Ebb and Flow system controller wiring diagram

Looks good.I see you routed wire differently but you can wire that either way and separate outlets

Yeah I just followed your diagram but in uk we don't have a dual outlet that has separate feeds into them so I have to use separate outlets. I didn't add the leds either but I guess that's up to who build it if they want them or not.

What made you go with float sensors? My pump is simply set to run for 15 minutes every 4 hours. When drained, there's about an inch of water remaining. You'll get a little scum come harvest time, but it's never been an issue.

This is not for a standard ebb and flow table, this is a control bucket for an iws system like this http://www.iwssystems.co.uk/

If the pump stayed on for 15 mins there would be an empty res and a lot of nutrients on the floor

By the way, I now have all the parts to build it so will be doing that in the next couple of days

Thanks again, I built it and it works perfectly although I only used 2 top float switches as I only had 4 in total although I can add another at any time as it seems to be a safe guard against flooding if any of the top switches fail and still works fine without it

Thanks man good to hear. And yes the 3rd switch is optional and is a fail safe switch like you mentioned.

Hey guys, just curious what the drain and fill blocks on the top center are? Relays?
If so can you Identify what 1-8 is?
Im from the USA and our couls on relays are:
13/14= coil
9/12 common of form C relay
8/10 normally closed
1/5 normally open
TIA

I just bought the aircubes system, much simpler looking than this diagram lol
