Profilux II plus aquarium controller

[Matthias Gross]

I'll try to clarify it:
we have the splitters YL2-1 and YL2-2.5, one is 1m long, the other is 2.5m
They have the same function: Just double the ports, no crossover
The splitters are suitable for lighting and pump control
If you want to connect two controllable pumps on one port (eg L1L2) you need: 1 splitter, 1 cable ProfiLux<->Tunze1 (the pump connected over this cable will react on L1) and 1 cable Profilux<->Tunze2 (reacts on L2)

Thanks for the explanation matthias we have the same confusions in the UK.

That explains it perfectly. Thank you. Do you guys sell a Y crossover adapter or is this something that we would have to buy locally at one of our electronic stores? This would be for stuff other than the Tunze's such as two LED lights, or a light and the fans, etc.
