The Turbelle® controller is a pump controller for all Turbelle® pumps with an electric motor, which is used to set the variable pump performance – especially for models without an integrated Turbelle® controller. It can provide a wave motion simulation, oscillation flow, an automatic search for the resonance frequency when the oscillation flow is used, and it is also equipped with a food timer. If the Moonlight 7097.050 (not included in the scope of delivery) is attached to the Turbelle® controller, the night mode operation will be activated automatically. If this controller is connected to a second controller with the 7092.300 cable, a further pump can be connected and controlled, for example, to provide a wave motion simulation or an oscillating current. A third controller can be added using the Y adapter cable 7090.300.
