I have a 2005 Sundance Cayman 780 series. Just replaced the Circuit board. Everything working great now but the temperature is displaying in Celsius. Can it be changed to Fahrenheit?

      Brian if it is a Genuine Sundance Spas PWA it will have a set of jumper pins just to the left of where you plug in the topside control.
      Jumper 1-2 on enables 15 amp logic, Jumper 1-2 on enables 30 amp logic, Jumper 1-2 off enables 40 amp logic
      Jumper 3-4 on not used, Jumper 3-4 off enables 1 pump operation
      Jumper 7-8 on enables Celsius temperature display
      Jumper 7-8 off enables Fahrenheit display
      This genuine board also has surface mount terminals for the heater where you old PWA likely did not.

    We replaced our mother board and now the hot tub is reading is Celsius. We have a Masterspa Downeaster. Any ideas how to switch back to Fahrenheit?

      Hi Vicky. The temperature toggle is typically controlled by one of the dip switches in the bank set of switches on a Balboa board in a Downeast spa. If the new board you put in is a direct match for the old one you should be able to follow the schematic on the back of your control box cover. It will indicate which switch toggles from farenheit to celsius. If you purchased an offshore board you may have to contact who you purchased it from if the bank of switches don’t match your old board. It’s recommended to reset persistent memory as well after changing a dip switch if it’s a genuine Balboa board.

    I have the same problem with a 2009 hotsprings Prodigy. I replaced the old board with a new board I bought direct from hotsprings, but now the temp. Is in celcius and theres no way to change it back to Fahrenheit from the topside control. Any ideas? Thanks for the help

      Hi Jacob. If your Prodigy has the proprietary Watkins controller you should be able to adjust one of the board jumpers to toggle between Celsius and Fahrenheit. Typically the schematic on the back of the controller cover will tell you which jumper. If they switch to a Balboa system already on yours you will be able to toggle one of the dip switches in the dip switch bank. The back of the controller cover will also tell you which dip switch to move.

    I have an Apollo Spas Cascade model from around 2013 or 2014. We lost power and the display changed from °F to °C. I don’t do the math so good any more so converting on the fly suuuuux. How do I Americanize it again? It has happened before and I forgot the button sequence to push.

      Dave, on the back of your control box cover there is a schematic. It shows where all your dip switch setting are and the function they perform. There is dip switch for Fahrenheit/Celsius there.

    I have a J345 Jacuzzi brand manufactured in 2004. Changed circuit board, now in celcius. My control panel on top only has 5 buttons ( 1- +, 2 –, 3- light, 4- 1st pump, 5- 2nd pump). The J300 series manual doesn’t cover changing to Fahrenheit.

      Hi Nathaniel. The temperature conversion setting is done through the PWA jumpers. If you give me the part number of your PWA I may be able to help. Alternatively the person who replaced your PWA should be able to set the jumper for you.

        If you take off the front cover of your controller there should be a schematic on the back of the cover. It should show a set of 10 dip switches that correlate to your circuit board. One of the dip switches is a toggle between Celsius and Fahrenheit.
