Hey Folks. I am looking for some Harmony zone controller experience. To sum up a long story, I need to get the Harmony working with a nice dual stage Lennox condenser but a three speed blower in the air handler, not variable. Will essentially be using an older air handler where cooling currently uses fixed high speed, heating uses med speed and low is unused. I know that the Harmony uses a voltage control to tell the air handler where to set the blower, but there must be a way to operate two or three speed blower based on demand level from the Harmony.

So to reiterate into a question, can the Harmony be configured to operate a two or three speed blower?
