Thats why you leave the "Rockets" to the "Rocket Scientists".
Your register temperature will vary with the outdoor temperature, the
backup heat and the things I mentioned below.
I dont know if it will use more or less electricity. It doesnt matter.
What you should be concerned with is that the unit is working within
the designed parameters of the equipment manufacturer. Thats why you
use THEIR performance charts and instructions. You need to find
someone that knows how to do that and can explain it to you.
