I have a NU-Wave (NU-2000) A-24 Control and am having problems with the power to the blower motor. The system is set up for 220v when I hooked the power up all I get is a motor hum. I have checked all my incoming power and have both legs to the control panel. But, seem to only have 120v out to the motor plug.I have been looking for a wiring diagram to make sure I have it wired right. The Control panel and motor set up was new never used 4 years ago. And can be set up for 110 or 220. The blower motor is a 220v motor. Are there internal wiring changes I need to do to supply 220 to the blower? Or has the wrong plug been put on the motor?
There are 3 plugs on the right side of the spa control unit:
A black 5 hole single slot female connector (not sure what this is for)
A blue 2 hole single slot (heater ?)
A red 3 hole single slot (blower motor) is plugged into this one.

Any help or link to wiring prints would be greatly appreciated. Thanks
