Steffes Technical Resource Library

If you own a Steffes Electric Thermal Storage (ETS) heater/furnace, and you're one that likes to tinker or tweak it to your liking, you may have already discovered the Steffes Technical Resource Library (TRL) at https://steffestrl.com. It seems to be hidden behind a login wall that is aimed towards contractors and technicians, but it is currently wide open if you simply visit https://steffestrl.com/files.

Additionally, it's available on IPFS if ever you can no longer access /files on their website:

I may eventually describe my configs I'm using for the Serenity 4210 on this page.
