stan,
The only thing I was pointing out was, the major cause of the drawn out resolution was the lack of information.
Not having the complete information on your installation (House Codes / Unit Codes).
On the lighter side:As far as being intuitive, I am a Jr.
A long time ago my mother would call out the name Bill looking for my father, and we would both answer her.
So to avoid the conflict and confussion, from then on I was "addressed" as Billy.
Glad your system is up and working as it was designed to.
