I just got this today - http://www.reptilebasics.com/Johnson...d-p-16178.html

I just wanted to make sure I am setting it up right. I set the Setpoint to 90. If I read the instructions right, that means that it will turn the UTH on should the temp dip below 90 and cut it off when it hits 90.

Is that correct or do I have it all wrong?

Thanks.
