I had my pool installed last July (2012). It is all Pentair equipment and my IntelliChlor IC-40 SWG has never worked. Never worked meaning it always shows a low salt reading (when the salt level in the pool is fine) and will not produce chlorine.
Pentair has replaced the cell 3 times, and just recently replaced the power center and I am still having the same low salt issue. Pentair says they are now stumped and have never seen this issue before, lucky me.
After the recent power center replacement, my ScreenLogic still reports the salt level at 350 and I know the salt level in my pool is in the area of 3,800 (had it tested by 2 different sources). The interesting thing (at least to me), is that when we replace the cell, the power center or any other part of the SWG system, I get a salt reading in the area of 350 (it has been as high as 700, but usually fluctuates between 350-500).
I see a lot of talk on the Internet about SWG's needing to be calibrated, but then I also see talk about SWG's no longer having to be calibrated. I haven't mentioned this to my Pentair rep because I think he would have suggested that first if calibration was part of the install process.
What do you all suggest? I am at my wits end and convinced that this isn't a hardware problem, but an install or wiring issue causing the wrong salt readings.
If needed to help troubleshoot, here are the components of my pool:
- IntelliTouch Personality Kit i5S+3
- ScreenLogic PC interface iTC15 kit
- IntelliChlor IC40 SWG
- IntelliFlo VS 3050 pump
- Pentair FNS P60 filter
- AquaComfort electric heat pump
Thanks in advance for your help as I'm beyond frustrated.
