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.

SmartSensor (sold separately) unlocks the following additional features:
Smart Home & Away
Automatically adjusts the temperature for energy savings when you leave home and restores your comfort settings when you return.
Follow Me

Seamless setup
Compatible with most HVAC systems
ecobee thermostats work with radiant heating systems, multistage, and dual-fuel heat pumps. Use the Thermostat Compatibility Checker or reach out to our support team at 1-877-932-6233.
Industry-leading reliability
ecobee thermostats are powered by a dedicated 24VAC power supply using a Common wire (or C wire) for consistent performance, even in the coldest weather. The included Power Extender Kit allows for installation in most homes without a C wire.
