Installation should be performed by a licensed HVAC technician familiar with low-voltage thermostat wiring. Power down the HVAC system at the air handler disconnect and furnace breaker before removing the existing thermostat. Verify that the existing wiring supports all required control terminals for the staging configuration before completing the installation. Wi-Fi commissioning should follow the manufacturer app setup procedure after wiring is confirmed.
