Are 2 stage furnaces worth it?
The two-stage furnace is more efficient than the one-stage because it doesn't release as much fuel into the heat exchanger when the home is only somewhat cold. If it's 5 to 10 degrees outside, a two-stage furnace will run in the partially-open position and only use 70% of the energy it normally would.

What is a jumper on a furnace?

Can Amana have 2 stage stats?
The H models of Amana cannot have a 2 stage stat, only one on the market like them. They do as they please so could be erratic.

When the control receives a simultaneous call for both w1 and w2 it knows that the t-state is single stage. In such a case it will use logic to upstage based on run time to satisfy.
