Herpstat power issues

[Eric Alan]

I think what Eric was referring to was if it moves as in your snake buries it with his body under substrate, then it will run forever trying to heat that substrate, or if your snake lays on the probe, it will try to heat forever also. Or of it somehow gets moved across the cage. Mine cant do that though as its through a hole on the left side of the cage(hot side) and its rigged so it can only swing if the snake bumps it while crawling around.

Close...

UTHs are not meant to heat the environment (i.e., raise the ambient temperature). For this reason, a thermostat can only control it properly if the probe is in very close proximity to the heat source itself. Because of the big drop in temperature the further away from a UTH you get, they don't work safely for our pets when used incorrectly. A UTH (and the floor it's in contact with) can easily be too hot for your snake even though just a couple inches away you're reading temperatures that are perfectly fine. If the thermostat probe gets moved, is buried, is dangling in the air, gets wet, etc, you might as well not even have a thermostat. This is why you always see the recommendation to place the thermostat probe, when using a UTH as your heat source, on the outside of the cage sandwiched between the heat source and the bottom of the enclosure. This keeps it away from as many external factors as possible that will cause it to not function safely.

If you are referring to me,

Nope, it was for the OP since his has such odd swings.

I have two Herpstat 4s controlling my 5 AP enclosures and i've never seen such swings.

Yeah im not saying that drastic of swings are usual. Mine does swings that big because a lot of the times I leave the front door open on my red tail boa cage as she regularly likes to sit with just her head hanging out of her cage. She is the total lap snake and actually likes being social. Of course this is when im in the room to watch her.

I have the probe of my herp 4 sitting under my thg and I have no issues. The probe never moves and temps are fine.
