I have a Sundance Certa (purchased in 2014) Spa. We have recently had a main board replacement. The board was not new - and as far as we know came from a donor spa (unknown what year or model) - but it seems to work ok. I went to enter the circulation pump menu yesterday (by holding 'temp up' and 'blower 1' buttons for 3 seconds) and the menu does not seem to activate. I can, however, access the filtration/heater menu ('temp up' and 'temp down' together for 3 seconds).
Not sure why I can't get into one of the menus. I was wondering whether the board that has been swapped in does not support this feature maybe? Or whether it was accessible via a different button combination. Do the main boards have jumpers on them to enable/disable features perhaps?
Any help would be appreciated. Button console image attached.
