Davey Spa-Quip SP500 MkII Circuit Board
Davey, Spa-Quip SP500 (Spa Power 500) PCB.
The PCB is a direct replacement for the SP500A15MK2 and SP500A20MK2.
Does NOT suit first release 500A circuit board replacement - the conversion kit is required if you have this original pcb.
There is a difference in wiring looms and incoming power connection between the 2 versions.
Also the 500A has a manual reset hi-limit that this new mk2 version pcb does not.
* No Returns Accepted unless it was installed by a qualified electrician
