I'm so mad. My family unplugged my temp control for my UTH.

I was gone for ONE NIGHT. And there's signs all over the thing saying not to touch it. Do I really have to put signs on the outlet too?!

Thermometer read 158.0 when I took a reading. The burn itself isn't the worst I've ever seen, just some pink belly, but he looks like he's in pain, moving slowly. A little help? What can I do? I don't have betadine tonight, I will tomorrow, but there's no open sores or anything, so will it do any good? I'm waiting for the UTH to come back down before putting paper towels down. (He's on cypress mulch, but he pushed it away, which is how he got the burn in the first place.) Should I unplug it completely until he heals??

I've not had to deal with this at all yet, please help me.
