Sometimes the furnace does a better job than anticipated, i wouldn't worry about it, especially if the furnace shuts off.
the setpoint is the temperature you want it to be
cycle lenghts are determined by how much recovery you are requesting. for instance, in the morning when you wake up, you want the temperature to be at its setpoint. what the thermostat will do is make the furnace run a limited lengths during the recovery process.

How do i adjust AC temperature variance on a Honeywell TH5220D1003 thermostat


If you are talking about the difference between heating mode and cooling mode and the room setpoint, you can not change it. It comes from the factory with a 3 degree difference. In other words if you raise the heat setpoint until it is within 3 degrees of the cooling setpoint, for every degree you raise the heat setpoint the cooling will raise a degree.
About all you can do is increase the distance between the heat and cooling setpoint. To do this either lower the cooling setpoint to 3 degrees higher than the heat setpoint you want and then increase the cooling setpoint the desired setting. For example heat and cool setpoints are 67 and 70 respectively, and you want 65 and 73. Lower the cooling setpoint to 68 and then raise the cooling setpoint to 73. Now your heating will come on 3 degress lower than 68, the 65 you wanted and cooling will come on at 73. Remember, the thermostat new setpoints will turn on the cooling at 75 and turn back off at 73 and heat will turn on at 63 and turn off at 65.
You can perform the same using the heating setpoint, just have to look at it backwards. If you need to lower the difference I recommend a 8000 series thermostat. They are the most functional thermostat that Honeywell makes, be in mind they are about 3 times more expensive and many of the setting require a well trained tech to interpret and set properly.
Hope this helps.

Try it with out the programming. There is no fix if the dates and times are correct. Before you call someone you are better off buying one online ($150) and changing yourself. Should not even have to do any wiring, just remove screen and put new one on old backplate. Of course you will have to redo all your run times with the new one. Likely pay that much for the service call just to hear you need a new one. Good luck.

Honeywell rth230b won't shut off heat


Sounds like a relay sticking. Possibly in the thermostat or possibly the furnace relay at the furnace. The next time it happens, unplug the thermostat from the wall. If the furnace still runs then it's the furnace relay.

Hope that helps...
