2 part question for those who have already installed and are running a PID on an electric element. 1) I have the wiring diagram and get where stuff connects, but I need to know what is the end purpose of the temp control unit that comes with the element. (the original on/off, low-medium-high control knob that plugs into the wall and connects to the element itself) Specifically, if the PID turns it on & off with a specific temp setting, where do you set the control knob?. Leave it on low, medium, high...keep changing it for desired temp per cook, ??? etc. 2) I asked this on another thread but I'm looking for other answers, and some others are questioning the same thing: Where did you mount the PID temp probe in relation to the heating element? 1 response made sense, but it was a small smoker. I am in a fridge conversion where the smoke box is 4'x2' and 16" deep. Thanks so much and I hope this helps others out as well. My build is a slow process, but the pieces are starting to come together. Hoping to get a test fire by the end of this month - we shall see!
