Google is your friend(I find it handy, too!), I went here -
http://www.goldlinecontrols.com/Support/Manuals.aspx
and chose the Installation and Operation Manual for Aqua Rite (standard) and Aqua Rite XL
on page 17 of the pdf file(page 14 in the paper manual)
Diagnostic Displays
Sequential pushes of the small "diagnostic" button next to the LCD display will
cause the Aqua Rite to display the following information:
1. Pool temperature (xx degrees Fahrenheit or Celsius)
2. Cell voltage (typically 22.0 to 25.0 volts when chlorine is being generated, otherwise
30-35V)
3. Cell current (typically 4.50 to 7.80 amps when chlorine is being generated, otherwise
0 amps)
4. Desired Output % ("0P" -- "100P" depending on knob position or input from remote
pool automation controller)
5. Instant salinity ( -xxxx ppm or -x.xx grams/Liter)
6. Product name sent to the pool automation control display ("AL-0" which signifies
"Aqua Rite")
7. Software revision level (r1.xx)
On the 8th push of the button the display will revert back to the default salt display.
Also, if the button is not pushed for 30 seconds, the display will revert back to the
standard salt display.
1. So it looks like your SWCG calls itself AL-0, has software version 1.50.
2. Your salinity is 2.5 grams/Liter (2500 ppm is kinda low, you might need to add salt)
3. Pool temperature is 31(probably celsius?)
4. Cell voltage is 30.9 Volts and current is 0 amps(it was not on when you were reading it,)
5. Your output knob is set at 41%.
You either wrote some of these numbers down out of order, or I found the wrong manual! The more detail (Model numbers, names etc..) about your equipment that you can provide, the better answers you'll get. You can put the info in your signature line. It would be helpful for you to read the Pool School part of the forum to gain a better understanding of the terminology people use here, and how easy it is to enjoy your pool with minimal trouble. Ph is usually what causes eye irritation, with a SWCG, it will rise if you don't add acid as needed. The only way to know when it is needed is to have a good test kit, and employ it daily. Once you feel comfortable enough with the way your pool behaves, you'll love the SWCG!
