:help: Furnace Fan Define "On" vs "Circulating" ?? We have a Lennox Propane Fired Furnace with a WiFi Thermostat Control.. The Furnace Fan has 3 Settings (On,Auto,Circulating).. I had set the Fan in the "On" position to keep the Fan running Constent.. Was told we should have the Fan set on "Circulating". Thoughts Appreciated.. Cheers Thanks
