    • W (White) – Heat
    • Y (Yellow) – Cooling
    • G (Green) – Fan
    • C (Common) – Power for the smart thermostatMake sure you identify these correctly.
  4. Connect Wires to the New Thermostat: Follow the instructions provided with your new smart thermostat to connect the wires to the corresponding terminals. If your new thermostat requires a C wire and you don’t have one, consider using a C-wire adapter or consult a professional.
  5. Attach the New Thermostat: Mount the new thermostat on the wall, ensuring it’s level and securely fastened.
  6. Restore Power: Turn the power back on at the circuit breaker.
  7. Follow Setup Instructions: Complete the setup process as per the manufacturer’s instructions, which usually involves connecting the thermostat to your Wi-Fi network and linking it to a mobile app.
