Changing Heart Rate Zone on Fitbit Charge HR

Now that I know where to change the heart rate zone, I have a couple of questions. There is only one custom heart rate zone. What does that do compared to the 3 automatic zones? My heart rate does up pretty quickly into the fat burning zone even around the house. What can I set the custom heart rate zone to get the minimum amount of calories burnt?

To the best of my knowledge, the zones are for your reference only. They don't impact the calorie calculations...0

Nope, merely goals for you to like stay between for a workout.
Their selection of ranges and the names slapped on those ranges is just to give a place to divide the workout time between. I've never seen any HR range start at 90 for Fat-burning or recovery as normally called.
