Sorry if this has been asked before. After I do an auto tune, the instructions say to go back and write down the the new PID values. I understand how to get to view the values, but instructions don't say what to do next after writing values down. Do I need to keep pressing set to get out of the program? Also, is autotune only needed if you are running time and temp programs. What if I only cook by temp, say for instance I set probe 1 to 225 and probe 2 to 195 and all other values to 0. Is auto tuning needed?
