My Jandy system started to "freeze" the last 10 days of so. It locks up every few days and the equipment stops working. I must reset the system to get it working again. iAqualink says its online but won't work. Keypads just freeze with the time of incident stuck (like 8:45 PM).

Any ideas what could be wrong? I removed many of the controls from the system hoping that would be a solution, but problem persists.

Sounds like it is a physical problem to me. If it was me I would cut power to the entire unit (including the power from the main panel) and then re-seat every board including the RS485 connections.
