It is hard to say, if you sent the controller I could try it, if I fail there would be no charge. It is also possible the microswitch is stuck or broken and that could be repaired.
The 7000 is about $350 but besides pumps it does pH and Temp control as well as lighting with additional features due this summer. The $350 base price includes the temp probe, 4 cables for pumps.
Yes, that is the 7096, for use with new pumps with controller the 7095 or 7096 will require the calibration of the 7090 described in the video. Otherwise the pump speeds will not be accurate as older pumps without controller used a 0-8V control signal, with is 0-6.5V and that is part of why the controller is integrated as it is. The 7096 is Mac compatible, but the 7096 is obsolete and no further updates will be offered, the Mac version was developed by a college student and is less sophisticated than the PC version of the 7096 software. You also have to be careful to never update it for PC as the latest PC version is a firmware generation ahead and will not be recognized again by the Mac version after it is updated.
