The SmarterSpa doesn't operate on a timed cycle like all other salt chlorine generators. SmarterSpa is the only salt chlorine generator in the world with chlorine detection built into the cell. Traditional salt systems turn on at a fixed cycle which is called the power level, They turn off if they need to or not. The SmarterSpa measures the chlorine, and when it needs more it will start a chlorine generation cycle. Even if you set the chlorine production to maximum, it will not turn on unless the spa levels are low and will not over-chlorinate your spa.
