All the logic input to the controller have to be connected to P1
mating connector. The provided P1 mating connector is
equipped with pin 3 and pin 8 shorted to enable the pump start.
The connections should be done with AWG 24, (0.24 mm2) or
smaller wire.
The following table describes the signals available on the
connector.
