Hello all,

I am looking for a solution to a project I am trying to close out. I have built a waste tank that is to be filled till it reaches a certain level, and then drained till it is "Empty". I have a 2 float switches. One is at the bottom and it activates(allows current to pass through it as soon as it reaches 45 deg. The other switch, which is located at the top of the tank, also activates at 45 deg. I would like to purchase a switch/controller that allows the water level to pass the first switch without activating the pump, and then when the top switch has been brought to 45 deg, activate the pump till the lower float switch is no longer at 45 deg. Any products you think might be helpful to build this circuit? Let me know, I'd appreciate the help!
