Overview

The Solopen Power Extender Kit is the perfect solution for homeowners looking to install an smart thermostat without a dedicated C-wire (only replacement for ecobee power extender kit C-wire). Compatible exclusively with 24 VAC systems, this adapter works seamlessly with a wide range of lot models for ecobee, including the Premium, Enhanced, Essential, Lite, such as for ecobee3 Lite, Smart Thermostat with voice control, and also for ecobee 4. The kit features color-coded wire leads labeled R, G, Y, and W for easy identification and a hassle-free installation process. Setting it up is straightforward: simply photograph your existing wiring for reference, remove the four wires from their screws and attach the matching labels, insert the power extender kit according to the labels, then connect the extender kit wires to your thermostat and flip it onto the mounting plate. The compact, clean white design fits neatly inside your HVAC system's control board area. Whether you're upgrading to a smart thermostat for the first time or replacing an older unit, the Solopen Power Extender Kit makes the transition smooth and simple.
