Not exactly. They have a controller, with random and wave modes, but it has no speed control, meaning you can't set the max value like you can with the dial on a Vortech. For example, if you run it on 'else' mode, which is a random flow mode, you can't dial back the maximum output.
The ReefAngel, or other capable controller, gives you this plus any other capability you want to program, like syncing them or custom wave patterns. There are other ways to 'dial back' the WPs while retaining their stock controller, but none that I would recommend.
