Replacement Balboa circuit board for the discontinued Viking Spas VKV502R1 board. For install simply move all white wires only to match the original board and in most cases leave all dip switches down. The new replacement board now comes with the plug and click system mounted to the heater terminals. That would be removed before installing.
This circuit board replaces: VKV502R1, 54357, 54380, 53787, 53788
Circuit Boards are a final sale.
