ecobee Smart Thermostat Premium with SmartSensor
24 VAC forced-air, heat pump, boiler or PTAC systems, checked first with ecobee's compatibility tool
ecobee's top thermostat ships with a room SmartSensor, the Power Extender Kit and a trim plate. The maker's spec sheet covers conventional 2H/2C, heat pumps to 4H/2C, boilers and PTACs on 24 VAC, and rules out line-voltage, millivolt and 0-10VDC systems. Dual-band Wi-Fi, Alexa built in, Siri with an Apple home hub. Read the warranty's installer clause before you fit it yourself.
