I am assuming you have the new Infinity Touch control (black). If the screen is blank, you've either lost low voltage power (an issue at your furnace) or the unit isn't properly seated on the backplate. Pull the thermostat off of the wall and reseat it properly and if this does not work, you'll probably need a pro to come troubleshoot low voltage issues.

The green leaf is "eco mode." It generally will reduce the running pressures of the system, meaning you spend less on energy and have longer runtimes, but it will reduce cooling capacity. On the less brutal days this is a great option. It's better for the system and better for the energy bill. However, there WILL be days where eco mode simply won't keep up.

As you may know, heat pumps will not work in extreme cold outdoor ambience temp. It is why the aux heat is there as a supplement.
7 blinks indicates a furnace roll out switch problem. Lack of airflow, lack of combustion exhaust flow, switch fatigue, clog on air filters. The roll out switch senses fire overheating the heat exchanger box and if the temp exceeds the switch (thermal switch) operating temp, then the switch activates and stops the fire and triggers the alarm.
