The circulating fan feature allows the fan to circulate air when the system is not running. You can custom select how often the fan should run each hour.
The feature can be set in 5% increments from 10%-100%. The percentage represents many minutes per hour the thermostat will run the fan.
Example: If you set the circulating fan to 50%, the fan will run 30 minutes every hour.
If any calls for heat/cool occur in that one hour period, that run time is subtracted from the overall run time for the fan for that hour.
Example: If you set the circulating fan to 50%, and your furnace runs for a total of 15 minutes during that hour, the fan will only run independently for 15 minutes at the end of the hour.
You can set the Circulating Fan feature from the thermostat or the Sensi app.
