Thermostat compatibility

[Ken.S]

Here’s a standard wiring diagram, red is typically the power, white is typically for heat. It’s possible the green is the C wire (common wire). Since you probably won’t have any access to the furnace control panel, you’d probably need to check your wiring with a volt meter. If you measure between red and green and have 24VAC, the Wyze thermostat may work for you.
