Prepare Wires
Follow the tips for security:
1. Make sure that the diameter of wire is 18-24AWG;
2. Make sure that the length of exposed wire is 1/8 of the whole wire.
CAUTION: Make sure your system voltage is 24V AC. If the old thermostat is labeled 120V or 240V, or has thick wires with wire nuts, your
system is high voltage. Then do not install the Smart Thermostat, and contact HVAC specialist.
