When my Aquirite is on, there are 2 green lights that say on all the time: (1) Power and (2) Generating. My concern is that even when chlorine is not being generated, the Generating light remains on. Every thing seems to be functioning fine; mine is set to generate chloring 60% of the time. Has any one else had this issue with the Generating light staying on? Seems like it shoul only stay on when chlorine is being generated.
