simnala,
If the unit is in the "Boost" mode, the output lights will flash left to right.. Push the More and Less buttons at the same time to shut off Boost.
I noticed two thing that concern me..
1. The salt light is not green.. or red.. I'm not sure why that would be???
2. An IC20 for a 16K pool is way undersized. My guess is that you will need to run the unit at close to 100% for 24/7 to produce the amount of chlorine needed.
Is this unit connected to an automation system?
Think maybe you could narrow down your location a little??? Hard to give any advice is we don't have a general idea of what your climate conditions are..
Thanks,
Jim R.
