Hello. I have a very old aqualink rs4 from around 1998. From what I have gathered it is pretty easy to upgrade to iAquaLink using the iq30rs conversion kit myself, right? I have a remote control panel in my house and controls in the spa. Will these still work if I upgrade the pcb? Also, the way the pool builders wired my pentair intelliflow, I currently cannot control the speed of the pump. It only runs at the rpm I set at the pump. Will I need to do anything in particular to make the iaqualink be able to control the speed of the pump?
