Emerson Common Wire Kit
The Sensi Touch model requires a constant 24VAC power supply to operate its Wi-Fi module and backlit display. This kit functions as a diode-leeching multiplexer, allowing the thermostat to share a signal wire to provide a constant return path (Common) to the furnace transformer. It effectively closes the 24V loop without requiring the installation of new structural wiring.
