I'm going to buy either the Repti Temp rheostat, which I understand to be essentially a dimmer, or the 500R thermostat, which for the price is probably not a high-end unit. My only question is whether or not I can control two different heating units to run at 2 different temps?

I need the heat lamp I have to keep my warm side between 80 - 85. And I need the uth to keep the other side 90-95. Which one is going to do a better job of keeping both units at the right temp?
