Hi, all. I first tried reading through all of the thermostat compatibility threads to see if I can find a solution to my problem, but it seems each are unique. Sorry for posting yet another thread on this topic, but I’m not sure how else to get help.
Just got my long-awaited Wyze Thermostat yesterday, Excitedly began to install when the app on my iPhone immediately deflated my excitement when it told me my system is not compatible. I only have 3 wires behind my current thermostat: Y, W, RH. My carrier furnace and AC is about 10 years old. The wire from the thermostat leads to the basement and is spliced with a 5-wire line that goes to the furnace. So it seems that my furnace can take the 5-wires, but my thermostat is using only 3 of the wires. I am attaching photos of the wires behind the thermostat, the spliced connection between the thermostat and furnace: 3-wires from the thermostat and 5-wires to the furnace, and the description panel showing the model #, etc, of the furnace. I am willing to run new wires if necessary, but just want to make sure that my equipment, as is, will have full compatibility with Wyze Thermostat if I spend the money and time to do so. Pleas help! I really don’t want to return this thermostat! Thanks!
