Programmability of tunze controllers

[ChadTheSpike]

Hi,

I am close to a decision stage on the age (years ) old question between tunze and vortech. I have some tunze products and your customer service has been outstanding!! I know I would be happy with Tunze products, but Im always keeping my eyes open.

My question pertains to the programmability of the pump control modules. What I would like to do is create a circular effect in my seagrass tank. Basically I want flow to mainly go clockwise for 12 hours then switch counterclockwise for 12 hours. I know I can do this with two pumps set such that they are directionally opposed to each other set on a simple timer such that one is off while the other is on. But I was wondering if it is possible to create a program such that one pump is running with a max output of say 100% while the other runs with a max output of say 20%, then switch?

Is this possible with the hardware/software provided on the 7095 or 7096 controllers?

Thank you very much for any input you have and all of your previous help, I greatly appreciate it.

I searched online to see if I could find the instruction manuals for these controllers that may anser my questions, but could not find the 7096 instruction manuals. If reading the manual will answer my question, please forward me a copy
Using the 7095, can the pump in the "tidal mode" be controlled using "chance flow"?
Thank you!
Chad

Yes you can do what you were asking in your first post but you would want to keep it at 30% vs 20% due to the pump. Anything under 30% can make the impeller "wobble".

Give this a download. It contains the manual as well(start at page 54 of the .888 pdf) as the software for the 7096. You can check it out his way and get a feel for it. You would use the interval setting, the only thing I dont know is if the pulse can be shut off if desired.

As for chance flow it is a combination of Sequential and pulse. Intervals can have the pulse turned off but due to the typical pump placement and not using 3 or four pumps like sequential would the result is just different.

The only thing I dont know is if the pulse can be turned off of the interval patterns in the 7096 software.

Hope that helps

30% would be acceptable... I chose 20 out of my, uh, the air basically I want one pump to overcome the other

Thank you very much for your input

No problem I had a typo above was well

[ChadTheSpike]

ahh, I got ya, so the chance flow isnt a random variation of the pump output so much as a random variation of one of four pumps... Is that right?

 

[shawnz28]

More I read I am not sure I am right on the chance flow. It may be different than I am reading it to be and is something I have never used. In regular sequential the pumps keep building on one another till all are on. I assumed that this was the same other than they were pulsing too. I think we will have to have Roger clear that one up so I dont confuse things

 

[ChadTheSpike]

Roger, could you please verify that the chance setting is a variation in pulse length (at full velocity) of several pumps and best suited for sequential mode (or more than two pumps)?

 

[rvitko]

By chance or random what they mean is that it will essentially be sequential but when pulse is on as well, it will come on at one of the two speeds at "random", it isn't really random but will appear somewhat random depending on how the pulse speed and interval time line up.

Cool, thank you!
