Hi
i ask your help to install my Tunze pump
for the presentation i've install four streams pump 6105 (old model) in my 150x80x65 setup with the front and left side visible.
So for the pump*:
Pump1*: bottom right side, facing towards the front window and a little upwards; I'd like it works with the Pump 2: located at the top, bottom left, and directed towards the rear and slightly lower
i'd like this to works and change every 3 hours with
the pump 3: above the pump 1 but directed upwards and the rear and runs with the pump 4
Pump 4: back, bottom left: and pointing up and front

1 – First question on the wiring. I got pump 1 & 2 with the Y splitter on the L1L2 and other Y splitter with the pump 3&4 on the L3L4 port.
i assume it's ok?

2- question on the tunze cable 1&2: do i need to put tunze 1&2 cable on one Y splitter
OR 2 x tunze 1 cable
OR 2 tunze 2 cable on the Y splitter ?
to be sure?

3- I've now put the 4 pumps in the same group but now only pump 1&3 are working and never change for the two others. How can you change the timer of permanent opposite program?

4- i've got a clic on my tunze when the begin to run. I've read a lot on the forum with the same problem. I've put the right 1-10v voltage at 3 to 8v, nothing change. The problem come from the pump. As i saw on the reefcentral forum , the tunze usa guy tell that we need to change some staff

did someone already try to change this? Did it correct the clic? Can you stop conpletely the pump when it running the minimu (0% instead of 1%)
