PoolNewbie2006

Here is a problem for you experts out there.
I have one of the older version Pentair Intellichlor IC40 (v1) units installed back in 2006. This year, I've encountered a problem. My pool is at 82 degrees and the cell light shows red for low temp. The only way I can get the SWG to produce cholorine is to turn on the pump with the heater on. Only then does it seem warm enough to start generating chlorine even though according to the manual, it should start generating above 62 degrees or so. Once it starts generating chlorine, I can shut the heater off and all is well until the next day when the pump starts up again.
Couple of other notes. I called Pentair and they told me to try calibrating the unit (the older units could be calibrated) but no luck. They then said to try replacing the Temp/Flow Switch which cost me $100. No luck there either. The pool store won't let me return the unit so I am out $100. :mad: Interestingly enough, the new sensor had 4 wires (red/black and green/white pairs) while my Intellichlor only has red/black (flow only?). Another thing is that I have an EasyTouch system and the water temperature reading on it showed 65 degrees when the pool was around 80. I tried calibrating but the unit won't let me calibrate above 74 degrees for some reason. Seems like the sensor has gone bad and I am planning to replace it. Do these water temperature sensors go bad over time? Seems odd to me that both the Intellichlor and EasyTouch temperature sensor read low temps.
Sorry for the long post. Hope someone can help and thanks in advance!!!
