What is a 52011-708-52?

This is a modified 8804 Enhanced Variable Torque main control board. It has a volts per hertz curve that has a more parabolic shape (i.e., emulating a pump curve) versus a truly linear volts per hertz curve. The lower voltage resulted in the motor running cooler, the motor running quieter, and the system being more energy efficient. It is possible to replace this board with the standard EVT board, 52011-038-52.
