Thank you for your response. Perhaps I wasn't clear enough on my question. I performed all the tests that you have suggested and the fact that the controller and the valves were all getting proper voltage but not working was a mystery. I would see on the controller that each zone would pop up but no water was coming out. So here is what I did that solved the problem. Even though I had flipped the rain sensor to bypass at the controller the system was detecting rain or moisture. The next step was to actually pop off the top of the rain sensor and physically disable it, not just bypass it. That did the trick and all zones came on with water pouring out with no problem. Come to find out that due to the high humidity there was some moisture in the rain sensor which was preventing the proper operation. Thanks for your help and I hope my solution is useful to others.

Thanks so much! I found that all the stations where having an issue and returned the whole unit and got another one. Works like a charm! Thanks so much for your fast reply!!

Am also having the same any help?

I have the very same problem, drives me crazy. Seems as if the whole controller must be hard reset to get rid of this -- and manual has nothing to say about this code.

I have the same issue with my EC-600. Is there any solution?

If your Pro-C has a slidebar indicating Power On (locked) Power Off (unlock) you can use the main module for the version 3 PC-300. The part number is 466500. If your backpanel has clips to connect the modules you will have to replace the whole controller because the backpanel for that controller is not compatible with version 3 modules.

Please contact Hunter Technical Services for help with your problem. By email support@hunterindustries.com, or phone 1800-733-2823. If you call by phone please be in front of the controller with a multimeter so we can walk you through some diagnostics. We are available MON-FRI 6am to 4pm PST.

Make sure the ribbon cable is securely in the face pack. I had a similar problem where mine was going nuts and I accidentally pushed the ribbon cable in securely and everything went back to normal.

Normal status should show the time and date. If it doesn't try moving the dial to another dial setting and back to Run. If that does not fix it try performing a factory default.

Hunter Irrigation thank you very much

Thank you for your timely reply. One thing I did not mention is that I also have a solar synch attached to the Pro-C controller. The solar synch display is blank and I've tried taking the battery out, disconnecting its power leads, and pressing the 3 buttons but I've had no luck getting a display. I did not mention this in my first post as it didn't seem relevant to the situation based on the ERR documentation indicating something with the smartport only. I went ahead and disconnected the smartport wires first from the terminals and the Pro C display still pulsed Err. With the smartport wires still disconnected I then unhooked the solar synch's blue wire from the REM terminal - the display stopped showing the pulsing ERR. Does this mean the solar synch module is causing the issue? Just to clarify this is a professional installation from 2013 that I've had no issues with until today. The only individuals that access the box inside the garage are myself and the sprinkler service I use - they gave no indication of this problem when doing startup maintenance on it in mid May. I didn't notice the pulsing ERR and blank display on the solar synch until I attempted using it in June as we've received sufficient rain during that interval. The first solar synch originally installed did fail after 1 year and the sprinkler install company replaced with the current one, under their warranty. Do you have any further thoughts or suggestions?

If the Run Times are changing automatically it means you have a Solar Sync sensor with your X-Core controller. Please use this link to learn more about this sensor and how to use it. www.hunterindustries.com/support/solar-sync-introduction

Thanks for watching!

Good question about the delay feature. Use the link below to learn how to get into the advanced feature Delay setting. You would reduce the delay to 0 if you want it off with the minus button when you are in that setting. www.hunterindustries.com/support/pro-c-removing-delay-between-stations
