I think(?) you're thinking of "Adaptive Recovery" which has a few manufacturer-specific aliases.

The behavior is broadly as follows: Consider a thermostat heating schedule that is programmed for 64F overnight, increasing to 70F at 7:00am. A regular thermostat would begin heating at 7am, and take e.g. 40 minutes before reaching 70F. So between 7:00 and 7:40 the temperature is "less than 70F."

With adaptive recovery, the thermostat figures out (or is hand-tuned to know) that it will take 40 minutes to raise eight degrees, so begins the schedule at 6:20 so that it hits 70F right at 7am.

If that's not what you were saying then, uh, ignore me.
