I have a Carrier WeatherMaker 8000TS furnace and want install Wyze Thermostat. Attached is the wiring terminals of the furnace. There are four wires going to the thermostat location ( only 3 being used with existing thermostat) , which terminals do I need to connect to a Wyze Thermostat. Thanks for your help!
What’s the wiring to the left of your picture look like?
