Another tip, after you get it set to the temperature that you want to run, put a piece of tape across the adjustment knob that is long enough to stick on each side of the heater's body. This reason for doing this is that the adjustment knob is very easy to turn. It can be bumped and the temperature setting will change. Locking it in place with the tape fixes this problem.
This is a design flaw that should be corrected by Hydor. I've read about people cooking their fish because the adjustment knob got turned from a simple bump.
