Honeywell makes a bunch of different thermostats. The older types just used a bimetallic coil with a mercury switch. As the heat went up and coil expanded and unwound a bit and this would cause the mercury in the bulb to flop to the other side and open the contacts and turn the furnace off. I hope this is what you're looking for. New ones use thermistors, which change resistance as heat goes up or down.

Find Honeywell on the Internet and work your way toward owners manuals. Using the model number of yours, you should be be able to find the manual.

If standard mercury, heat anticipator can be adjusted by sliding it to higher # for longer cycle; If digital, and programmable it has to be programmed through settings. If mercury, adjust small arrow up or down as needed from .1 up to .8 by gently sliding by hand. .4 is standard setting from factory.
