Hello all. I have a Pool Pilot Digital Nano setup on it's 4th season. I've been careful with water chemistry the since new, but this year has been a chore with all the rain we've gotten. I have the water balanced well now with the exception of the chlorine level. Free chlorine remains low and combined/total is even lower - near 'locked' is what my pools store says.
The Nano cell has been cleaned and there does not appear to be any issues with the flow switch. No warnings are on the Nano. When cleaning the cell with a mixture of acid and water, I notice the fins are not caked with anything, but are a dark gray in color.
With the water at 84 degrees and the Nano set for 50%, I read 1v and 5 amps on the self test.
Unplugging the power to the Nano, waiting 30 seconds, plugging back in and immediately going to Boost I get 17v and 5 amps on the self test.
Why am I at 1v at 50%? Is this normal?
Thanks for any insight.
EDIT: the pump is running 24/7 at this point.
