How do u use this thing? sooo confusing.. got the red arrow that points to the temperature, and also the red thing u can move from left to right..

I can only tell you this. I am still confused by the setting and I have 4 of them! One thing for sure, once set, they are FANTASTIC heaters. Tops in my book!

I just set mine where i thought the right temp is and wait a day. Then you are supposed to fine tune it with the outer ring +/-8 degrees I think. I got lucky with mine at 84 on the second try so I left it alone.

Man, do I thank God that I have about a dozen of the old style ones.

what's the point of having two arrows?

old style is much better IMO I have it set at 81 and it keeps my water at 81 that's it no need to mess with calibration I guess it's just a nice feture to have for some...

This is hilarious. I have 3 or 4 and am in the exact same boat as you Redear. No idea what I'm doing with them, but they hold temp perfectly!

I think, and I may be wrong, that the dual ring allows the heater to "know" the actual real world temperature of the tank, thereby allowing for exact temperature settings.

I have one that is right on. I have another one that is 5 degrees below the maximum correction that the red ring will let me do. I have to just turn it up 5 degrees higher
