Only just saw this, so sorry for the late reply. If your coil is 0.7ohm then it is not a temp control coil. Set the mod into VW mode (should have been the default mode when you got it), set your wattage to 18W, vape away, if the vapor production or taste isn't quite right try adjusting the wattage up 1W at a time, with a few test vapes until you find where it is best. If the vapor starts to taste burnt, back the wattage down 2-3W, if you don't it will burn the coil & your coil will never produce a good vape when burnt(replacing the coil will solve that). You do not need to set the volts, it's an automatic readout, you can mostly just ignore it in fact. When the device shows "low battery" or similar on the screen it is time to recharge it. Use the charger that came in the package with the Zelos, if you don't remember which that was, then the safe option is the 500ma charger.
