But, the probe that is reading the temperature is secured to the heat tape so really its not totally reading the temp in the room. Its reading the temp on the tape. So I guess as the room cools down so does the tape which the thermometer reads then sends to the helix to heat up? Is this right?
So really does a drop in room temp. of a few degrees actually cool the heat tape down that much.

I guess the way I'm looking at it is.....if you connect a thermometer probe to a stove top thats 200 degrees and the room temp is 100 degrees....its prob going to read 200 degrees on the thermometer.....now if you crank the AC down and the room temp. is 80 degrees....the probe should still read very very close to 200 degrees since the probe is connected to the 200 degree stove.

Does this make sense to anyone else? I hope I'm not sounding like to big of an idiot.
