## Description

The Gardena SPRINKLERSYSTEM Control Unit is a wireless irrigation controller designed to operate 9V Gardena irrigation valves for automated garden watering systems. This battery-powered control unit enables programmable irrigation scheduling without the need for mains electrical connections, making it ideal for remote garden areas, allotments, and locations where power supply is unavailable or impractical. The control unit works in conjunction with the Gardena Programming Unit (Art. No. 1241-20), which allows you to set irrigation schedules that are then transferred wirelessly to the valve-mounted controller at the press of a button. Operating on a single 9V alkaline battery (not included), the unit provides approximately one year of reliable service. The system offers flexibility through optional integration with Gardena rain or soil moisture sensors, enabling water-efficient operation that responds to actual ground conditions. Manual override functionality allows immediate irrigation activation when required, whilst the cable-free design eliminates installation complexity and eliminates the constraints of wired systems. This makes the control unit particularly suitable for landscape contractors, groundskeepers, and professional gardeners managing irrigation systems across multiple zones or sites where flexible, autonomous watering control is essential.
