This ones driving me nuts! For the last week I've woke to find that the zone cycling has messed up, and multiple zones are operating simultaneuously. After work, I've freed them up by cycling thru in manual mode. Yet, the problem persists.
I've checked the controller information for start times, zone times, etc. Doesn't appear that the controller (Rain Bird ESP-
is fried. I replaced it last year, bought it through this site, and it has been operating well until now.
I've watched the pump start relay, a Hunter/Square D, (pulling from a nearby lake) and it behaves well; no chattering or arcing cycling on or off. Also, no signs that the contacts have been arcing.
Any failure modes for the controller that aren't evident by reviewing LED? Is there a mode for the pump start that would prevent full voltage turn on for the pump? I'm stumped, HELP?!!!
THanks
