I was just on their website and it seems to be working fine. Here is their contact info page:

They are part of Hayward so they are a major company! I would try calling their support number and asking about the AquaTrol. You don't want to contact one of their distributors, you want to talk to them directly for your questions.

I just tried calling tech support and they are there!
