After I suspected the AC somehow affecting this, I did some experimenting with this at my house. I did not have the more extreme heat situation causing it to go way beyond the "safe zone", but did notice consistent changes when turning the AC on to off and vice versa even at the cool outside temperatures we were experiencing. These are running on electric, but I saw very similar results running on gas. I kept the refer control dial at the same position(4).

The technician claimed their service area is at about 70° and did not see the results I saw.
