Does your system work fine otherwise? There shouldn’t be anything overriding the quick run. Does it show in the app that it is cutting it short? Thinking there is a chance that it could be a valve issue…?
After talking to Tech Support I have a theory that an integration with Control4 is causing the zone to turn off. Tech Support noted in the History tab of my system that an “integration device” is sending an off command after the zone starts. This could be any integration device such as Alexa, Google, etc but I suspect it is a configuration issue with C4. Will check into it ASAP and report back. THANKS
