All those issues have been fixed some amazing improvement ,also I was playing with the controller @ MACNA & was very impressed ,the boys from vortech say the controller will be out early next year with manual & preset options .difference between this controller & tuze would be that with tunze the controllers function is a box wave so if you put it on 30% (first setting) & 100% (second setting) it will switch between those 2 points ,with vortech you are dimming the pumps up or down between those 2 ponts therefore less shock to the pump.
Also if you have the older version of the pump please contact any of our retailers you purchased it from inorder to get the gasket.we have limited number of replacement gasket be here in 2 weeks.
Although Tunzes could be controlled the same way with Profilux computer.
Hay Albert Pumps ahoy today
