I have Thermostat Scheduler adjusting a Thermostat Controller. It seems once the fan mode is set, it can't be changed under modes without deleting the mode and reconfiguring it.
In the photo clicking on the red circle 'ON' or the AUTO above it does nothing. But clicking on the Blue circled "Fan Mode" pulls up the selection box below this chart to adjust it.
I do only have On/Auto. But it doesn't toggle. They are all set on Auto now. If I click auto, auto stays. Even if I click "update" or done and come back in...stays Auto.
I can delete the mode and recreate with what I want. The first time when it says "Fan Mode" in green it pulls up the selection box.
