2 outlets for separate automatic watering: 2 zone outputs make it easy to program separate watering for different zones. It has two watering modes: automatic/manual. In automatic mode, the watering duration is between 1 and 99 minutes and the watering frequency between 1 and 23 hours or 1 and 15 days. In manual mode, watering duration is between 1 second and 99 minutes, allowing temporary watering without interrupting the preset watering schedule. ADVANCED CIRCUIT BOARD TECHNOLOGY: The water timer features a high-precision IC and fully closed low-pressure solenoid valve, allowing it to quickly manage complex watering schedules with more stable on/off valve control. It is powered by 2 x 1.5V AA batteries (not included) and can be used for more than 6 months. EASY TO SET AND READ: The large 3.5 x 6.5 cm LCD screen makes it easy to check the next watering time, current time and battery status. Set the current time, start time, duration and frequency with just the press of a button. Your watering system will then automatically follow the schedule. Multifunctional: Rain delay mode delays your schedule until the next watering cycle to prevent overwatering. Child lock mode helps prevent accidental turning on or off of your sprinkler system.
