i guess that makes the best sence, putting the ATO in the return pump's area...but my biggest concern is Overflowing...any idea's to help prevent it?
get an ato with a high limit. makes it so the pump turns off if the float messes up.
here's a wiring diagram i'm going to eventually try to copy.
here's the description from the person that wrote it out:
Yeah, I just used 3 DPDT relays (from Radioshack). These are the ones with a 120V contact rating and a 12VDC coil rating.
The spa timer is found at Lowes and is the 15min variety although you could use the 30min one also. It's just your standard spring loaded rotary style hot tub timer.....lets see.
The float switches are just reed style switches from: (another website so i removed the link)
The 9V power supply is just one i had around the house (AC to DC converter (9V or 12V will work).
I think that's everything? I used a couple of extension cords found ina pack of 4 at radio shack. I also put it all in a project box (also found at radio shack) and connected the floats to the box with some connectors from radioshack.
