i don't understand ato/switch codes.

What you have in post #15 looks good to me.

Ok.

I got this from Curt a while back, I had it set up like you have your code, after it failed I emailed Curt to make sure the code was correct. This is what he gave me:

Fallback OFF
If Switch1  CLOSED     Then OFF
If Switch1  OPEN       Then ON 
If Switch2  CLOSED     Then OFF

I have the same floats so if the code does not work take off the c-clip and turn the floats over. This code allows the bottom float to control the level. If for some reason the bottom float gets stuck and the water reaches the top float it will shut the ATO outlet off overriding the bottom float.

you might want to add a max change statement so the switch does not turn off and on all day. I set mine to 30 minutes

I don't see how switch2 could fail. It's brand new and might only be used once or twice.

Wires might get disconnected leaving it in OPEN state.

This is what I put in the ATO pump outlet:

Fallback OFF
If Switch1 OPEN Then OFF
If Switch1 CLOSED Then ON
If Switch2 OPEN Then OFF
Defer 001:00 Then ON
If FeedA 000 Then OFF
If FeedB 000 Then OFF


FeedA for feeding.
FeedB for maintenance.

I just thought of something. The defer command applies to both switches, right? It should probably not apply to switch2 because if switch1 malfunctions and the pump is stock in ON you wouldn't want it running for one minute past when switch2 is tripped because that might overfill the sump.

Defer applies to the entire outlet. So in this case, anything that turns the Outlet ON will be delayed by one minute. Switch2 is turning it OFF, so it won't be affected.

So the defer command only applies to ON. That makes sense.

 

[swearint]

Well, you have the choice of Defer ON and Defer OFF, each behaving as appropriate. You can have one or the other or both in an outlet.
