what is wrong with my ATO?

[jwalker314]

here is my basic programming...

Fallback OFF
Set OFF
If Switch1 CLOSED Then ON
Defer 005:00 Then ON

problem is, sometimes it will run for about a min after the tank is already topped off.. Plus my power went out for a min and when it came back on, the ATO pump went on full blast and flooded my tank (fortunatly the ato tank is only 1-2gallons.)

any reason that could be caused?

i plan on writing a better ATO script tonight

Think you need an OFF command in that statement. This works fine for me.

Fallback OFF
Defer 002:00 Then ON
If Switch1 CLOSED Then ON
If Switch1 OPEN Then OFF

I don't see any issue with the programming. What are you using for topoff? What outlet is this plugged into? If using a low wattage pump (5W or less) on outlets 1-3 or 5-7, they will often fail to shut off. Outlets 4 & 8 are mechanical relays and don't have this issue. Is the float switch functioning smoothly, and not getting stuck?

The Set OFF serves to do that for him.

Im running a MJ400 for the ATO pump, I suppose i can try a different outlet to rule that out, but the pump should be using plenty of juice to trip the outlet off.

maybe it possibly has somethign to do with the variable outputs that i use for dimming my leds (via buckpuck) Its seems as though they have be acting up too (leds flickering when the temp is screwed up. also i notcied the temp dropped to 19.3 excatly at 2am which is when the red LED is set to turn off. I can post the datalogs if that will help at all. in the mean time im going to unplug the variable speed ports and see what that does for tonight (since i wont be home till 12am.)

A MJ400 is rated right at 5W, so if you are not using outlet 4 or 8, switch it to one of these. Alternatively, there have been reports that using a small plug-in GFCI device draws enough additional current to get the Triacs (outlets 1-3,5-9) to work properly.
