Got a Bison Pump that just needs a new controller? We have tested a dozen of these out in the field now and they are all working. Very similar circuit board and hookup. Note: Please check your voltage and make sure your system is less than 100V DC (open circuit).
Inputs: P+ P- Solar Inputs (Maximum 100V DC input voltage) B+ B- Battery inputs (optional) U V W (same as 1 2 3) for Pump Wires Tc Th Tank Wires, polarity doesn't matter Wc Wh Low Water Sensor Wires, polarity doesn't matter
