Gardena 1889-20. Product colour: Black Blue Compatible hose diameter: 26.5-33.3 mm Maximum water pressure: 12 bar GARDENA's Bluetooth® irrigation control is a convenient product for individually configurable and automatic watering of the garden. GARDENA Bluetooth® APP makes using a smartphone or tablet (iOS/Android) a practical remote control. The irrigation control is easily connected to a water tap. The weather-resistant irrigation control can be operated in a range of up to 10 m in a relaxed manner via a Bluetooth® connection. Thus, the watering of the garden can be triggered by the sun-lounger and adjust it as needed. Simply download the free GARDENA Bluetooth® APP, which takes you through the connection process step by step. Subsequently, the irrigation wizard can APP suggest the ideal watering cycles for the available plants. Optionally three individual schedules can be set by the user. Each schedule consists of a selected start time and duration and can be repeated on different days of the week. Rainfall can also be set manually. These ensure that the garden is not irrigated unnecessarily after heavy rainfall. Furthermore, the humidity sensor available separately can also be connected. This automatically takes care of the demand-oriented and water-saving irrigation. The Bluetooth® connection, the level of the 9 V alkaline battery and an active watering process are indicated by three status LEDs on the control unit. Here, the watering process can also be started and stopped manually at the push of a button. The Bluetooth® irrigation control can be operated with one battery for one season. The practical GARDENA safe stop function also prevents the start of the next planned irrigation, should the battery power no longer suffice, to stop watering.This text is machine translated.
