Actually ceramic can sometimes be used in TC, but it depends on the coil. I would go to the manufacturer's specs page and read whether it is or isn't a TC wire. You don't want to use a non-TC wire in TC, and vice versa. I don't know a ton about these coils, so I'd recommend looking in the manufacturer's specs and etc.
Hope you get your vape sorted out and glad it's working better for you in wattage mode
