I just got dc controls new eco 2sp controller, My question is it has wires for high speed and low speed I have a lincoln mark 8 fan and only use 1 wire. Right now I have both high and low speed wires from the controller going to that 1 wire on the fan and when it runs the controller seems to hunt between high and low speeds am I wrong in how its hooked up?
