This circuit board for spas is reverse compatible with all previous models of the Mini Max PCB
Finally it works but two pin and the plastic base of it was hurt in transportation. If it was in a box it was safe. I use the plastic base of my other card and crush out the pins...
Reconnected everything and was extremely pleased to have a working spa again.
Nice to know that when parts break down there is a part source to get you back up and running like new!
