I own a VS-3050 and would like to add automation to my pool. Since I already have the variable speed pump, and want to make use of the variable speeds in my system's programming, does it make sense to stick with automation from Pentair (I'm thinking Easy Touch 4), as they can talk directly to the pump over the serial cable? Otherwise I have to add an Intellicomm for a few hundred dollars, and consume a relay or two of the automation system to control the pump's speed, correct?
