My digital display was set at a 575 setpoint for orp. Everything seemed fine with that (fine for this example at least), then my timer shut it off at 2PM. I manually turned it back on maybe 30 minutes later, (pump and swg go on at the same time with the timer) and the orp setpoint was now 775 or something very high like that. That is the only time it ever happened to me. I changed it back down to 575 and it never happened again. this was two days ago.
Power didn't go out. Battery is good I'm assuming because the unit is a couple of months old.
I'm glad I noticed it, because I'm always curiously looking at the display. I'm going to mount that remote cam on the display someday. I'll be darned if I keep going out in total darkness in the middle of the night just to see what she's displaying. I'd rather look at my Tv or computer screen at the numbers. lol
***Edit** One more detail. The orp setpoint now goes up and down at different number steps. For example, if it went up by 5's 550-555-560-565 etc.., now it goes up by 3's or maybe just odd numbers. I didn't notice exactly, but the numbers I end up with now are weird numbers like 572, 577, etc..
