected via the master channel, allowing a pump to be used as an alternative water source. The Gardena Classic Irrigation Controller 4030 can be used both indoors, such as in a garage, and in rain-protected outdoor areas, and it has a 230 V mains connection. To ensure reliable and safe operation of the irrigation controller, a power failure backup using a 9 V alkaline battery is possible (battery not included). If desired, a Gardena rain or soil moisture sensor can be connected for water-saving operation.
