## Summary description

The Gardena 1889-20 is an irrigation system part designed for efficient water distribution. It features a maximum water pressure of 12 bar and is compatible with hose diameters of 26.5-33.3 mm, making it suitable for various gardening needs.

## Long description

The GARDENA Water Control Bluetooth is a weatherproof outdoor tap-mounted irrigation controller that lets you configure and operate an automatic garden watering system from your smartphone or tablet. The device connects via Bluetooth within a range of up to 10 metres and is compatible with iOS and Android devices. After simple installation on the outdoor water tap, the free GARDENA Bluetooth App guides you through setup and lets you create up to three individual watering schedules or use the Scheduling Assistant to suggest suitable cycles. A rain break and seasonal watering duration can be set to avoid unnecessary watering. The unit is battery powered (9 V alkaline, not included) and includes a Safe Stop function that prevents the next watering cycle from starting if battery power is low. Three status LEDs indicate Bluetooth connection, watering activity and battery status. The GARDENA Soil Moisture Sensor (sold separately) can be connected to enable moisture-dependent irrigation.
Advantages
The Water Control Bluetooth provides convenient remote programming and manual control via the GARDENA Bluetooth App and a central device button, allowing both scheduled and immediate watering. Its weatherproof design and tap-mounted installation make it suitable for outdoor use, while the scheduling features, rain break and Soil Moisture Sensor compatibility help save water. Battery operation offers flexible placement without wiring, with an estimated battery life of about one year under normal use.
Suitable for
Automatic garden irrigation controlled from a smartphone or tablet
Small to medium gardens and patios where a single tap supplies an irrigation system
Situations requiring scheduled watering with up to three individual schedules
Users who want to add a soil moisture sensor for moisture-dependent watering

Usage recommendations
Use a fresh 9 V alkaline battery for reliable operation and replace it approximately once a year.
