    Running Cor at Variable speeds

    Does anyone run your COR at variable speed or consistent speed? By default, it looks like its setup to run at variable speeds, shouldn't it be consistent?

    Also, do anyone know how to set the COR to stop during feeding? Below is what I have but does not seem to be working. It shuts off during a leak test though.

    Fallback OFF
    tdata 00:00:00,0,0,90,0,0,0,0,0,0,0,0,0,0
    tdata 07:05:00,0,0,90,2,0,0,0,0,0,0,0,0,0
    tdata 10:20:00,0,0,90,1,0,0,0,0,0,0,0,0,0
    tdata 16:23:00,0,0,90,2,0,0,0,0,0,0,0,0,0
    tdata 21:36:00,0,0,90,3,20,0,0,0,0,0,0,0,0
    tdata 23:59:00,0,0,90,0,0,0,0,0,0,0,0,0,0

    You should set up IQ and then use fallback 90 and 100% for normal. When you feed set that for 1 and maintenance to off.

    You might be an engineer if...You have no life and can prove it mathematically.

    If used as a return pump, you should not vary the speed during normal operation, except during feeding. Doing so causes multiple issues due to the speed changing and therefore causing the sump water level to fluctuate. The main issues created by that are adverse affects on ATO and internal/in-sump skimmer operation.

    The COR Task in Fusion sets it all up for you; you should run that task.

    Assuming you are using the COR as a return pump, after running the Task, do NOT use the graphical wizard; doing so will mess up the programming generated by the COR Task. Instead, switch to Basic View to see and possibly modify the programming generated by the Task.

    Running Cor at Variable speeds

    I was curious about this too and first thing that came to mind was sump level would be an issue with ATO... I GUESS we always have out Vortechs...

    Thanks guys, I think I need to go with advance since I'm checking for Leak etc. Basic doesnt give me an option to shut down the pump when there's a leak.

    Yes, it does. That’s where you copied the programming in the first post from. You put the If statements in the program editor box as you already did before.

    When you go to the COR Output Configuration and see the graphical scheduler with the IQ-Level widget at the bottom, that’s Wizard View. Click the third button from the top left to switch to Basic View. It should already be in Advanced Control Type.

    Interesting. My Cor 15 defaulted to a variable pump rather than a constant setting. Even after I went through and added it via a task. I ended up manually setting it to 80% for the vary reason someone pointed about above. My sump level was all over the place and I didn't catch it until later in the day when I got home from work and heard it. Steady state though it is pretty solid.

    I am glad there is a variable speed and display. I think it could provide some good value in flow patterns with my Sea Swirls but alas the sump I have isn't the most flexible thing in the world. I guess I should have shopped around a bit more or made one out of a 40 breeder or something.

    Just curious as to why you'd set fallback as 90 rather than 100?

    I change speeds 2x per day with ATO off - 10pm to 10:01pm slow(5%) - then from 10:10pm to 10:15pm fast (100%), this keeps the plumbing clear, kicks up the sump forcing junk off the bottom into the sponges for less manual cleaning and re-seats the carbon and GFO in the reactors, improving flow and forcing some new patterns in the BRS reactors. The Neptune FMM kits confirms the results, 1st few times flow went up by 10%, now over the day it drops by 1-2% and returns to normal after the exercises. Lastly as the basement (reactor COR) pump flow slows, I up the power to get the last bit out of the RX sponges and media.
