I am trying to wire in my c-wire adapter but the control board doesn’t have a yellow connection (see photos). Is there a way to wire this? ![PXL_20220327_201403187](https://us1.discourse-cdn.com/wyze/original/3X/f/6/f6dae584ad47dbc2345cc566f0ea776e1c0c436b.jpeg) ---

Find the area where the thermostat wires are wire-nutted to the system wires and take a picture of that. ---

Where does the blue wire go at the furnace, and is it in your wall behind your current thermostat? ![image](https://us1.discourse-cdn.com/wyze/original/3X/6/1/61c6f264223ee0fecf5128d64b1257e445f51a2a.png) ---

Good. With the power off, take the blue wire and strip a bit more insulation off of it and add it to the thick grey/ thin yellow & green wirenut here ![image](https://us1.discourse-cdn.com/wyze/original/3X/e/6/e6cf9c7b6813394e4801d2a5867a8d3bc97fab8e.png) Then take the other end of the blue wire at your thermostat, and connect it to C on your wyze. Tell the wyze app that your “old thermostat” has a C wire during setup, and you don’t need the C wire adapter after all. ---

Excellent. I’ll give it a shot. Thank you so much!! I’ll be going out of town for a few days but will post the results when I get back. Thanks again! ---

Ok so I finally got around to installing the wyze thermostat. After I hooked up all the wires as you had said I was getting nothing on the screen I took out the red wire which I had put into the spot labeled RH and put it into the spot labeled RC and I turned on the system and now I had the wyze symbol on the screen of the thermostat. During the setup in the Wyze app though it told me that there was an extra wire that I needed to disconnect, which was the green wire. Is the green wire not needed or is something else incorrect? ![Screenshot_20220409-111124](https://us1.discourse-cdn.com/wyze/original/3X/7/7/77c3e0c3e55a1e95b93c8afdab86adb622d65b80.png) ---

Did you tell it that your “old thermostat” has a C wire? If not, it would try to have you install the C adapter, which you do not want to do. You should tell it that your “old thermostat” uses the following wires: Rc, C, Y, G, W. ---

Well, I thought I did, I’ll restart the setup and make sure. Be right back with the results ---

Usually if it says you have an “extra wire” it means you forgot to select that wire as existing on the old thermostat, or it thinks you have a C adapter installed. ---

Well it seems to have made it past the error, now wants to know what fuel W1 uses. I have a gas heater, is that what the W1 is controlling? ---

yes. W is heat, Y is the air conditioner, and G is the fan. [Next page](https://forums.wyze.com/t/wiring-the-wyze-thermostat/223291.md?page=2)
