I think it might be defective, after moving the probe to the right side of the mat, the temperature inside the RUB is only 84F. Won't go any higher. The mat feels barely warm at all compared to before.
EDIT :: I should also get a mat stat instead? https://www.reptiles.swelluk.com/hab...FbYW0wod22gDKw This seems to be designed specifically for heat mats. Also I do have my probe from my current thermostat on the heat mat, I wonder what would happen if I put the probe inside the RUB instead?
