On the better models, a temperature probe in the oven area tells the controller what the temperature is and if it is below the target it tells the controller to feed more pellets and air. The best manufacturers, like MAK and Memphis, have designed their own versatile custom controllers that are easy to use and can hold a temperature within 5°F, tighter than many indoor ovens.
Pellet grills come in many different sizes with a variety of features.
