I was in the clarity the other day, and the outside temperature cooled down into the mid 60s while I had the AC on, so I decided to turn the heat up a bit. I noticed that the "heat" really didn't get warm until adjusted to the maximum setting. Setting the temperature to even 1 degree below maximum seemed as if it was pulling ambient temperature air from outside. I dont believe the AC was on. The "high" setting was very warm, as expected. Anybody else notice similar behavior?
