I have two float switches set in my fish tank. My intention is to have a high-level and a low level switch run a water pump that circulates water between the tank and a sump-filter.
I have a couple relays, but I can't figure out how to get the thing to work. If anyone has ever worked on a sewer lift station you'll know what I want.
I want the water lower until the lower-limit float switch is tripped. Then the motor should come on until the high limit switch is tripped. My issue is that between the two switches I have two conditions; when water level is between float switches and is rising the pump is on. Alternatively when water level is between float switched and is falling the pump is off.
I know there's a basic way to wire a trap so that there are two conditions. Any help would be appreciated.
What I have: 4 poll double throw relay, one poll double throw relay (which will be activated by 12VDC and run 110VAC motor circuit.
One float switch is NC/NO reversible (float=on or float=off) the other is NC (float=off)
