The Nest Learning Thermostat is the first thermostat to get ENERGY STAR certified. It learns what temperature you like and builds a schedule around yours. Since 2011, the Nest Thermostat has saved billions of kWh of energy in millions of homes worldwide. And independent studies showed that it saved people an average of 10% to 12% on heating bills and 15% on cooling bills.
Nest Thermostat E
The Nest Thermostat E turns itself down when you’re away. You can control it from anywhere. And its frosted display is beautifully designed to blend right in.
Honeywell Home was designed for crazy schedules and spur-of-the-moment activities. You can control the Round Smart Thermostat from anywhere on your smartphone, or let it adapt to your life as you go. The Round Smart Thermostat is ENERGY STAR®certified and can save energy when you’re away, and get the house warm when you’re heading home. No more wasted energy when you’re out for the night, and no more getting in from work to a cold house. It’ll even let you know when the filter needs changing.
Most thermostats only read the temperature in one place (usually the hallway) which can make other rooms uncomfortable. ecobee4 comes with a room sensor to help manage hot or cold spots.
When you place sensors in your favorite rooms, ecobee4 can read the temperature and detect occupancy. That's how it ensures comfort in the rooms that matter.
