Ecobee EBPEK01 Smart SI Power Extender Kit

Use the power extender kit to simplify your ecobee installation. A common wire (c) is required for 5-wire thermostats. If there are only 4 wires to your existing THERMOSTAT, you can use the ecobee power extender kit to power your THERMOSTAT instead of running another wire as the common (c) wire.

Features

• Installs in place of a running ‘C’ common wire
• Simplifies 4-wire installs
• Compatible with smart si and ems si only
