Round ones are antiques.... LolThat's funny. I think of round mercury switches as being the plain ones. I have the middle ground one that is programmable but doesn't wifi or do anything fancy like a Nest. I don't have the extra wire and installation doesn't look straightforward on the Nest if you don't have the extra wire. And since my HVAC units have been troublesome, I'm not messing with that.

Ecobee includes a 'module' for systems that don't have a "C" wire. Also, most t-stat cable is multi-wire but only the ones you are using at the thermostat may be pulled out of the hole in the wall. That was the case with mine. At the furnace, I could see that the cable was 5-wire or maybe 7-wire. I was able to pull the bundle through and picked a color for the "C" connection and connected that same color at the furnace.I don't have the extra wire and installation doesn't look straightforward on the Nest if you don't have the extra wire.
For anyone else, check with your electric and/or natural gas company as many have "online stores" for energy-saving products and many will have rebates. I got an "ecobee 3 lite" for $50 after rebates. It normally sells for $169.I wouldn’t have shelled out the money

Funny, I just watched the video on how to install that module. Looks easy.Ecobee includes a 'module' for systems that don't have a "C" wire.
