    Welcome, I have no way to show this in a photo/video but there was flooding tonight. The main protagonist is the "Hunter Node 4-section controller". Tonight for a test, my wife and I turned the system on at 4 to get the system ready. On the CCTV footage it could be seen that all 3 sections shut down, except one, and water was pouring all the time. Does anyone know what the cause is?

    And are you sure it's the controller, or has the solenoid valve failed to close (solenoid valve failure/suspension) ?

    it certainly didn't close, because when I got up and heard the sprinklers running in the house I immediately ran to the electro-valve box, touched the electro-valve and water was flowing, and on the controller it said: 1a CLOSE 2a CLOSE 3a CLOSE 4a CLOSE and check voltage, but it's a factory defect that is there right away and can't be fixed.

    And it now works correctly to open and close the solenoid valve? If so, it looks like the controller gave the 9V supply correctly and it was the solenoid valve that got hung up.
    If you have a meter you can measure it to see if it is giving and cutting off 9V.

    Well I would replace the batteries.

    When I manually open and close it, everything is fine and the voltage from the controller is 9V, but I wonder why the solenoid valve is stuck. If I cannot close the water because the controller does not want to turn off the water and the solenoid valve is still running, is there any way to manually turn it off?

    You would have to feed the same voltage with the same parameters and duration to the solenoid valve as from the controller.
    The solenoid valve is a mechanical component, the most sensitive. I don't think they cost much, I'd try replacing it in the future if it's doing such numbers.

Topic summary

The discussion revolves around a malfunctioning Hunter Node 4-section controller, where one section fails to close, resulting in continuous water flow. Initial troubleshooting suggests the issue may stem from a solenoid valve failure rather than the controller itself. The user confirms that the controller indicates all sections are closed, yet water continues to flow, indicating a potential factory defect. Suggestions include checking the voltage output from the controller, which is confirmed to be 9V, and manually operating the solenoid valve. It is recommended to replace the solenoid valve if it remains stuck, as it is a mechanical component prone to failure.
