Hi Aldi. I think you might have the same unit I do, but mine is pretty old and is only called the Colloid Master AC. On mine, the green light is what goes on when the unit is making CS. When it has reached the ppm-level desired, then the green light goes out. But the yellow *testing* light (underneath the start button) remains lit, which reminds you that the unit is still plugged in. And I believe that light blinks when the unit switches polarity. That yellow light goes out when you unplug the unit before removing the clips from the silver bars. My unit has no red light, but it does have the switch that allows you to choose between standard brewing time and fast. Mine is always set on standard. Does any of this help you? MA

I was beginning to think my mails weren't getting through at all, but nice to see that this one got through. I don't have the 777 model, but the Universal one. There is only a switch to turn the generator on, and the processing button to start the process. Then there is the green light, which goes on as soon as you turn it on. This is the time you can test the water, but you already know that :-) But I don't recall ever seeing the red light go on.
