This week I had to add salt to the pool because my salt level had fallen to 2,800 ppm. I increased the salt level to 3,400 ppm. I noticed that the reported voltage had changed. At a salt level of 2,800 the control unit reported 24 volts. At a salt level of 3,400 the control unit reported 22 volts. The amperage was the same at 6.5 amps. [Level 2]
An increase in salt would increase the conductivity of the water. Does the control unit reduce the voltage in order to maintain a constant 6.5 amps? Is there an advantage of operating the SWG at the lower voltage level?
