It's not really a channel, just a splice direct to the motherboard. It's really meant for a 4pin fan like the stock intel pwm fan. The controller is just splicing this and making three analog channels from that splice.

You could also potentially splice into another rheosmart for more channels, but I'm not sure how many splices you can do. I know the AC F12 fans splice/daisy chain like this for multiple fans, so I would assume you could splice 3 or more controllers, but not sure.
