Don't forget to order a 3rd Jebao so you can replace a dead Jebao around the 1 year mark. But they are cheap, so replacing once a year is no biggie! ;)

Exactly. I have a spare. But good PSA.

Hey guys, I have an old tunze I am not using because the mount broke. When I find it, I'll post it up and see if is something you guys can use.

Found my old thread. It's a 6080

I have one noisy on and one quiet one, so I've set one to 80% and one to 100% with the Profilux.

Does Apex do 0-5v or 0-10v? I tried setting the Profilux output to 0-5v as suggested, and they only ramped up about 1/2 way... but very quiet.

Got home today and both the pumps had stopped again. Grrrrr

Sorry, honestly don't know. 0-10 sounds right, but I often make stuff up in my head :)

Just measured the output from the Jebao controller, it's 5v max.

Now the weird part. With the Profilux set to 0-10v I get 4.89v at the control circuit out to the pump. There must be a resistor in the adapter for the Profilux circuit.

Temped to just hook them up to an old wave maker power bar.

Weird. I have all my original tunzes still working. I've only had one motor block and one driver box die out of the lot and they were a questionable setup when I bought them (modified or something). My wavebox is going on 8 years old.

Course now that I've said that they'll all die slowly over the next few months...

BTW, when you order RW-20s to replace your Tunzes you can order one of these to control them with an Apex.

I just ordered 2 of these from reef supplies for same price.
I'm out of town but when I'm home next week they wil have arrived I'll report back how they work
