Agreed. I thought that feature was fascinating, it worked extremely well. The Honeywell in my midwest home did a perfect job of learning how long the 17-year-old furnace took to heat up the house in the mornings.

The heat was set to go back to the daytime temperatures at 6 AM, and I began to wake up at about 5:47 every morning when, like clockwork, the furnace kicked on to reach 64 degrees before I rolled out of bed. Well played, Honeywell engineers.
