Cerick305 Posted October 21, 2021 Report Share Posted October 21, 2021 I have a Cameo Sundance hot tub bought new in 2011. I have NOT recently performed any changes on the circuit board. However, the temperature is now displayed in Celsius rather than Fahrenheit. Anyone know how to fix this? Quote Link to comment Share on other sites More sharing options...

ciderjack Posted October 21, 2021 Report Share Posted October 21, 2021 (edited) From the service manual: P19-1 Jumper JP19-1 Installed: Switches temperature display from Fahrenheit (°F) to Centigrade (°C) I would check your jumper settings on the board first.

Cerick305 Posted October 22, 2021 Author Report Share Posted October 22, 2021 Ciderjack, thanks for your response. I did finally check the switch temp display and no jumper on J19-1. So I added a jumper just to see, and still Celsius. Then took back off the jumper, power back on and still Celsius. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted October 24, 2021 Report Share Posted October 24, 2021 Remove board and check the back for debris or discoloration. Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted October 24, 2021 Report Share Posted October 24, 2021 Is there a Persistent Memory reset on that board? Post photos of the entire circuit board and the schematic on the inside cover. Quote Link to comment Share on other sites More sharing options...
ciderjack Posted November 8, 2021 Report Share Posted November 8, 2021 I believe JP9-5 is the memory reset on that. Turn the power off, put a jumper on JP9-5, turn power on and let it boot up, then shut the power off and take the jumper back off. Restart and see if that does it. 1 Quote Link to comment Share on other sites More sharing options...
