Recteq RT-590 temp spec on the website states 180-700 degrees. The control on the RT-590 goes from Lo, 200 to 500 then Full mode (after 500 not sure this is correct title). There is NOT a 180 degree setting or a 700 degree setting. I spoke with tech support. These are numbers during ideal lab test environment. Again per tech support the Lo setting is possible from 180 with 25 degree swing but not committed to holding 180. Again from tech support Full Mode might reach 700 degree but could swing temp not sure how much. This would have been more ethical to know since I was hoping to create recipes where this is a stable and functional reality. The Yoder is starting look better al the time.
