This feature allows you to control aquarium and terrarium environments with daylight, nightlight, heat source, moonlight, and wave-maker applications. The Power Center can control two sets of water pumps (total of 4 outlets) at alternating intervals of 15 minutes (minimum) or more to create a wave-maker application.
