Powerful features and compatibility with multi-speed mechanical systems make our smart thermostats the best option for multifamily housing units and commercial buildings.
Optimize Mode for a quieter, more energy-efficient home.
Optimize Mode uses the indoor temperature deviation from the setpoint to automatically set fan speed to the lowest possible setting. This results in energy savings* and improved comfort through a more evenly heated or cooled home, better indoor air quality, and reduced fan noise.
* Per Energy Star, a 10% fan speed reduction lowers fan electrical use by approximately 25%. A 20% speed reduction yields electrical savings of roughly 45%.
