Trane SWT0647 Fan Switch 110-10°F

The Trane SWT0647 is the fan switch that is specially developed for Trane HVAC Systems. The fan is controlled to preserve comfort and maximize system economy based on temperature. When the temperature drops below 110°F, the switch kicks the fan on and starts circulating warm air around the room. The switch turns off the fan if the temperature goes over 10°F to avoid overheating. This automatic temperature control will make your HVAC system run more efficiently, as it will stop needless fan action.
