To fix your issue, putting the probe in a container of liquid, or attaching to one (like your fermentation vessel, or keg) should give enough thermal mass to avoid overshoot, unless your heating or cooling source has a tremendous amount of overshoot/thermal inertia.
If leaving the probe dangling in mid-air is how you roll, playing with the delay and temp tolerance parameters should minimize heat/cold battles. Your temperature variation will increase, though.
That being said, putting the probe in/on a container of liquid is a better solution. For a fermentation chamber, if the probe is placed on an active fermentation vessel, it will maintain ferm temps much closer to the ideal. For a kegerator/keezer, if the probe is place on a keg or in a jar of liquid, it will prevent unnecessary cycling from door openings and exterior temperature swings.
