5. Operating Instructions
5.1 Automatic Watering Modes
The system supports two primary automatic watering modes: Single Watering and Circular Watering. You can configure these through the mobile application.
- Single Watering Mode: Set a specific start time, water duration (from 1 second to 59 minutes and 59 seconds), and frequency (e.g., specific days of the week).
- Circular Watering Mode: Ideal for repetitive cycles. Define the start time, duration, and the interval between watering cycles.
