I have an ET8 that I plan on upgrading. Primary reason for upgrading is that I want the Pool Cover functionality of disabling things when the pool is closed (like the slide - yikes!) which will also allow me to deactivate circuits (like remembering to turn off the lights) when the cover is closed. It looks like there's an expansion module that makes the Intellicenter aware of the pool cover state with a sensor which I can easily add.
That being said, I'm wondering how you determined what you needed to order? I have a single body of water, and I already have the relays in my load center, so I basically just need the transformer, circuit boards (enough to get me control of the 8 existing relays and a single valve), control panel, and the AtoD Pool Cover expansion module. I'm guessing that you got your relays with whatever IntelliCenter components that you ordered, so you were OK with purchasing these then. I don't want to re-purchase the relays if I don't have to...
