    As I mentioned earlier, the X-core you were using is not the sensitive and sophisticated controller the hydra wise is, therefore it doesn't see the overcurrent as such.

    I understand. Thank you both for your help. I'll look into the solenoid with the lower amperage from buckner in order to remedy the issue on the systems that are set up with 2 zone valves and a master and going forward I will design the systems based on this new knowledge.

    I had problem with the Pro HC controler, the first day working awesome.

    The most used in Brazil for agriculture is 3 way solenoid valve, Brand Rafhael, 0.125A, and anothers brands from Israel.

    The second day, the Pro HC started with message alerts of overcurrent, we are using only 1 solenoid valve 3 way for each zone, and one master valve the same (Rafhael).

    1 master valve + 1 solenoid valve = 0.25 A, and than the controller

    With or without master master, the controller dont stop the alerts.

    Does it happen on all the zones?

    Would you be able to send a screenshot of the solenoid load report?

    What is the model # of the solenoid?

    Hi Mate,

    Thanks for your answer. Its happen on all zones, with or without master valve.

    The pics of solenoid and Hydrawise that you asked.

    Sorry about my english, its rusted.

    Ok, the Pro-HC timer will send an overcurrent alert on mA draws over 880 mA. So from the picture of the solenoid load report you've sent, zone#7 is at 920 mA.... which is over 880 mA and the reason why you are getting the overcurrent alert.
    We need to find out why you are drawing so many mA. I emailed Raphael to see if they can provide the mA specifications on the solenoid in the picture. I know you said it's .125 mA but we might as well confirm with the manufacturer.
    In the meantime, try to see if there could be anything else that could be causing the overcurrent. For example...
    • A failing solenoid
    • A nicked wire that is being exposed to wet soil
    • Two stations bridged into one station output and the current draw too high.
