So in the app it says that if there are 2 wires going to a terminal on the control board, to only label the one going to the thermostat….It does not specify what to do with that wire after that though….Do I just twist it together with the wire from the C adapter (i.e. in a likewise fashion to the way it is currently connected, just with the corresponding wire from the C adapter instead???
For you, the red Y wire and the white C wire should stay on the furnace board. The other wires should be moved to the C adapter.
