I am new here so apologies if I am not in the right place. I bought this house with the existing system, I have searched all over but can't seem to find any info on my current situation. I have Pentair Intellitouch I5 v.1060 from 2005. As near as I can tell my system only controls single and 2 speed pumps. I know the system can be flashed, I am not exactly sure if there is a hack to do this myself. I see the interface online but it seems expensive. I also see that I can add screenlogic, is it possible to update firmware through screenlogic if I add it? Or will screenlogic bypass all the need for existing software altogether? I guess, to summarize my question, what is the best way to proceed with adding the variable speed to my existing intellitouch version? I have multiple functions and actuators I would like to be able to setup with different speeds from the pump. Sorry if this has been covered somewhere already but I can't find it. Thanks in advance!
