View Full Version : How do I: Shut off filter when Redox goes over nominal value

I would like to program Profilux to shut off the filter (skimmer) when redox gets too high. How would I go about this

background. The tanks have ended their initial cycle. Until I stock it fully, the skimmer is just a little too powerful. My nominal Redox approaches 450. I would like to maintain it at 375 in the short term.

I figure shutting down the filter when the Redox gets too high would help. Just need to figure out how.

Thanks

Hi

set socket function to Redox 1 control upwards.

If the nominal value is reached this socket will shut off

Thanks Matthias. That was easy. :p

However, I also want to be able to shut off the skimmer for a feeding pause, if it is running. I was using the socket as Filter and it would shut down for the feeding pause. Is this where I use the programmable logic?

By the way, I love the Profilux. I have all the basic funsctions running. Now I want to start using the more advanced capacities.

yes, use a logic 1:
function: AND
input 1: Filter
input 2: Redox 1 control upwards

Assign function Logic 1 to the socket in question

Again, thanks Matthias. I will give that a try.
