For a new PropellerBreeze you need the PropellerControl2.1
The 2.5 version was for older versions.

Thankyou for the reply

Sorry to hijack but how do you know the difference between new and old versions? (i bought a 4 fan unit second hand)

Can you send pic of it so we can see it

Here is what my Breeze looks like. Can you tell if its the newer or older version?

I got mine a month ago

Are u using use under the tank or for the top.

OK so mine looks to be the order version. I don't have a sump so its running over tank.

the difference was the plug sitze - 2.1 or 2.5mm diameter

the 2.5 was used until 2009

Thanks Matthias, can you confirm from the above picture that I have the breeze that takes the 2.5mm plug?

this breezer is not 4 years old!

so it has 2.1mm plug

Thanks. That might explain why the 2.5mm controller I have connected to it is not driving it at 100%!

no, this has nothing to do with this problem
