Nest Fan Control

[jsharrar]

When you select the fan only mode, the nest thermostat runs the fan for a default amount of time (mine runs for 12 hours and then turns everything off). On the Nest app, you can select to run the fan for a certain amount of time so all other heating/cooling features stay as set but you can run the fan for 15 minutes.

Allow the default time that the fan runs to be easily changed, or when you click the fan only mode it asks for the time you would like the fan to run so everything else doesn't get shut off after that time is over.
