Hi evryone.

I have some question about Poweradjust for DDC Ultra.

I have some strange problem. I connect all cables for poweradjust. No jumper are set. I want to control My DDC ULTRA I change power to 80% and my DDC give me only some strange voice).

It it normal that DDC ULTRA has only 3750 rpm. This is value who give me a power adjust. But the blue cable from DDC ( Speed fan show me 4441- 4500 )

Why power adjust show me always 3750.

Please help me.
