If you notice on top there is a red knob. Pull that up and you can rotate the dial without changing the temp, that will allow you to recalibrate it. I believe they talk about it in the directions.
I have a 100W in a 20 gallon and it has been rock steady at 78. When I first turned it on, it was holding at 82 even though it said 78 on the dial. Popped up the red knob, changed it to 82, pushed it back down, then turned the dial down to 78, hasn't budged since.
The only problem I've had with it really is the Aquatop sticker started to peel off, so I just reached in and plucked it off.
Mine is fully under water by the way ;) Every heater that is sold in Canada has a fill line on it, it's just part of their laws, but you really can fully submerge it.
