Your snake must have external heat, unplugging a heat source is fine as long as you can hold at least 80º across the cage (don't feed it while the temp is this low) if you cannot hold this temp I would return the UTH again and place a floor tile (ceramic or stone) inside the enclosure over the heat to prevent the snake from close contact for long time to 110º. 110ºF is warm enough to shut down a snakes digestive system but so is 80ºF as well. Cool temps below 75º with no hot spot is the equivalent to aids in humans it will depress the immune system and leave to door open to infection and bacteria. Reptiles are very closely connected to temps incorrect temps almost always result in sick animals. Why so much importance is placed on thermostats.
