Definition of "On" & "Circulating"? The Furnace Fan has 3 Settings (On,Auto,Circulating) I set the Fan to "On" to keep the Air moving or so I thought.. Was told Fan should be set to "Circulating"?? Thoughts Appreciated , Cheers Thanks...

I assume those settings are on the side of your thermostat, right? What brand/model do you have? All that I have seen say ON/AUTO and I leave mine on ON all of the time to constantly circulate the house air.

It's a High Efficiency Lennox Model.. The Thermostat is an iPad Size WiFi Control.. When you Tap on Fan Icon a 3 chose Setting pops up. On / Auto / Circulate... The Furnace Fan is a 2 Stage type.. According to the Manual lowest fan setting runs at 40% , then when Burner Kicks In Fan speeds up... My original query is what's the difference between "On" Constent vs "Circulate"??

What brand stat do you have? The stat is not part of the furnace but it controls it.
