We built our pool 23 years ago and at that time installed the latest innovations in controllers, a Jandy Aqualink RS6. This controller is still functioning properly. But recently, we have replaced the heater and installed an Astral E 35 SWG and Pentair VS 3 hp pump. We also recently installed the WaterGuru. My question is when do you make the decision to upgrade to the iAqualink at a cost of anywhere from $799.00 to over $2000.00 based on receiving 3 quotes so far. Is it worth the expense (I cannot see any payback) for this type automation?
