I have all new Pentair equipment which I installed myself along with some helpful advice in the TFP community. I believe that I have done everything correct so far but should my IC40 be connected directly to the Intellichem on external relay or through the COM of the EasyTouch as I have it. The Intellichem is also connected through COM of EasyTouch. My Acid tank is wired directly to the Intellichem. I saw a few different setups online and now I am somewhat confused. All I want is the PH and Chlorine to be managed by the Intellichem as designed.
