7096 future software recommendation

[Kenfuzed]

I have been using a 7096 to control my 6105, 6055, and also tried with an old 6000. I love this controller and the ability to set up via a software interface.

One thing I'd like to see in future versions is the ability to choose a lower pulse than 30%. Currently you can set the low end to any percentage from 100% down to 30%, but below that it jumps to 0%. I would like to experiment with a very slow speed when pulsing to eliminate the start "clack" when going from 0-100%, say 5% so the pump never actually stops rotation. The clack of my 6055 especially drives me (and my wife) insane so I have to run 30-100.

Great product and I hope that being software based it will have the ability to grow with more features in the future.

The low setting of 30% is actually not just the 7096. The 7095 and 7094 as well has this as a lower limit. I believe it is done to protect the pump motor.

There also if a fix for the clicking of the 6055. There is a new impeller and spacers that will rectify this.

Roger will be on Monday and can tell you more.

ah, good to know. Regarding the 30% limit to protect the motor I had thought that but then why do they allow the pump to cycle on/off, seems like that would harder on it.

Roger has already been incredible in helping me with other things in the past, and service has been so good I can't imagine using anything but Tunze.

I have an old 6000 on my other tank that ended up getting buried in rockwork. I've been too lazy to move things so it has been running from within it's cave for 2 years without service and it still blasts like it were brand new. Their products are seriously BUILT!

I will check in later about the 6055 snap sound.

The 6055 snap is caused by a loose fitting propeller, it should be tight on the shaft and not free spin. Or, a disk is needed under the drive unit to serve as a shim.

Imagine the drive unit is like a gyroscope, when the speed gets too slow it starts to wobble and clatter, that is why speeds below 30% aren't possible.

Ah, here I thought it was supposed to be loose like that. I don't see a shim so maybe that will help as well. Is there a prop & shim kit I can buy?

ok that makes sense now.

They are a very small disk- 6025.740, every pump should have one, but some need 2. PM me your name and address and I will send them, but only add the disk if the drive unit alone doesn't solve the problem.
