If fan control is enabled, the system sends a command to activate the fan.

4. Monitor Fan Operation

The system monitors the fan’s operation to ensure it is running as expected.

5. Adjust Settings as Needed

Users can manually adjust fan settings through the Home Assistant interface if desired.

Postconditions

The fan operates in conjunction with the thermostat settings, providing enhanced climate control in the home.

Optional Enhancements
