I purchased the WYZE thermostat to replace a non-programmable Lennox thermostat model 51M33. However, the WYZE app is telling me the wiring isn’t compatible with the WYZE thermostat. I have attached a picture of the wiring with the current Lennox thermostat. Does anyone know if this is a show-stopper and I need to return the WYZE thermostat? That would be a bummer. Thanks in advance.
