I have a Carrier Edge non-programmable thermostat for dual-fuel.
Stat works fine........but will make a call for heat immediately after satisfying. No down time.
I cannot find where this stat has the ability to adjust to correct this problem.
T-stat is in good location on interior wall and wired properly (I think). Has worked properly in past. equipment is 3rd-season in house.
My furnace has not shut-off but for a minute or less, unless I lower temp on stat and wait for temp. to drop for a call for heat.
I am an experienced HVAC guy who has never experienced this issue, good thing its at my own house.
PS: I just bought this house.
