Multi-speed fan systems settings on the thermostat interface

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%.

Capable and compatible.

Our thermostats are compatible with most 24v systems, including Conventional, 2- and 4-Pipe FCU, 2-pipe FCU + Auto Changeover, Highrise Heat Pump, Aux. Heat systems, and accessories.1 (Smart Thermostat Enhanced only supports HVAC accessories connected to the thermostat by one wire and does not support pipe sensors for multi-speed fan systems or two stages of auxiliary heat for heat pump systems. ecobee3 lite is incompatible with accessories.)
