Wonderful, it really comes down to who's working.

Do you know for sure 2 wires are VCC and one ground and not 2 grounds 1 VCC? The DC ports are controlling the GND pin so both channels would dim together if connected to them. RGB strip lights are usually VCC + 3 grounds so each ground can be connected to it's own DC port.

Ah yeah I forgot about that feeder, glad you saw it.

Is the return pump just 24v, 2 wires, or have a signal? You might only be able to turn it on/off plugged into the power bar.

Let me know how things go.

the pump has 3 wires

I have opened the controller and is how you said. 

I will try to add some pictures
