1993 Dutchman thermostat upgrade to digital

I am trying to upgrade my furnace thermostat. To a Honeywell rth221b . The only thing my furnace thermostat does is operate the furnace only. No ac or fan control. I can get it to turn the furnace on but it will not turn it back off once it's reached the desired temp. My furnace is a dura flame. I have a blue wire red wire white wire green wire and yellow. I out the wires into the slots with the letters initials. Everything is working right except it's not turning the durance off any help here ?

    I didn't program any temps just done the manual set. I turn the temp up to get the furnace to come on. Wait a few and turn it back down below the inside temp. It turns it on and the furnace lights. Once I change the temp back down to below the current temp and it sets it turns the furnace off on the thermostat however the furnace is still lit and running and doesn't go off unless you switch the selector switch to the off position
