I use a UTH, but don't know how to control the temperatures accurately. I understand what a rheostat does, maintains a preset temperature. My question is this, is there a rheostat that will give you the ability to give a low temp and a high temp? For example, leopard geckos need a higher day temp than night, so if a rheostat only maintains a preset temp, how do you lower it at night without turning your heat source off completely?
Thanks, Rigger
