Start by setting your temperature limit to 450 degrees and your wattage or power to about 25 watts. Try out your vape. Adjust your temp limit first before changing your wattage. In TC, your wattage is less critical. If you seem to be hitting the temp limit too quickly, bump down the wattage a little. You will find a sweet spot somewhere in there between 430 degrees and 500 degrees maybe. The watts somewhere between 18w and 30w. Various things will affect it, the juice, chain vaping. You're just going to have to experiment and report back what is happening.
Also, read the TC thread. Lots of good tips in there. "Let's Talk Temp Control"
