rheobus power problem

[eddybrown]

I recently added a rheobus to contol my AKASA nebula LED fans better, and after a couple of days i noticed something strange going on. If I turn the knob for the fan on the left it changes the brightness of the LED for the one on the right. And it also changes the brightness of the actually LED in the fan. It doesn't work the other way round. Any ideas how to fix this because its really ennoying, having 1 knob that affects both fans. <BR><BR>I have a sunbeam rheobus with 4 ports. It runs barewire connections rather then 2/3pin plugs.

it should actually do that with all the fans. because a rheobus actually lowers the voltage to slow the fan down or raises the voltage to speed it up. and the leds are wired into the fan so they should dim and brighten with it when you speed it up or slow it down.

Yeah i know by using the rheobus it changes the voltage, so the fans dim and all that. Its just that one knob will affect both fans... maybe i didn't explain very well. If i turn one knob i expect it to change the corresponding fan, not both of them. Its like if you connect two lamp bulbs in parallel the first one is brighter than the second, but if in series then they're the same. This is what its like with my rheobus as the 1st knob affects the voltage of both fans, which shudn't happen. It also affects the brightness of the other LED on the rheobus.
