I also have a Therion 75C and tbh I am really disappointed that I am coming here onto Evolves forum to look for answers instead of Lost Vapes . I have sent them an email to their support asking about the case thermals and their recommended settings so maybe they will get back to me . In the meantime I will be keeping a close watch on this forum to see, and pretend I understand, what transpires . For some, particularly me, the Therion is the pinnacle of vaping mods and it's only thanks to the miracle that is Fathers Day that I could afford it so it's disappointing not to have it working right out of the box . Same thing happened with my C1D2 but atleast VapeDroid had the settings posted to their Facebook page . TBH I'm only posting this extra bit for others like me that might not understand all the technical stuff and want something to read .
