Ecobee Smart Thermostat Premium

Whether the thermostat needs a common wire (C-wire) from the heating system to power itself.

Without one it needs the power adapter the maker includes or sells, or it runs on batteries or on the heating wires, which some systems do not tolerate.

The kind of heating control the thermostat is made for: low-voltage central systems (24 V: furnaces, boilers and heat pumps) or line-voltage heaters (120 or 240 V electric baseboards and convectors).

A low-voltage thermostat cannot run a line-voltage heater, and the other way around.

Trim plates ensure professional installation appearance and cover any wall imperfections.

Additional temperature sensor included for remote room monitoring.

Remote sensors provide more accurate temperature readings from living areas rather than hallway locations.

Range: The 2.4 GHz band offers a longer range, meaning it can cover larger areas and penetrate solid objects like walls more effectively than 5 GHz.

Speed: Generally, 2.4 GHz provides slower speeds compared to 5 GHz due to a lower maximum data rate.

Interference: More prone to interference since many other devices (like cordless phones, microwaves, and Bluetooth devices) operate on the 2.4 GHz frequency, leading to potential congestion and slower network performance.

Range: Offers a shorter range compared to 2.4 GHz and may have difficulty penetrating walls and other obstacles.

Speed: Typically provides faster speeds and higher data rates due to more available bandwidth.

Interference: Less prone to interference as fewer devices operate on this frequency, leading to a more stable connection.
