Lagoon Random Mode
When a pump is in Lagoon Random Mode, the dial is used to set the maximum operational speed, and the driver will automatically randomize the pumps output to simulate a low energy lagoon reef environment. If this pump is a master, the associated slave pumps will replicate the master in sync or anti-sync modes.

Lagoon Random Mode mimics the low-energy reef zone such as that found in a lagoon. A lagoon is protected from the high energy of large waves and therefore the corals that come from this zone are used to slower, more gentle currents than those found in a Reefcrest environment. Lagoon Mode simulates this environment by automatically changing the speed of your pump slowly.

Nei due file PDF ci sono anche i file con le curve simulate del flusso nelle due modalità random ReefCrest e Lagoon.
