Is my pool/ AutoPilot setting OK?

Using the Bleach Calculator program which offers a CYA calculation. For a 22000 gal pool it would take 3 pounds 8 ounces to raise the from 40 to 60.

It's a handy little program, it can be downloaded here at the forum.

As always, thanks!

I can't comment about your question on cell life, but one advantage of running at a lower power level and a higher percentage is that you have a finer resolution for adjusting output level. When you run high power and low %, each % change is a big change. Also, with the lower power level and higher %, you are adding chlorine more continuously, resulting in a slightly more stable chlorine level.

Let me say that I really appreciate all the help on this forum.
Tomorrow I will be adding the additional CYA to the pool and then lowering the power level to 1(and increasing the output), and testing from there to get my FC around 3 instead of 5.

Are these amps at 120 volts? They draw that high an electrical load?

TW

The volts are DC and usually in the 24 - 26 range.

The 120 volts are applied to a transformer that then supplies the DC volts and amps to the control unit that supplies the DC volts and amps to the cell.

The average load applied to the transformer on the DIG-220 controller, is about 200 watts.

Hope this helps.
