VV compared to VW:
VV ( variable Voltage) you set the voltage to work best with the chosen resistance coil you have installed
VW (variable Wattage) you set the wattage to work best with the coil ( I left out the resistance)
Analogy: VV is like driving your car in the hills, you constantly adjust the throttle as you go up and down the hills, VW is like setting the cruise control on. The car adjusts the throttle automatically to keep the same speed.
As your coil ages, the resistance will change a tad, VW mode adjusts the voltage for you to keep things "even". By adjusting the VW (Watts) up or down is equal to adjusting the cruise control to faster or slower...
