Hi Usacolonel,
Thanks for posting. I understand that you want to know if the system will come on if the temperature falls below the Eco settings. In this case, let me explain that yes, If your home’s temperature gets lower than the "heat to" temperature you’ve set, your thermostat will turn on heating until your home warms to the Eco Temperature you set or If your home’s temperature gets higher than the "cool to" temperature you’ve set, your thermostat will turn on cooling until your home cools to the Eco Temperature you set.
You can check the "Learn about Eco Temperatures and How to Change Settings." article for detailed information about the Eco temperatures.
Please let me know if you have more questions.
Regards,
Jenny
