I believe it's three clicks of the fire button to rotate through the modes: Ni, Ti, SUS. For the Nickel coil, I recommend starting around 380 F and working upwards until you're happy with the vape. SS coils can be vaped in wattage or SUS modes. In SUS mode, follow the same start and increase until happy.
ETA: You cannot adjust the wattage in TC modes, only temperature. Using the SS coil in wattage mode, start around 20 watts and go up until happy.
Of course, all of these coils need to be throughly primed...
