Congrats on your first night with the new stove, you can successfully run that in this weather without making the house overly hot as long as you tweak the min setting and set the thermostat at say 72 instead of 80. Realistically you can have a fire only the width of a pencil on low, this can be achieved by going to the setup menu in the min position and just slowly tweak it down until you get the desired minimum fire. You have to make sure you let it burn at each setting so that you get a true picture of where it will be. It takes an hour or so to do this unless you get lucky and guess at the right number right away. Likewise you could get a little more heat on high, a half inch or so of ash at the edge of the grate is an OK max setting.
You will also find that with big set backs (difference between day and night you might get some significant overshoot, which is not good for this weather but matters less when it is cold outside day and night. I would set the Tstat for 72 and leave it there for the time being.
