Have peace of mind when the power goes out. In the event of a power outage most sumps will fill with water from the display and plumbing producing a higher than normal water level within the sump. This timer is designed to be used with protein skimmers to prevent it from overflowing due to the excessive water level post power outage making a mess within the system. Also great for external skimmer in preventing their pumps from running dry. Once the power is resumed the Auto Time Delay will initiate and keep the skimmer off for 5 minutes.
When the Red LED is on, Power is shut off to the skimmer
When the Green LED is on, Power provided to the skimmer
