The link jets put up is correct. Mine came in today as well and it doesn't come with instructions, just the instructions that jets posted that are online. Now for further instructions if you open the ragnarok software and click any of the question mark "?" buttons it brings up instructions on how to switch modes, turn on/off mods, and what modes do what. If you have any other questions let someone know, including myself because idk how many other people have this model btu I do and can test stuff for you and let you know how it works if you have any issues.
