According to the recently published news story, “Smart thermostats remember for you,” a thermostat that is “just about as smart but doesn’t connect to the Internet” was installed in the back side of this home. (We live in northwestern Denton.)
Only one wire was available to power the thermostat. According to HVAC technician Bill Clark, the thermostat pictured in this story needs two wires to operate, a hot wire and a common wire, as do all other smart thermostats you can buy.
Research shows that the common wire is not available in some applications with a non-heat pump system. This requires battery power to a digital thermostat. Only a conventional thermostat or a programmable thermostat (one that is “just about as smart but doesn’t connect to the Internet”) could be used in these applications … until now.
With a Venstar Add-a-Wire accessory box and diode, you can simply “turn one wire into two.” For more information about this accessory, follow this link:
Note from Peggy: Sam was terribly disappointed after we were able to install an internet-ready thermostat in my house, but not his apartment. (For want of that wire. I wasn’t going to pay to lay more wire in the attic.) He went in search of a solution to that problem and found the add-a-wire device. After I asked him to make sure it was UL-listed, he ordered it, and then installed both the add-a-wire and the internet-ready thermostat in his apartment (which is in the back of the house) himself. He took the photos of his handiwork so you can see what he did.
