The ChlorMaker makes chlorine on a 3 hour cycle. Every 3 hours it starts making chlorine, and based on the power level it will turn off at some point in that 3 hours and remain in standby mode, then at the next 3 hours it will start again. At power level 5 it will be on for 45 minutes out of every 3 hours. If you use the spa and let the ChlorMaker know by pressing the boost mode button, it will be put into boost mode and be on for 3 times the normal on time. Boost mode helps to add the chlorine back after the spa is used.
