I was actually just researching how the light shows work with Easytouch and found the same thing. It's a mode called Color Swim where the lights will follow each other in changing colors. It looks like a really cool feature, but I can't see eating up 3 circuits to do this. I'm only going with the Easytouch 4 since I don't have any other features, just need to control the variable speed pump, heater, one water valve, SWCG, and the lights. So I don't think I have enough room to put each of the 3 lights on its own circuit. Plus then you need to have 3 separate transformers mounted outside the box. I think I'll be good with just using the standard light shows with all lights changing at the same time and having them all the same color.
I'm also unsure on which of the above features need an actual circuit taken up in the panel. I know the SWCG uses the built in transformer, so that doesn't use one of the 4 circuits? The heater, I think, uses a circuit (but not sure, I think the heat pump will always be on and I just control the set temp through Easytouch), the VS pump will use a circuit, the lights another circuit, and the water valve another circuit. So I think I will use either 3 or 4, depending on if the heat pump needs a circuit or not.
