I'm using an UTH and the Zilla Thermostat.

Thanks so much!!
Sounds like you might have a rheostat/dimmer not a thermostat, a dimmer just regulates the current being sent to the UTH, a thermostat should do as described and monitor the temp to what you put the setpoint at and turn the UTH off and on as necessary. A dimmer style stays exactly where you set it and you will see fluctuations due to room temp changes.
