Nest thermostat

[dowens21]

Have old Honeywell home thermostat.  Only have 2 wires. 1 red. 1 white.  Have older home.   I’m lost. Do I need a jumper.  Help

I think you need the Google power connector, which is supposed to be free however I haven’t yet figured out how to get the free version; pretty frustrated…

Appreciate your answer. I've ordered one already, coming to the same conclusion myself.

Heres how I found mine for free:

If you follow the Google home App installation process, by going into the app and hitting the big + in the top left. Then scroll down and find thermostats, then just keep hitting next. Eventually it will ask you which wires you have and will give you a diagram of boxes to check. So just make sure C isn't checked (I only had a Red and White wire so I only checked W & R. It will then ask if you connected the Google Power connector or not. Hit no, and then it will take you to the google store page to order one at 0$. Takes a few days to arrive. Only need one, even if you have multiple thermostats. Ive watched some videos about connecting it to the zone controller on youtube; seems fairly straightforward for my setup. Hope that helps you find it.

Thanks! I revisited the home app and followed your process to a successful solution.

Recieved the power connector this week, plan on looking at the furnace this week. The zone controller is mounted on the side of the furnace- hoping I can put the connector in there to work on the two thermostats. Old house. Nothing is ever as easy as it seems around here.

Found a video on youtube for my specific zone controller (Can't remember specific model # off the top of my head but was Taco Brand) and the nest power connector. Super simple installation after I found that. Seems I'll need a second one for the second zone, but the first one is working and I've been playing with it all night. House feels much better now.
