ecobee Power Extender Kit

Check before you buy

• Electrical: for compatible 24VAC systems only. This is a wiring adapter, not an outlet transformer or battery backup.
• Installation: access to the HVAC control board and suitable existing thermostat wires is required. Confirm your wiring with ecobee before ordering.
• Compatibility: compatible ecobee thermostats only; a thermostat is sold separately.
• Avoid buying twice: Enhanced and Premium already include a Power Extender Kit. Essential and Lite do not.
