Advanced thermostat capabilities

Smart Recovery

As ecobee3 lite gets to know your home’s heating and cooling patterns, it learns how long it takes to reach your desired temperature. If you routinely wake up at 6 a.m., Smart Recovery will start heating and cooling your home in advance so it’s comfortable when you wake up.

AC Overcool to Dehumidify

This feature will use your air conditioner to lower the indoor humidity to keep you cool and comfortable if you don’t have a dehumidifier.

Supports two-stage heating and cooling

ecobee thermostats are optimized for one or two-stage heating and cooling equipment. Staging control lets you get the level of comfort you like while lowering energy use.

Fan Dissipation

ecobee3 lite automatically runs the fan after a cycle to maximize heating, cooling, and dehumidification.
