Another post on Water change
Evening, hope all is well.
Well like the title says im attempting to set up my water change system. However I want to start it manual and not automatic, which is fine. I went ahead and created a timer but dont have any of the days checked. I have looked all over these forums and read the programming guides. I just cant work the bugs out and get what im trying to achieve. I have three sensors hooked up to my Profilux 3 (no splitter). One is an optical sensor and the other two are float sensors. one float sensor is a dedicated ATO so we will leave that alone. My optical sensor is toward the bottom of the sump as a fail safe to shut the pump off if its exposed to air. Now what I would like to do is when I start a WC, my drain pump would kick on, draining the water. when the water level hits the bottom optical sensor then it shuts off my return pump all while still draining until the required time has been met. Once that has been met, then a little delay and then the new salt water gets pumped into the sump until it reaches the top float sensor turning off the new salt water pump. Then have the return pump turn back on after a few seconds later.
I would like to achieve all this and still keep the bottom optical sensor as a fail safe for the return to shut it down just incase. I also have PL used to shut the skimmer off for maint and feedings. I would also like to keep those settings the same but still shut off the skimmer for the water changes.
Any help would be appreciated.
