I think this may be my first post, although a long time lurker and follower of the TFP approach/methodologies. I've had a regular chlorine pool for almost 10 years previously. Just moved into a new house with a relatively new (2.5yrs old) salt water pool. It is fully automated with an EasyTouch Control Center so I've been learning a lot since we've moved in (a month ago).
The reason I'm posting today is to confirm my suspicion that my Intellichlor IC40 needs replaced. It's gone into "Cold Water Cutoff" mode. Intellichlor manual states it should go into this mode at 52 degrees +/- 3. The pool is at 65-66 degrees as indicated by the EasyTouch and ScreenLogic App as well as a highly accurate digital thermometer I stuck in the pool to double check. All indicate the pool is 65-66 degrees.
From day one (when we bought the house a month ago), it (Intellichlor/ScreenLogic) has never indicated salt level (on my ScreenLogic, it's always displayed ZERO). But no lights on the chlorinator were indicating low salt or any other issues (at first). My chlorine level was floating around 10ppm and I had my chlorinator set to 0% but it was holding at 9-10ppm consistently (and not decreasing over time as I would anticipate). So all along I've been think the chlorinator was producing [a little] chlorine even though I had it set to 0%. But being new to the SWG pools and the Pentair equipment, I thought I'd wait and see what it did. Well, about a week ago I noticed that the red light (on the IC40) was on (wasn't before) for the Cold Water Cutoff. I went in to the diagnostic mode of the unit and it reads 40% (4000 hrs) on the life/usage and when I'd hit the up button again to see what temp it was reading, no lights would come on for temp. After a few days (of the Red Light for the Cold Water Cutoff), my chlorine levels began dropping (so it was definitely not producing chlorine any more). So after some research, I was sure it was a the flow/temp sensor. I purchased 2 of them figuring they are known to go out and I would have a spare. I replaced the sensor and initially, on startup, I saw a salt reading on my ScreenLogic phone App of 4600 (my actual salt level is about 3500-3600). But whatever, I had a reading and never had before so I thought we were heading in the right direction. Well, shortly after (minute or 2) it went into Cold Water Cutoff again. I went into diagnostic mode, it still read 40% (4000) hours of use and now is reading the 40% light for temp (so 40 degrees +/-5... still way off. So then I thought I'd disconnect [only} the wires for the temp sensor portion of the flow sensor to see if it would try and default to 77 degrees as I thought I read somewhere it would do... and thereby start running again. No luck, still got the red light. I went into diagnostic mode again and ironically it was still reporting 40 degrees (temp sensor not even hooked up, just flow sensor wiring (red and black) was connected) - odd. So I thought I'd try the other new sensor out and wire it in... same exact results. So then I thought I'd put the original sensor back in. It's now reading the 40% light for temp (so 40 degrees like the others). So 3 sensors (2 brand new) are reading 40 degrees so the SWCG being in cutoff mode seems legit (from that aspect)... but the problem is it's no where near that temp... the water is 65-66 degrees. So I'm pretty convinced the SWG is needing replaced as the temp issue is internal to the unit and nothing to do with the flow/temp sensor.
Any other thoughts/suggestions?
If it's helpful - I am fully balanced on the pool, salt is 3500-3600. Pool is ~9500 gallons running an Intelliflo VSF pump, Intellichlor IC40, Max-e-therm 400 for the jacuzzi, and an EasyTouch Control Center.
