Hunter Indiglo Thermostat 43323... Hi, just purchased a house that came with Hunter Indiglo 43323. House currently has only heat (no A/C). I was told since the basement gets quite cool, i should run "fan only'' in the hot summer months to circculate air. Heat setting on auto works just fine. No issues at all with this. I am having trouble activating the FAN ONLY setting. After trying and talking to several people, I CANNOT get the FAN ONLY option to work. Any suggestions?
