I'm looking to get another hot tub and having issues with maximum water temp. Seems there is a law in Calif. that prohibits the sale of spas that heat above 104 degrees . I currently have a 1994 Cal -Spa that I can maintain heat in the 108-110 range. I don't want to buy an older refurb and can't get any cooperation on how to manipulate this limit switch .Any suggestions would be great . Thanks . P.S. In Japan , hot tubs are routinely kept at 115 degrees for therapeautic purposes.
