How to set the timer:
1. Calculate the water plants need. The water output is 20mL/s.
Example: When watering 4 potted plants in the o?ce, the water demand of each potted ?ower is 80mL each time, then the total water demand of the plants is 4*80=320(mL). The water output of the machine is 20mL/s, so the watering time should be 320/20=16s each time. And the plants should be watered once every 8 days, therefore, the machine should be set to: Days: 8, Time: 16.
2. Press any key to wake up the machine. Press "Days" button to set the days of watering intervals (HH-1-10; "HH" means 12-hours interval for watering twice a day). Press the "Time" button to set the single watering time (0-180s; "H1" means 2 minutes; "H2" means 3 minutes).
3. Watering starts in 3 seconds after setting successfully.
4. Press any key to stop.
