Tunze controller.

[bruce 1]

Is there an advantage or disadvantage to control Tunze pumps from a RKE or Apex?
Or am I better off using the Tunze controller?

Tunze controller is easier to setup and tune but the Apex can do everything it can and more. If it were me, I would put the money you would spend on the Tunze controller and put it towards an Apex. It allows you to have a separate program for different conditions like day, evening, feeding, right after feeding, power outage, etc.
