- pre October 2015 spa control systems fitted with original oval brass bulkhead style elements in the heater.
- Post October 2015 spa control systems with titanium heater element.
- (Titanium heaters have 2 small element penetrations with lock-nuts
- Original heaters have a large brass element bulkhead)
This PCB is supplied complete with wiring harness for all Spa Power 601 spa packs fitted with original heaters or new heaters, due to a software & hardware modification that prevents just the PCB only being replaced.
