Honeywell Thermostat Fan Control - Does it work?

I have been using my Honeywell Wifi Thermostat with Home Assistant (HA) for a while now. In the milder seasons it is nice to be able to circulate the air in my house since it is too warm outside to run the furnace and too cool for air conditioning. I see there are ways to set the fan mode in the Climate component, but they don’t seem to work. Has anyone gotten this working? If so, please share.
