Simple and Flexible Programming: This irrigation controller offers a wide range of run times and intervals. Vatering time ranges from 1 second to 300 minutes, and watering intervals range from 1 hour to 15 days. This makes your watering schedule fully customizable. Large Multifunctional Display: The oversized 3-inch HD screen allows you to see all data at a glance. Plus, you can save energy as the screen automatically goes to standby after 30 seconds of inactivity. Two AA batteries power the timer for at least 6 months. Multifunction: Manual mode allows for instant watering without interrupting the current irrigation procedure. Rain mode suspends your program for a specified period to avoid overwatering and unnecessary water waste. Child safety mode protects the nozzle timer from being operated by children. Waterproof and Durable: IP65 waterproof rating, tested with 10 kg of water pressure. The top connector is made of reinforced nylon fiber, which is much more durable than ABS or plastic. Intelligent Power System: Smart remaining power display shows how much energy is available. The chip can detect low power and stop the hose timer before the battery dies. Size: 21*12.5*6.3cm.
