I have a couple breakout switches I'm using to mix a new batch of AWC salt water. I would like the PowerHead in this mix tank to run from the time it is triggered full with RODI and stay on until I test the salinity and turn the AWC back on (closed). I'd appreciate any ideas, there is probably a more elegant or robust solution. I do expect this to be something I should be nearby for, but kids can distract you sometimes.
Outlet: Salt Mix Tank Fill (just fills from solenoid to make a new batch of salt water)
Fallback OFF
If PB2 CLOSED Then ON (push button breakout to fill salt mix tank)
Defer 000:03 Then ON (I need to hold the button for 3 seconds)
If AWC_On CLOSED Then OFF (toggle switch for AWC enable is set ON, so don't fill)
If Salt_F CLOSED Then OFF (optical sensor for tank is full shut off solenoid, time to add salt)
When On > 180:00 Then OFF (tank should fill in 3 hours)
Outlet: Salt Mix (just operates a powerhead in tank to stir added salt)
Fallback OFF
If AWC_ON Open then ON
If Salt_F OPEN then OFF (tank is not full turn off)
Defer 000:10 then OFF (delay off due to ripples in water...)
