Smart thermostat for 24V systems

The Nest Thermostat E is a Wi-Fi connected thermostat designed for 24V heating and cooling systems. It supports gas, electric, heat pump and other common configurations with up to two stages of heating or cooling. The frosted 1.76 in display blends into the background while showing temperature and status.

Voice control and app access

Works with Amazon Alexa and Google Assistant for voice adjustments from any room. The Nest app provides remote control and Energy History so you can review usage patterns after you leave home. Buyers without a 24V system or who need multi-zone control should look at other solutions.

85% compatibility with 24V systems

The unit works with 85% of 24V systems including forced air, radiant, oil, hot water, solar and geothermal setups. It handles one stage of heating and cooling plus a second stage of either, along with heat pump auxiliary heat. A common wire may be required for some installations.
