Excessive smoke in stove, filled the house - HELP!!

Clearly not right. A bag in 8.5 hrs on a low setting is the opposite of what you'd expect. That's what you'd get on almost the highest heat setting. You should be able to go ~24hrs on the lowest setting. Check that you are using the correct settings, because the stove is auguring pellets way too fast.

This.

On HR4 I go thru about 2 bags in around 16-18 hours or 1 bag every 8-9 hours.

If that thing has been factory reset already, then you may need to manually set the feed rates and such.

I did on my stove because I like to tinker and have it tuned in nicely for my home. When it's 0°F outside with a 40MPH wind, HR4 keeps my house at 80°F while using the above mentioned amount of pellets.

Yours is feeding wayyyy too much for HR1. HR1 should get damn near 24-26 hours on 1 40lb bag.
