My Wyze thermostat is not cooling the house. These are the wires I have running on our old Honeywell!
Looks like you have to use the C-adapter, unless you have an unused wire that goes from the air handler to the thermostat. Do you have pictures of the Wyze thermostat and its connections to the C-adapter and from the adapter to the air handler?
You are going to blow a fuse if you do that.
You need to use the top wire labels from your old thermostat.
You will need to hook up the C adapter on the furnace side. Is there a yellow thermostat wire somewhere in your furnace, maybe connected to the other side of the float switch that is that black wire that is connected to Y?
