With the dimmer suppose you reduce the power to the UTH so it heats up 15*F over ambient, then as the ambient in the room varies the temperature of the UTH will vary right along with it.
I might be miss understanding your explanation but if you set up a UTH on a dimmer won't the temp of the UTH stay constant no matter what the ambient temps are. If your UTH gets to 130 degrees unregulated and if you put it on a dimmer and set it to where it gets to 90 degrees won't it stay at that same temp no matter what your ambient temps are?
