So I am the proud new owner of a sauna. It's not a new one, and its one of those infrared jobbies. Something like this should be simple, but it came with zero paperwork and the internet is a dead end - the one I bought is NOS, but likely from as early as the 90s as it predates a website address and the phone number is a dead end.

I managed to disassemble, move and reassemble it successfully, and it starts up and gets warm, but I have a feeling it's not running at full clip. Anybody here used to dabble in these things?

My initial operating questions are the three modes - celerant presumably meaning "quickly" in this case? I'll eventually trial and error it, but it sure would be nice to know I'm not doing anything boneheaded.
