It does have a temperature control knob that can be turned from markings that say 140 degrees all the way to 410 degrees. I do not know how accurate the temperatures are since I haven't actually tried to measure it, but you can turn the heat up or down. Hope this helps.
The description says the temp starts at 240F (120C) but the dial starts at 140. What the heck? And there are no indicators of what the temps are until you get to the hottest. I will be writing a review after some use, just received it in the mail.
