I don’t understand where it get it’s to power keep digital panel to store settings? Sure it don’t go back to default settings?
No. The settings are stored with no power. That is what non-volatile memory means. This is just like a smart phone or other device where the battery is either dead or removed. The settings and apps are still there when you repower the phone. A lot of devices operate that way. For example, you can replace the batteries in a TV remote control, and the settings are maintained.

The function of the 9-volt battery is designed to allow the initial installer to program the controller on a new house before the house power is turned on. That way, the installer doesn't need to return to the house after the power is turned on. The 9-volt battery has enough power to program the controller, but that is all it can do. The battery is not needed to maintain the controller settings during a power outage.
