ecobee thermostats are compatible with most 24-volt residential heating and cooling systems, including gas, oil, electric, and dual-fuel systems. The majority of ecobee thermostat owners can power their thermostat with the common wire (C wire) or the included Power Extender Kit (PEK).

Installing an ecobee thermostat is an easy process that takes about 45 minutes. If you’re lacking a C wire you can install the included Power Extender Kit (PEK) at your furnace control board and wire it in with your existing thermostat wires to create a C.
