what you more than likely have is a thermometer, which reads the temp. a thermostat regulates the temp of the heat pad to a temp you set it to by turning it off automatically when it gets to hot and on when goes below the temp you set
Oh! That's my bad. Do you have to buy one with a thermostat? Most UTH's I saw online didn't come with one. If not, how would you hook up a thermostat to turn it off? Sorry for all of the questions ><
