I built my PID a couple years ago, before Frozone did the group buy, or I would have bought one from him and maybe wouldn't have this situation. Anyway, it sits in my cold basement, around 56 degrees, and the PID says it's 32 degrees. When immersed in ice water (mostly ice) it reads 12 degrees instead of near 32 degrees. Can I assume that it's off by 20 to 24 degrees? When I run my Lyman 20 pound pot, I adjust the set temp by 20 to 25 degrees. Can these things be adjusted to show correct ambient temperature? The controller is a SYL 2352 I bought from Auberins. I'm VERY electronically challenged and re-read the instructions twice and didn't see anything about this. I know it dosen't sound like a big deal, it still works fine while casting, but it kind of bugs me. Any suggestions?
