Google T3007ES Nest 3rd Gen. Learning Thermostat - Stainless Steel (w/ sensors)

Description

New - open box, Nest Learning Thermostat and 3 Nest Temperature Sensors (new - unopened).
Bought this for my parents, turns out it's not compatible with their system though. I opened the thermostat box but never installed it. The thermostat is brand new and comes with all documentation.
As a bonus I'm combining this with the Nest Temperature Sensors I bought my parents as well. The temperature sensor box is still in it's original plastic wrap and has never been opened.
Don't be like me, check your compatibility before buying.
