I am thinking to replace the Tunze controller by connecting my 6 tunze pumps to prof3ex.
So, I will need 3 GHL ProfiLuxTunze1 wires, 3 GHL ProfiLuxTunze2 wires, 3 splitters and 6 Lines free. Is that correct?

I was also wondering what will happen if I program the pumps under the illumination menu to set them as a light, lets say: 0% at 07:00, 100% at 12:00, 100% at 19:00 & 0% at 22:00 (with min3V and max 8V).
Will that work?
