Since I got a fancy SMRT Thermostat, I noticed it has a Cool mode as well as a Heat mode.
Currently it's in "heat" mode but the target temp is like 16 so the furnace never comes on. I don't have central AC; but, if I switched to COOL, would the furnace & fan behave the same as it currently does on "heat", or, would the fan come on more frequently to try to circulate some of the cold basement air and equalize the house more effectively?
Easy question for those who know, hopefully!
