Fan only
My furnace has only a two wire thermostat (no A.C.) and would like to run the fan only to circulate air in my house. We have a vent free heater in our living room. It keeps that room quite warm but the rest of the house gets cold. If the fan only would run I could circulate the air threw the entire house.
any help would be great. Thanks

Depends on your furnace. If it's a newer furnace it's prepped for air. First thing TURN OFF FURNACE!Than all you gotta do is run three or four strand to the unit. Hook up wht to W red to R and green to G. Then you'll need a heat/ac stat hook up wires the same way.

Turn furnace on. Switch from "AUTO to ON". And the fan runs.
