I currently have my RODI/ ATO system plumbing into my sump. I have a solenoid inline commanded to turn on for 10 mins if my level sensor gets dry. Question is, how would I setup a second level sensor to shutoff that same solenoid if it gets wet or Too high? Don't know why I can't figure this out.
 
Turn the Solenoid OUTPUT into a Generic and make it 2 INPUTS.

input count only has a blue 1. how do I make it 2? I already have 2 level sensors plugged in.

Im Still confused.. I added the second input. But, the active when wet or dry does not make sense.. I need to be able to select "DE-activate" when wet.
Both inputs when changed to wet or dry only say Active. Active means solenoid on. I need solenoid off when wet

If you need it to be "de-active" when wet, that is the same as "Active when DRY". Active means the OUTPUT will turn on. So if you have the OUTPUT Active when DRY, that means when the sensor is dry, the OUTPUT will turn ON.

that logic works well for the bottom level sensor. But then I as the water level rises I would like the TOP sensor to deactivate the powered solenoid when wet . To take priority in other words.
 
You are trying to use "Stateness" which is something that is not supported on the HYDROS yet. Are you trying to create an automatic water change or have the container of water wait until it is empty in order to refill itself and then stop when the top sensor is under water? That requires the control to remember the previous status of a sensor which is something that we will be adding soon but not available yet.

Exactly. A water compartment I would like to refill with a bottom level sensor ( Active when dry) Then de-activate the solenoid when the Top Level is WET. so a constant range of liquid is maintained.
 
Search for my question:

ATO - DI reservoir automation​

Follow Danny’s answer to my question - I use this to keep my DI storage tank between Hi & Low sensors. It has been working well so far. It’s a work around until the Hydros software is updated to have this functionality built in.
 
You could also accomplish this with a second solenoid after the first that stays open unless the full sensor is wet. So your water would have to flow through 2 solenoids before it gets to your reservoir. That's what the programming in the link is doing, but this might be easier for you to understand.
 
I know I'm late to the thread, but just wire the coil of the solenoid through the "Too high" float switch. That way, even if the control system gets stuck "on" or otherwise fails, there's no way for the solenoid to even be on.
You just have to make sure the float switch contacts can handle the current of the solenoid. If not, add a relay kind of like Fuppets mentioned above, and put the float switch in-line with the relay coil.
