I have two heat lamps set on top of my cage that are on a different thermostat than the UTH, to keep the ambient temp correct in the cage. My roommate keeps the place at 72 at all times, so I use them to keep them from freezing. It also happens to work out that the lamps don't come on very often, so I hooked my fogger up to the same thermostat and it keeps the humidity at about 65%.
