Got ours set at 27, one zone on in the up stairs sitting room. The cool air then flows over the indoor balcony into the family, living, kitchen and games. (and these are not small areas).
If you come in from outside, it feels too cold. The way it's looking, I only needed half the zones we have. Mind you, it's good to know there is more if needed.
18,..............LOL, that would be jumper time. Mind you, I don't have the insulation (not big or is that broad lol.)
