Customer Reviews

Maybe I'm missing something... Review by Badger Avenger
The "fuzzy logic" setting doesn't seem to be working. It keeps the co2 from dropping under 5-10 ppm, no matter what variable I set the fuzzy logic function at. If I were using a burning in combination with this controller, it may be more of an issue. I would like to let the co2 drop periodically, and then rise to the higher set level, but so far, I can't figure out how to do that.
I don't think I'm using the settings wrong, but it is possible.
All in all, it's been a good product for me.
