which pumps to use

[Claus K]

Hi
I'm considring to buy two new circulating pumps for my tank.
can tunze turbelle stream 6105 be controlled directly from my 3ex or do i need the controller from tunze as well.
or is there a better choice compared to the connection to profilux.
best regards

directly via the profilux is possible.

but you need a tunze profilux cable ( there are 2 versions ) it has to do with the fact your want to use the First of second control line of the L-port connection.

once you have the cable its just a matter of setting the min / max voltage and configure the pumps.

hi
thx for the answer. but i'm still confused.
1.i can only get one port free L1/L2 so i should buy the tunze1 cable and a y splitter ? i want to connect two 6105 pumps ( one in each corner) and control them seperately. is that still possible, i can see the cable says L1/L3 but on the rear side of profilux it says L1/L2.
or
2 do i have to by an extension card plm-4l and a tunze1 and tunze2 cable.

at the moment i use L1/L2 for an evg box L3/L4 for an evg box L5/L6 for an active splitter (simul-L). as i see it i can only free 1 socket L1L2 by using a y splitter, am i correct or are there some tricks that can be used.

Yes, plus a cable tunze2 cale. Then you can wire
connect port L1L2 to splitter
from splitter to pump 1 with cable tunze1 -> L1 controls pump 1
from splitter to pump 2 with cable tunze2 -> L2 controls pump 2


2 do i have to by an extension card plm-4l

Not neccessary at the moment, do as described above
