I have read several threads about the easytouch and can't find anything specific to my needs, so I decided to ask in a thread. I see that the solar option can also be used as "aux extra". I want to use this for another actuator, but I see it only has a two pin connection and my actuators have 3 pins...Is this possible to do? Right now I am using valves A and B already as aux 2 and aux 3. with aux 1 used for my pool lights. I was hoping to use another actuator for my water fall, but can't figure out how. please help. thanks for the info. I can post pics of my setup if that helps. My builder has discharge line split to feed either floor system/returns or I can press aux 2 and actuator closes off that path and sends the water to my features (waterfall, sunshelf jets, deck jets) aux 3 is currently on the floor system/return line so I can toggle between the two. That leaves me with running all features at same time or none at all.
