N338 Rain Sensor Irrigation Timer – Energy-Saving Digital Watering System with 8 Customizable Programs, Permanent Memory, and Eco-Friendly DesignItem NO.: SPY-338

🌱 Energy-Efficient Design: The N338 Energy-Saving Rain Sensor Timer features an advanced solenoid valve design, operating efficiently within a water pressure range of 1.0-7.8 bar (14 psi - 114 psi). Powered by 2 AAA alkaline batteries (NOT included), it offers a battery life of over 6 months. This ensures hassle-free, water-saving irrigation without frequent battery replacements, making it an eco-friendly choice for garden maintenance.

🌱 Two Versatile Irrigation Modes: The N338 timer offers two irrigation modes to cater to various watering requirements:
     - Temporary Watering Mode: Start watering instantly for a customizable duration of 1 to 599 minutes.
     - Programmed Watering Mode: Set up to 8 fully customizable schedules, including start time (0:00-23:59), watering duration (1-599 minutes), and watering frequency (every 1-30 days). The intuitive interface and easy-to-navigate buttons make setting and adjusting watering schedules quick and effortless, enabling precise and efficient garden management.

🌱 Rain Sensor Design: Designed with a rain sensor slot on top, the timer automatically pauses watering when rainwater connects the two metal sensor points. This prevents unnecessary water usage during rainy conditions. Once the sensor points are dry, the timer resumes the preset programs, saving water while ensuring optimal plant care and growth.

🌱 Permanent Memory Function: Equipped with a non-volatile memory function, the N338 timer retains all programmed schedules even during battery changes. This eliminates the need to reconfigure settings, saving time and effort while ensuring your irrigation plans run smoothly and consistently without interruptions.
    
🌱 Wide Application: The N338 timer is perfect for various environments, including home gardens, backyard plants, greenhouses, and more. Whether for flowers, vegetables, or lawns, it meets diverse irrigation needs with ease. With its smart and energy-efficient design, the N338 Energy-Saving Rain Sensor Timer helps you effortlessly manage plant growth and maintain a lush, thriving green space.

⚠ Note:
1. Water Pressure Requirements:
The controller cannot be used with water tanks or non-pressurized water sources. A minimum water pressure of 1 bar (14 psi) is required for the solenoid valve to function properly. Insufficient pressure may result in the valve failing to open or only partially opening.
2. Low Battery Alert:
When the battery is low, the controller will not execute irrigation tasks. Please replace the batteries immediately with new branded alkaline batteries.
3. Automatic Mode Switch:
After manually stopping irrigation, the system will automatically switch back to programmed mode after approximately 10 seconds.
4. Key Operation During Use:
While the controller is running, only the 'OFF' button is functional. All other buttons are disabled to prevent accidental changes.
5. Frost Protection: 
During winter, if the outdoor temperature drops below 0°C (32°F), move the controller indoors to prevent freezing and damage.
