Woke up this morning and opened the patio bedroom door without hearing chime. Discovered that the my 2Gig panel had loss of supervision on all my sensors. I opened the panel, disconnected the AC, and went into the installer program to troubleshoot. Unable to find any help, I exited and connected the AC. The screen went black for a few seconds and then to my surprise, the system appeared to reset itself and it now works perfectly. Can anyone explain what happened? Thanks.
