Zone comes on with control in hibernation

I have my controller set to Hibernation mode and all zones disabled, yet my sprinkler came on in one of my zones. How is this possible?

@richinwalla - one possible option would be the diaphragm in the valve failing and letting the valve open.

i was able to turn off the zone with the Rachio app. Would a bad diaphragm respond that way? Thanks for your response.

@richinwalla - the app wouldn’t show a zone running due to a failing diaphragm, so I don’t think so.
