When power is lost to a system with a sump the water level in the sump will almost always rise up a few inches.  When power returns to the system the rise in water level can affect your skimmer and cause it to overflow due to excessive water level right on start up.  The solution to that problem is having your skimmer wait a few minutes before starting up.  The Reef Octopus Delay Timer will automatically keep your skimmer from starting for 5 minutes to allow your systems water level to go back to normal, before starting the skimmer pump. 

With External Skimmers the delay timer is almost a necessity, as it can keep your skimmer pump from running dry if no water is being fed into the skimmer. 

When the Red LED is on, Power is shut off to the skimmer
When the Green LED is on, Power provided to the skimmer
