Auto Top-Off Schematic?
I'm looking for a schematic for an auto top off system I'm trying to build.I have two float switches and a relay,not sure how to hook it up.
I want to have the lower float set(min.level) to energize a relay coil and a upper float set(max.level) to de-energize the relay coil.
What i don't understand is when the lower float drops, the contacts close and it energizes the coil.As the float starts to rise its going to open the contacts so how is the upper float ever going to come into play?
I'm thinking a second relay but kind of confused about it.
Any suggestions or ideas how to do this?
