Got a Bison Pump that just needs a new controller or just want to have a spare controller on hand for your RPS System? 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).
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
