I was just getting started on installing my wyze thermostat. We have propane heat running through a pretty new Honeywell TH6320U208. Only the R and W wires were connected. Wyze app says the thermostat isn’t compatible. Are there any workarounds or am I out of luck?
Suggestion for the app instructions would be to not have the user take apart the current thermostat wiring until compatibility is determined.
Unfortunately without at least 1 more wire, there is no way to power the thermostat. Do you have the ability to have a new 18/8 wire pulled from the unit to the stat?
Definitely appreciate the help. If I can get him to run that at a reasonable rate which letter would I plug that into on the unit. I’m guessing current r goes into rh, current w goes into w1…
Brian, I have a Honeywell thermostat that I’m trying to replace. The terminal is not labeled but there are the wires connected and a bunch not. The red, white and blue wires are connected. Here is a picture I appreciate any help.
I just tried to run this wire myself 18awg wire from amazon to c on heating unit to the thermostat and I’m not getting power. This is what I bought, is it the right cable?

I’ve got reason to believe my wyze thermostat is defective. Using my new wiring I plugged in the old Honeywell thermostat and everything worked. I tried the c-wire adapter provided with the wyze unit as well. Could it be defective?
The wyze is only powered from Rc. It will still give power to your heating system.
Also try to cut those wires a bit shorter, you don’t want the uninsulated part to be able to touch by accident.
especially this,
That R wire is stripped way too far back, it could easily short against the metal case, possibly destroying your furnace control board in the process.
If you can’t make the wire shorter because you dont have enough slack, at least insulate it with electric tape.
