I believe the Recteq algorithm for the temperature control is based off an average temperature reading over small intervals of time. If this is correct in theory no test with a secondary temp probe would produce the same results.
I'm always amazed when people compare temperature differences in their smoker expecting each probe to read exactly the same. These tests are always done by placing the secondary probe near the middle of the smoker near the grates. This method is always going to produce different temperature...
Congratulations! You're going to love the RT590. I do find myself using the 590 more but my stick burner and gas grill still have their place. Let us know how the ribs turned out!
Tonight's dinner - Bbq Spatchcock Chicken, Smoked Baked Potato's, and Corn. Used Meat Church Holy Cow Bbq rub and finished it off with a Peach Pecan Bbq Sauce.
Now that the Smoke Fire Gen2 is out looks like they fixed all the original problems. With that said I still like the design of my RT590. I'm not a fan of the flavorizer bars in a pellet smoker. It may work great but clean up is a pain vs the foil lined drip pan in the Recteq models. Also like...
