Hi all - hoping JasonLion can chime in here:
I have an AutoPilot Total Control System. Right now, it's in total control mode, which presumably means the system automatically generates chlorine and adds acid as necessary. What I cannot figure out is how to calculate the relationship between ORP and Chlorine PPM readings. I've added enough stabilizer to get my CYA to 40, which I know is on the low side for a SWG, but I'd like to make sure my SWG is keeping the FC level at 5.0, the recommended target level. Right now my ORP level is set at 650. What I cannot figure out is how I determine what that equates to in terms of Chlorine PPM. For example, if I want the system to maintain an FC level of 5.0, what do I set the ORP level at to achieve that FC level? I cannot find a menu/submenu that permits me to set a "goal" FC level in terms of PPM. Any help or explanation would be greatly appreciated!
