Honeywell Home Round Smart Thermostat - Constellation Connect

Honeywell Home Round Smart Thermostat

A thermostat that adapts to your life. You can control the Round Smart Thermostat from anywhere, or let it manage your comfort and savings automatically, so there’s no learning curve, no rigid scheduling — just comfort when you’re home, and energy savings when you’re away.

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.
