Ditto. Spent many hours troubleshooting these controllers, most of the time end up replacing the face plate or the whole controller. One thing I have found is the program A start time reset to 12 & 3 happens most consistently with a power outage, be it a full power out or opening the face plate, when there is no functioning battery in place. Now don't ask me why this happens given the program is supposed to be in static memory, but these programming problems seem to occur mostly with program A (resetting or just not working). Also had my share of problematic weather stations. I have one right now the weather station (wired commercial grade) is no longer being seen by the controller. Haven't tried to troubleshoot it yet.
