Working with most modern HVAC systems, the ecobee3 lite works to limit the amount of energy used when heating and cooling the home through its eco+ system.

It also includes an AC Overcool feature that can use your air conditioner to help lower the humidity in your home if you don’t have a dehumidifier.
Mobile app – ecobee’s smart phone app lets users program settings, create schedules, and even adjust current temperatures in real time. Remote functionality means that users do not need to be within range of voice control nor do they have to use the control panel to implement heating and cooling changes.
