I am also using the jump start thermostat. You just plug the UTH right into the tstat. I set it to 90 it kicks in at 88 and turns off at 92 so it's always between 88-92. My guy is in a 27qrt with the tstat probe taped to the under side of the tub between the mat and bottom tub. I have an acurite thermometer that reads for humidity as well with the probe set inside the tub underneath his substrate on the hot side. I check the hotpsot about once a week with my temp gun. Hope that helps!. Cheers
