I looked at that link. The purpose of that upgrade relay board appears to be to improve the reliability of the one originally installed in your hot tub. Have you had any problem with yours? If not, I don't think this will help you much.
You need to go back to the Hot Springs people again. Tell them you need the "Service manual". Usually it costs a few dollars (maybe $20 or more). A service manual with electrical schematic is what you need. They should have no problem selling it to you. If they say they don't sell it to owners it means they are trying to protect their dealers at your expense. You will then need to contact a dealer for it. If they say they don't make one, its a red flag that they are half assed and you are on your own. In that case you will need some electrical knowledge or help and figure out your controller by visual examination with an ohm meter. This is how I figured mine out, but I'm an electrical engineer so it was not hard for me.
If you get your schematic (in soft copy form) and can't figure it out I may be able to help you.
