Also when you move your current thermometer probe set it under your substrate on top of glass where the middle of heat mat is. I have a 4 of those yellow thermometers and mine are all off 2-4 degrees hot or cold so I highly suggest one of the acurites I mentioned.

I don't have a thermostat but it won't get hot enough that needs to be turn off I think. And I am gonna get a Digital Infrared IR Thermometer to measure the temp.
