Can you explain why this is required? I have a problem in my Intellicenter with some sort of bug where switching between pool and spa schedules occasionally results in that relay not being activated in pool mode. This results in my chlorine dropping. The only fix seems to be leaving it hardwired to be on and relying on the flow switch to activate or deactivate it. I also have an issue where the INtellicenter "forgets" that the system configuration should be set to using the SWG in both Pool and SPA mode. It will periodically set it only for pool mode, and then when the spa circuit is on, it sets the output to none (even though it is hardwired to be on, chlorine output is set to off). This can only be corrected by changing the system configuration to re-set the SWG for pool AND spa.C,
Did your IntelliCenter come with an internal SWCG power supply or do you have an external power supply?
Is the AC power to the SWCG's transformer wired through the Pump/Filter relay as required??
