Connect power and fan to operate. Turn potentiometer fully counterclockwise to off; fully clockwise for maximum output.\u003c\/p\u003e\u003cp\u003eThe separate small adjustable resistor on the board (starting speed adjustment) regulates the initial rotational speed upon power-up.\u003c\/p\u003e\u003cp\u003eIf the fan speed changes in the opposite direction to the adjustment, it indicates a reverse-sequence fan. Solder-bridge the (PF) setting point to enable forward adjustment. Always disconnect power before soldering to prevent damage! After bridging, the PWM signal will change in the opposite direction to the adjustment, allowing forward regulation of reverse-sequence fans.\u003c\/p\u003e\u003cp\u003eImportant Notice:\u003c\/p\u003e\u003cp\u003eThis is a 4-wire PWM fan controller. It can only control 12V PWM-compatible 4-wire fans, such as many 12V 4-wire case or CPU fans.
