Aqua curbe controllers have suddenly stopped working

Thursday, October 28th 2021, 10:41am

Hi there!

I've been happily using my aquasuite and OCTO for a couple of years now. Two weeks ago though I've been having an issue:

- I've setup my fans using "Curve controller" with Water temperature as the controller source.
- This worked fine up to now...
- However now when the OCTO is set on "curve controller" the fans go to 100%, as if they're not getting any signal
- The water temperature is working correctly
- When I set the fans to power preset they work correctly
- If I go from "curve controller" to "power preset" many times, sometimes the "curve controller" will work correctly

You can see a video of this in action here:

Thanks!

In the video it looks like you are at 0% PWM at the given water temperature, which means that the fans, according to the PWM specification, go to 100% speed.

If you set the minimum power to 5% instead of 0% the problem should be solved.

I think you're right!

Thanks so much! Never would have thought about this!

For now its working - if it causes trouble again I'll report back, but I think we're good!
