I'm in the planning stages of my pool. It will have a spa, in-floor cleaning system, a waterfall, and future solar. The waterfall will (switchable via a valve) pour into both the pool and spa.
When using the spa I would like to turn off the part of the waterfall that spills into the spa with an automated valve. This puts my valve count to 5. I have read in the install guide that a valve expansion board is available (P/N 520285) but it looks like that is only for Intellitouch. Can I use that expansion board or will I have to go with Intellitouch?
