My Smart Si does not power up after installation. What could be the reason?

Please follow the steps below to troubleshoot the issue:

  1. Check that all wires are properly inserted into the terminal blocks at the thermostat. Tug on the wires to ensure they are not loose
  2. Ensure that the power is turned on from the circuit breaker
  3. Some HVAC equipment has a safety switch that cuts off power to the equipment if the equipment cover panel is not closed properly. Please ensure the cover panel of the equipment is closed properly
  4. If your device still does not power on, please call ecobee support at 1.877.932.6233 (North America), 1.647.428.2220 (International)
