This circuit board for spas is reverse compatible with all previous models of the Mini Max PCB.
Product worked as expected and solved my problem of no heat. Easy enough to install.
Functional but not fully compatible with current touch panel button
Second pump does not start only main pump/heater is working
As it turns out it wasn’t the board that was the problem but am going to keep it as the hot tub is 15 years on and being a elec. I know the original won’t last forever.
