If wifi is disrupted will the controller continue to water acording to the most recently programmed schedules?

More generally are there any modes of failure (other than loss of power to the house) where the controller can unexpectedly halt watering?  It would be unacceptable to have one's garden die from lack of water if the system fails when one is away from home for a number of days.

I'm evaluating whether to by a Netro and one of the things I need is to be able to name zones rather than have a zone called say "Zone 6".

I don't see any users manual on your site to answer questions like this.
