I bought a used Pentair MiniMax 100 spa heater, unfortunately, the original wiring was ripped out. I have replaced the transformer, I need to know where the line and load wires connect to, TP, TP/TH or TH. I connect the hot wire to the terminal with the orange wire and can get the burners on but I am not activating the thermostat.
