Question 1 : Why does not work?
Answer 1. The water pressure is too low, and the water valve cannot be opened or closed normally;
Answer 2. Foreign objects enter the interior, resulting in the failure to close normally;
Answer 3. Whether the set timing task is accurate;
Answer 4. Turn on the rainy day delay;
Answer 5. The battery is insufficient
Answer 6.Can not powered by rechargeable batteries, the voltage is insufficient
The voltage of the rechargeable battery is generally 1.2V, and 2 cells are only 2.4V. The power supply will be insufficient. When the valve is lower than 2.5V, it will enter the low battery protection, and the automatic program will not run.
