Hmm, so that doesn't do a full rotation like the Eheim? Does the 2nd switch you press also go to ground? If so you could connect the signal wire from controller to both switches that are waiting for the ground path. That's what the controller is doing with a NPN, turning on/off a common ground. If that works you could create 2 schedules back to back for feeding.
