Controller odd-predictable flashes

[-klb-]

Do you have any symptoms that might indicate a poor neutral bond to your electric service? For example, when you turn on a large 110 V load, (like a vacuum cleaner or microwave) do some lights in the house dim, while others get brighter? Just thinking that a poor neutral bond could cause the zero crossing detection (sensed on the 9-16 input) to get off, and cause symptoms on the 1-8 side.

I will get back to this later.  Thanks for all of your input.  I have some checking to do.
