I wonder if I could get any help setting up the following:

Outlet1: Return
Outlet2: Skimmer
LevelSensor1: Refugium level

Right now I have Outlet1 set to filter1 and G1 set to Delayed on so that the skimmer is off for 300 seconds after the Return is turned on.

How do I add the logic so that LevelSensor1 turns off Outlet1 when in error?

Thanks in advance
