Q: We installed this system last year. Our pool was opened 4 days ago and yesterday, the unit stopped working entirely. There is no way to turn it on. I have checked all electrical fuses, changed the fuse in the unit and tested a GFI's . Is there some kind of work around or way to trouble shoot this?? Very disappointing.

Q: I just purchased the aquarite S3 with 340 t cell. I live in long island. I set for super chlorinated and the online main screen it show only 10%. What does that mean? If set to 100 chlorination and cell temperature is below 60 degrees it show on main screen 20%. Why is that? My pool isn't getting any cleaner afterv2 days still very green. Why isn't the chlorination working on my new AquariteS3? Thanks

A:
The output of the cell is being limited because of the water temp. This is normal. If the chlorinator temperature sensor reads a water temperature of between 50 and 60°F then the percentage out output is limited to 10%. If the chlorinator temperature...

Q: I have a 40,000 gallon pool built in 2006 with a T-cell-15. I have replaced the cell once (approximately 8 years ago). Two years ago, the control system began to provide incorrect readings of the salt content in the pool. The salt cell has always been cleaned at the end of the season. Last year, I asked the company that services the pool to try tune up the control panel but the readings continued to be wrong. The company says that I only need to replace the cell but I am afraid that spending the money on the cell without replacing the control panel could be a waste of money because the problem may lie with the panel and not the cell. What would you advise?
