The new controller is 3.5" x 5" x 1"
For an "Advanced" controller, it is lacking in user friendliness. I have one with two 230's. It's difficult to set the max flow for programs. I put mine on the OGC and set the max to be 40% and everything was fine until I went out to run some errands. I came back and all my sand was in the corner of the tank and both pumps were running at 100%. I'm sure I probably did something wrong or missed something, but seems if I set max speed to 40 on the program, it shouldn't allow the pumps to run at 100% at all.
I changed my program over to the random and set the max to 40. Everything seems to be holding well now. I will wait till someone comes out with better instructions than comes with the controller. Yes, I've seen the video by CoralVue and you can follow along in the video and sometimes when the say to press this to get that - It doesn't work.
holding with what I have for now.
