Thick or “heavy” wires that include wire nuts are a sign that your system is high voltage and incompatible with the Sensi Wi-Fi Thermostat. If you see thick wires and wire nuts, stop. Reconnect your old thermostat and contact an HVAC professional for help. If you need assistance finding a qualified HVAC contractor in your area, click here.
