I just received my Wyze Thermostat. I did the survey before I purchased to make sure it was compatible and it said my system was. However, I am at a standstill.
I only have a 4 wire system, and it tried to walk me through the steps to connect the C-connector to the circuit board.
My system doesn’t have a circuit board, as apparently many do not. My house is a 6 year old Palm Harbor Modular home with an air handler system. The existing 4 wires are hardwired with wire nuts into the system.
I have attached pictures of the wiring diagram, along with pictures of the old thermostat, new thermostat, the old and updated wiring of the C-Adapter.
I am not getting power to the new thermostat, so I assume my C wire is incorrect. I have reconfirmed all connections are solid.
I do not have a meter to determine which wire carries the 24V needed to correct the C-Wire connection.
Edit: Updated photos with labeling and moving G wire to C at theromstat.
