Well when I look at that chart it would seem that it is a variable. But...
Now it has been a while sence I have installed one of these. But as I recall
The variable don,t have a black,yellow,red and blue wires to select fan speeds. The variable speed motors are a differant looking beast are they not. I was wanting the "DC" motor for the energy saving and low air flow of the continuous fan. I have a pretty good air filter "system" that I want to take full advantage of.
Anyone... I got to get this little problem of mine figured out. Don't they make a 70,000 BTU 3 ton? Does anyone know what it burns (btu wise) in low fire.
I need to find get the model number for the 80% two stage with the variable speed blower motor. PLEASE!
