Problems with 4 Channel AC SSR - White String only...all others fine

[jsheehan3]

I set up a model to control and element, say a tree, that has 4 individual AC strings - R,G,W,&B.  R,G, and Blue all work perfectly.  When I program for WHITE, all channels come on.  Any ideas?

you have probably selected RGB as a string type and with that white = all on.  Last year for my 64 string AC mega tree I made 4 trees of a single color and placed them on the layout 1 pixel apart.
