So i’m getting ready for yet another dry cold northern winter and I figured I should look into beefing up my ST setup. I am interested in buying a smart thermostat that will work with existing wiring in this house. I live in a top floor duplex that only has heat. So I have window A/C units and plug in humidifiers to supplement my lack of a more robust system. I do have heat. Here is the wiring for my existing dumb thermostat.
I work at a big name tech company so I receive discounts on a variety of tech throughout the year. My hope is I can score a discount on an Ecobee3. My concern is I’m not sure I have the wiring to support such a device. Do I? If not what Z-wave enabled thermostat would you recommend?
