Is there a setting on your thermostat that makes the unit stay on for 10, 15, 20, 25 minutes after you reach set temp. You can change this setting by looking at your manual for the thermostat. Not sure if there is one for this thermostat but mine has one. Mine was running 15 min after set temp and making it cool down 2 degrees lower than set temp. Hope this helps.

Yes you can change that by change the number of cycles per hour that your t-stat looks from for youe furnace. Lower the cycles per hour number and it will increase the range.
You can see how to do it here
I hope that this will help you to solve your problem!
Thanks for using Fixya!!

Most all the Honeywell t-stats can be calibrated...

I am only guessing here but I believe that the thermostat may need to be gone over as far as the wiring from the thermostat to your heater. A thermostat is basically a switch that operates by way of a thermometer. On the wiring it has red and white wires these control the heat section of your furnace/ heater. They also go down the wall to the heater where it should have terminals to a transformer to convert control voltage to 24 volts, red takes 24 volts to the thermostat and white returns back down to a 24 volt relay to turn on the heater. if at any point the red and whit touch any where the thermostat does nothing at all. That means there may be a short some where in the red and white wires. To check this use a volt ohm meter, disconnect the red and white wire from the thermostat and test with one lead on each wire, a dead short reads 0. There may be slight readings thru the relay, so to check only the wires power down the heater disconnect the red and white wires at the heater and again read only the red and white wires with out being attached to anything it should read open. If not replace thermostat wiring. Inspect the wires for cuts where they come thru the wall and go thru the furnace. Most common places where the wire gets cut or pinched is where it is feeding thru the heater case.If all rings out fine it could be a faulty thermostat. This is a lot of instruction but you are looking for a short and this is the easiest way to go about it.

I checked the model #'s and they should interchange just fine. Double check your wiring. On the thermostat Red to Rc (which should also be jumped to Rh), White to W, Green to G, and Yellow to Y. Move T-stat controls from current position to oposite end and back to what you want to run ie. A/C if thats what you want. Move fan control to on and back to auto. (I find this eliminates some close but not quite right settings). This should work. If not look in furnace to verify how it is wired. Any colors that do not match the above will be your corrective action to do at the thermostat. if necessary change t-stat wires at t-stat to match what is in the furnace.
