I have had this controller for a couple months. I only recently started to receive this error, which leads me to believe it’s not a compatibility issue. I checked the wiring to the pump relay. All looks good. I browsed the forum and there seems to be people, who had pump fault errors, remedy the issue with a firmware update. A firmware update might help. What else might I check for? If I manually activate the scheduled program it operates the pump relay properly. Even immediately after program was supposed to run.
Thanks for your time, Mat
