So I hooked up a 24v stepdown to 12v coming out of a 1 link port. For. 12v computer fan. All I hear is clicking sounds for the 1link module.
Anyone know why?

Most likely, your DIY rig is overloading the ACC output - drawing too much current.

When I plug it into a eb8 it works fine
An EB8 does not have 24VDC outputs. Do you mean EB832?

Yes eb832
What exactly are you using as a stepdown? It needs to be a buck converter or similar DC-DC converter. If it's a transformer it will short out the port and might explain the problem.
You might be an engineer if...You have no life and can prove it mathematically.

That’s what I used. Followed a YouTube video of a guy doing this. Only difference he plugged it into the eb832 and I went to a 1link
Hi zombie. Which one do you recommend? There are so many I don’t know which one to get off amazon

And I’m only using 1 fan per step down and only using 2 fans total.
But maybe more in the future
That should definately work then. Those fans only pull 0.5W per fan, so you could get away with quite a few on each converter.

Just got off the phone with neptune.
Sounded like they were less than happy to help me lol. Cause it’s a diy project.
They say I’m either over loading it or got a short.
I soldered all connections and each wire has its own shrink wrap with shrink wrap over that for a clean look. So impossible for a short. And red wire went to red and black to black
perhaps a bad DC-DC converter?
Make sure the speed return pin is not connected to anything, you have correct polarity, and the speed pin is taped.
The red wire should go to converter output positive, black to converter output negative, and yellow disconnected and taped (assuming standard 3 pin color code)

so i fixed the issue and it was the converter. the output has to be 12v 5A max... the one i had was a higher amperage
so now onto coding.
i need:
1in_litfan to turn on when my display lights turn on "also stays on when lights turn off when water temp too high
turn on when water temp to high
think i got the codes to work. correct me if im wrong
1lin_litfan
If Time 07:00 to 11:00 Then ON
If Time 11:00 to 07:00 Then OFF
If Tmp > 79.5 Then ON
If Tmp < 77.5 Then OFF
didnt work
i want it to come on when my lights come on then also be over ridden by temp and come on
fixed it. i changed
If Time 11:00 to 07:00 Then OFF
to
if time 07:00 to 23:00 then ON
this correct?
i think im learning this coding stuff haha
If you want it on from 7am to 11pm or when temp is high, you want this.
Fallback OFF
Set OFF
If Time 07:00 to 23:00 Then ON
If Temp > 79.4 Then ON
Min Time 030:00 Then ON

done thx.
can you quickly explain what fallback is and set is please
Please use available documentation for learning basic things like this. The Comprehensive Reference Manual covers both of these. There are also sticky posts here which cover both in detail.
"Set" is covered in a post in this thread: https://forum.neptunesystems.com/sho...ad-This-Thread!
"Fallback" is covered in this sticky: https://forum.neptunesystems.com/sho...About-FALLBACK
