If the lowest setting dispenses too much food, try putting some tape over the opening to decrease the amount.
Personally, I don't trust autofeeders enough to leave one for two weeks without thoroughly testing it.
To be honest, I'd be just as concerned with the detectable ammonia and zero nitrates... sounds like a tank that hasn't developed it's colony of ammonia- and nitrite-oxidizing bacteria (the so-called biofilter). In other words, the tank my not have cycled, which would be a problem if your autofeeder went overboard and dumped in a bunch of food.
Changing water before you leave would be smart, as would making sure the feeder only drops a smidgen of food. Too bad the fish are so small, or you could leave without feeding.
Good luck, and congrats on the wedding!
