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 tailored 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. Irrigation 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 desired, it can be activated manually. The large, clear display with user guidance makes programming simple and intuitive. The master channel allows for the connection of the Gardena Pump Control, enabling 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 sheltered outdoor locations, and it has a 230 V mains connection. To ensure reliable and safe operation of the irrigation controller, a power failure backup is possible with a 9 V alkaline battery (battery not included). If desired, a Gardena rain or soil moisture sensor can be connected for water-saving operation.
