I proceeded with removing the G cable as instructed by the app. And the AC would work, but manually controlling the fan would not work – which seems the make sense because it seems to be done by the G cable (?).
It’s my first time messing with a thermostat so I might be missing something. Any help?
I don’t have the Tstat, but I believe this could be something to do with how you setup the Tstat. When going through the setup, it asks something about your fan doesn’t it? Maybe you selected the wrong option for that one?
Could be totally wrong, just guessing based off of other posts I have read. Someone will see this who is more knowledgeable on this device soon.
The issue is that you need to go back through setup and tell the thermostat that your “old thermostat” has the following wires: R, C, Y, G, W. When it asks for what wires your “old thermostat” uses, what it is really asking is what wires exist in the wall, and this is what determines which outputs it turns on when the wyze is installed. By not telling it that the “old thermostat” has a C wire, it assumes that there is no C wire, and that you have used the C wire adapter, so you must have connected a random wire to G, so it throws an error and doesn’t use that output.
