I was curious if anyone has figured out how to kill one of the 4 zones while controlling the other 3...I assume it may not be possible.

Interesting. There is only 1 Off button. Have you tried turning off the system and then only turning on Zone 2, 3, 4 from their respective controllers? I doubt that works, but worth trying. I'll try it too later.

I think you’d have to manually close the vents to come close to killing one zone.

Exactly what I was thinking.
OP, why would you want to do this... to keep your takeout from getting cold on the drive home?
